" Get the hell out of here, she 's gonna
go up!"
And boy, did she go up.
On November 13th , 1969, a single
engine plane came in for a landing at
Princeton Airport. Suddenly it no sed
down and c rashed into the ADR offices.
Miraculously, no one was hurt.
The quote above came from the pil ot of the plane . Hi s
prediction was correct. Gasoline sp lashed over the roof and
walls and within seconds flames were roaring across the
frame building. The photo above gives you some idea of
extent of the fire and destruction. What you can not see ,
however, is the remarkab le story of what was saved , not lost.
ADR came through the crash, fire and flood with 95% of
ou r software libraries intact and operable. Thanks to two of
our own proprietary products , Librarian and Autoflow .
We use Librarian as a source program retrieval and maintenance system . All maj or sou rce programs are stored on
tape in the Librarian master files . Th ese tapes were
removed from the burning building before they could be
harmed. The equivalent of ove r a quarter of a million cards
had been placed on Librarian tapes . It would have taken four
20-drawer file cabinets to hold thi s many cards . These fi les
could never have been saved. Even though innumerab le
card decks and vast quantities of printer output were totally
destroyed , the work they represented, safely stored on
Librarian tapes , was easily resc ued . The information on
these tapes , includ ing commentary on the historical devel opment of the source programs , enabled our programmers

to get back to work
in a fraction of the
time that would have
been necessary
without Li brarian .
Autoflow, our
computerized flowcha rtin g and documentation syste m, was the second hero
of our saga.
Autoflow made it po ss ible to immediately regenerate flowcharts lost in the fire. Without Autoflow, man ual re-creation
wou ld have been needed .
Try to exp lain what thi s costs to the fire insurance people.
We did it the hard way, but we think our unplanned demon strat ion proves quite a bit. Not all accidents, mishaps and
losses will be as dramatic as ours.
But you neve r know what will be lost, torn , mishandled
or mispl aced .
Li brarian and Au toflow saved us inest imable time, money
and effort. We never used the term before, but both products
se rved as vital " insurance" in co ntinu ing our normal operation s. But possibly in your business, this aspect is not
important. After all , things like accidents and fires only
happen to the othe r guy. For a planned , peaceful demon~
stration of Autoflow or Librarian, call or write:

Remember what elephants
never do?
And you've probably
heard that an elephant will
hold a grudge for years. .
Especially against the fool
who would feed him tobacco.
But the truth is that
elephants are quite fond of
chewing tobacco (so long as
it's not burning at the time) .
And only elephant doctors
have very strong feelings
about it at all.
We ask this irrelevant
elephant question to jog your

could cost this user
his share ofa
multi-billion dollar
market.
That's why he depends
on Gerber Scientific
and Hewlett-Packanl.
In the automotive market, being second with a hot new body
des ign just does n 't make it. That's why car manufacturers
are turning to computerized drafting systems, like those
made by The Gerber Scientific Instrument Company,
South Windsor, Connecticut.
The auto industry knows that computers can mean the margin
of difference-when they're working. But when they're not,
yo u just might be " last under the checkered flag ." That's
why trouble· free performance was a key factor in Gerber
Scientific's comp uter selection for its Series 1200 and 700
co ntrols. These drafting systems make it possible to bring
fresh new auto design concepts to market in reco rd time.
Ge rbe·r's systems are also slashing design time and costs
in electronics, aircraft, garments, maps and other detailed
work that used to take weeks of manual effort .
Sure Gerbe r Sc ientific chose our 2114 computer because they
knew it co uld do the job. And was priced right. But more
important, they knew they could count on superb reliability
-and depend on world·wide HP servi ce and support
back.up-if and when needed . We have 14 1 service centers
in the United States and a roun d the world. For an OEM,
this can be a ve ry reass uring fact .
There are other reassuring facts about our small comp ute rs.
Like Direct M emory Access, a feature now ava ilable with th e
new H P 2114B. The DMA option gives you the flexibility
to use high-speed peripherals. And it makes possible the
acqu isitio n of very hi g h-speed data. Yet this computer's base
pr ice is only S8500 . If you're looking for something a bit
more powerful, try the HP 2116B. It's the heart of our
popu lar time·share, real-t ime executi ve and disc operating
systems. Cost: $24,000 .
Get the full story on computers you can depend on. Call
your nearest HP sales office or write to Hewlett- Packard,

The low cost Tally 1020 incremental 1/4 -inch mag tape unit
transfers data incrementally at
120 characters per second and
continuously at 1600 characters per second. Unique among
all incremental units, it can
backspace and rewrite a single
character or block of characters
anywhere in the tape (try that
on your cassette ) . Other features include new DTL logic,
error checking, simplified construction and maintenance,
280,000 or 560 ,000 character
storage on a 3-inch reel, and
low tape wear because of single
capstan drive.

Tally's answer to the reel question.
It's funny how those of us in the peripheral equipment business get carried away by new devices
from time to time. A few years back, a lot of us thought punched cards would be displaced by
paper tape. Then magnetic tape equipment came
along and you know what the doomsayers said.
Fact: More cards and paper tape are in use today
than ever before, even as mag tape use increases.
As a matter of fact, Tally thought so much of magnetic tape we developed a line of mag tape equipment to complement our broad paper tape line.
Now, we come to the latest controversy in data
handling, reel-to-reel versus cassette. Tally's prediction: both will share a part in an ever growing
market. Parenthetically, our view is illustrated by the home entertainment field. Although cassettes are in the limelight, for full fidelity recording and reproduction, nothing beats reel-toreel handling of music tapes. 0 When we add up the key factors, we
find both cassettes and reel-to-reel offer distinct advantages in a data
handling environment. 0 Reel recording offers greater storage capacity, faster continuous transfer rates to and from the CPU,and
faster asynchronous transfer rates to and from the communications
4 •
lines. Reel recording offers high speed incremental recording and a
.... . - -. ..• ... •
history of proven reliability. The cassette offers easy loading and ease of handling, and it
doesn't require a precision drive. Cassettes require less physical room and are more manageable
in a less than ideal environment. 0 So our advice to you when you design a working storage device into your data system is to choose the method best suited to
solve your application problem. 0 For information on the Tally
1020, as well as other Tally products, please write us for our inTALLY ·

Introducing an old company.
We've kept quiet for 17 months. But
now we ' re shouting. Because what we ' re
advertising is real , manufactured, and
delivered. It works, and it's available now.
It's our Datamanager. A business-minded
computer that saves you a fortune in
application. Business-minded because it
processes reams of data in single operations.
See our Datamanager systems in several
applications (including turnkey systems) at
the Spring Joint (Booth #43010).

Take a programmer to lunch.
And leave him there.
After all , programming devours a large
part of your budget. But not anymore.
Atron's Datamanager is a completely
new kind of mini that cuts programming
dramatically. Which saves you a lot
of time and trouble.
The programming you'll never need to
change is part of our hardware. Because we
macroed it in. Yet, we made programmable
the things you'll have to alter from time to time .
Like format changes that normally require
hours of programming. On our Datamanager
you make many changes in one or
two simpl e steps.
That's because its macro-power and data
structure handles data in chunks, as well as
single characters. Which makes every
instruction more effective. And leaves it
handling more data faster than the mini
you know today.
And that's why we call it the Datamanager.
Because it's the business-minded
small computer.
Call us after lunch.

The ISS 728 Storage Control Unit operates up to nine 714's (8 on-line, 1 spare).

There's more: the 728 Control Unit features flexible address selection, in-line diagnostics, plug-toplug compatibility with the IBM selector channel.

Together, they comprise the first system

This is true because the 714 Disk Drive

To the Editor:

issue of MODERN DATA, regarding
SDA (Source Data Automation) and
its impact on systems. Three words in
that article, however, make me take
p en in hand: "fourth-generation concept."
SDA is more like a first (possibly
second)-generation concept that is
finally comjng of age. What with the
new equipment being offered, the
potential is tremendous. But ten years
ago the U.S. D epartment of Agriculture conducted a seminar on ADP in
which it said : "Source Data Automation (SDA) simply means applying the
techniques of automation to the source
areas-where information begins."
The impetus of new equipment will
definitely provide the heavy impact he
has indicated.

I agree wholeheartedly with Mr.
Feidelman's article, in the March, 1970

Russell A. Meier
Lexington, Mass.

I have just read Mr. Feidelman's
article, in the March, 1970 issue of
MODERN DATA, onSDA. The
article is enlightening in that I have
not previously read nor heard of SDA.
I will be looking forward to your subsequent articles on this subjectespecially those regarding the, concepts of SDA and the equipment available in this area.

To the Editor:
In the Jan. article; "The Systems
Scene-Tuning For Performance,"
you estimate below 30% CPU efficiency for 360 installations when they
are up. But your interesting question:
"How efficiently do systems run in
general?" was not answered for nonIBM machines. You say "Multiprogramming is like a new toy. . ." and
"IBM has a new Job Stream Management Package that will replace the
engineer deck stacker." Burroughs
B5500s (medium-sized; general-purpose), have b een operating with multiprocessing/multiprogramming as a
normal mode since the early sixties.
All B5500 I/O operations and
memory accesses are done through
multip.]e paths under complete control
of the Master Control Program ·
(MCP), which efficiently handles
more than 7 jobs in the mix simultaneously. Operators are kept busy
loading cards to the pseudo-reader at
card reader speed (for MCP handling) , mounting tapes (for MCP ref20

erence by name), and printing files
from the printer back-up disk.
The MCP handles scheduling, priorities, I/O control, and back-up
(such as the printer back-up disk)
automatically. As far as waiting for
spare parts goes, B5500s are designed
for graceful degradation-if a peripheral, a memory mod, an I / O channel, or even a processor goes down , it
is a simple matter to tell the MCP
what it is missing and it goes merrily
along without that piece of hardware
(a littl e less efficiently maybe, but not
down). Partitions are not needed
since the MCP dynamically overlays
and rearranges core to be most efficient . More core is not needed so often since the MCP automatically utilizes virtual memory on disk. Maybe
some of the 30 percenters should visit
D etroit for some better ideas in
throughput.

To the Editor:
The article entitled "Computer Controlled Data Acquisition Systems" in
your January, 1970 issue contains a
few errors about our PDP-12.
First, alth ough th e article does not
say so, the computer described is our
PDP-12A. There are t wo smaller versions available at a substantially lower
price. The PDP-12A is currently
priced at $29,900.
With regard to the specs , I would
like to make the following corrections:
The sampling rate of A/ D is 50
KHz, not 5KHz as stated. And it is
standard equipment.
The D / A is also standard and h as
two output channels, each of 9 bit accuracy, an d range 0 to - 5 volts.
The statement below the specs
says, "The PDP-12 . . . uses the
PDP-B as a basic computer". This
statement is not correct. The PDP-12
has a unique processor and is not a
derivative of any other computer, including the PDP-8. It has th e capability of executing two different order
codes, namely the PDP-B and LINC
order codes.
The article obviously was beneficial
to our product and company for
which we are grateful.

To the Editor:
In the January, 1970 issue of your
magazine, there was a discussion of
the Interplex time-sharing system
(The Interplex System 1). In that article, it stated that the system was the
Our
least
expensive
available.
FOCAL Language is much like their
BASIC, and in fact, might be more
versatile. A four-user FOCAL system
costs $22,700. The price of the sevenuser system is $41,500.
Dennis C. Goss
Digital Equipment Corp.
Editor's Reply: DEC is justified in
chastising us for the error. The sentence Mr. Goss refers to should have
been worded: "It (the Interplex System I) is, however, the least expensive BASIC time-sharing system
currently available." FOCAL is a simplified JOSS-like language; the perstation cost of a PDP-8 FOCAL system can run as low as $5,300,
inCluding Teletype terminals.
The article on the Wang 3300
BASIC time-sharing system (MODERN DATA February 1970) was
based on information released after
the Interplex article was printed. A
Wang 3300 four-Teletype system is
priced at $21,250.

To the Editor:
In your January, 1970 issue, you featured an article under the title of
"ICL's Problems." I would like to
draw your attention to the errors of
fact contained in the article.
1. You stated that the British Government had nationalized the U.K.
computer industry, represented by Inernational Computers Ltd. (ICL) .
MODERN DATAl April 1970

ICL is not now, nor ever has been,
nationalized by the British Government. I assume that your reference
implied that the British Government
has both a majority shareholding, and
control, of the company's operations.
Neither is the case. Both English
Electric Ltd. and Plessey Ltd. hold
single ownership blocks of shares substantially larger than the British Government's 10.49%. Additionally, individual shareholders, and banks and
financial houses, each hold larger
share blocks than the Government.
The British Government has one
nominee director (out of 12) on the
holding board, and none on the operating company board.
2. You stated that one of the companies which merged to form ICL
was International Computers and Tabulators (I.C.T .)- "a former Ferranti
subsidiary." In 1963, I.C.T. took over
the computer department of Ferranti
Ltd., leaving Ferranti as an entirely
separate electronic and electrical engineering company. Neither company
has ever owned or controlled the
other.
3. You refer to the International
Reorganization Corp. (I presume
you mean Industrial Reorganization
Corp.) and the Ministry of Technology combining the interests of the
merging companies. The initiative for
ICL's 1968 merger came from I.C.T.
and English Electric Computers and
the negotiations were between the
main shareholders. The British Government merely "blessed the wedding" with funds for R&D in exchange for a minority holding.
4. Your comment that the Ministry
of Technology "retained" 10% of the
shareholding implies that they had, all
along, had holding in ICL. As I have
pointed out, this was not the case.
5. ICL does not have a "conflict of
interests" with our component suppliers. ICL has always, as matter of
policy, freely bought components
from the best available source to ensure the high quality of our product.
This policy still stands.
6. Finally, you refer to ICL's "only
moderate success." In the first complete company year since the merger
(September, 1968 to September,
1969 ), ICL's world-wide results were
as follows: Turnover up to 25%;
Sales up to 40%; Pre-tax profitability
up to 47%. Our first quarter results
for the current year continue the
same trends.
We do not consider this performance "only moderate success."

Editor's Reply: The news item to
which Mr. Dodgson refers (ICL's
Problems-po 36) was based on information contained in a report transmitted from the U.S. Embassy in
London. MODERN DATA erred in its
use of the word "nationalization,"
which was "rationalization" in the
text of the report. W e did not state
that "one of the companies which
merged to form ICL was l CT," but
we accept Mr. Dodgson's statement
that "neither company (lCT or Ferranti) has ever owned or controlled
the other." Mr. Dodgson's third and

fourth points are matters of interpretation. However, we did not mean
to imply all that seems to have inferred. Mr. Dodgson's fifth point refers
to ottr mentioning the possibility of a
conflict of interest. Finally, we did
not say that lCL had "only moderate
success," but 'Only that it had "problems." Certaitnly IC L is no different in
this regard than · any other company_
We accept the impressive performance figures submitted by Mr. Dodgson as an indication that lCL is solving its problems with considerably
more than "moderate success."

A Newsworthy Compendium of How EAI Hybrid, Digital and Analog systems help make a complex world relatively simpler.

KlIPIBG PACE
WITHDAC

Except for things like money, martinis and marriage, which occur in meaningful
and memorable increments, we live for the most part in an analog world. In an
effort to quantify and control this variable ambiance, digital techniques, some
marvelous, some complex, have been devised . In industrial control, a large number
of analog signals of varying value and mode have to be acquired, conditioned,
converted, processed, and the resultant data-- digital, analog, or both-- analyzed
for purpose of increased control or wisdom. EAI's experience in this begins,
appropriately, in the beginning . A quarter-of-a-century's worth of analog-signal
acquisition and conditioning. Now implemented with our proven, dependable EAI 640
digital computer in a number of basic configurations and with a number of useful
peripherals . Together with flexible software that includes standard programs and
routines, the 640 provides the digital interface to the analog world of measurement
and control. We call the whole thing our PACE Industrial D~ta System. For detailed
dissertation on its problem-solving cap~bilities, address "DAC", Dept. 206S.
Money, martini or marriage problems need not apply.

WHJ:H TO
AUTOMATE
YOUR GCS

With the conviction that the dollar sign is not the least important symbol
used in engineering, we've completed a cost analysis of when one should consider
automating a GC installation. Very conservative estimate shows one technician
earning $8400 can handle four GCs. This works out to $2l00/GC/year/shift. When you
have 8 GCs in operation, you must seriously consider installation of an EAI PACE
system . Equally conservative estimate yields PACE cost of $2247/GC/year figuring
5-year amortization period, for 8 GC system. And savings increase rapidly beyond 8
GCs. Savings realized from increased efficiency of chromatographer, full 3-shift
utilization of GCs, reduction of human error, of system downtime and of delayed
analyses have not been taken into account. Nor increased benefits of getting
analysis in a more reliable format. Get a copy of this comptroller-convincing cost
study; write "GCost", Dept. 206S.

CULPRIT (CULL and PRINT) is the first of a new
class of software. Think of it as a report utility. The
concep t has been used only rarely befo re and never
with the tremendous versa tilit y of CULPRIT.
If you've been considering the use of any kind
of report generator and informa tion retrieval system,
you're thinking in the right direction. But beginni ng
today, any th ing you might have loo ked at is
woefully out of date!
Many report genera tors can produce only one
report from one pass of the data file. Oth ers produce
a Cobo l program which mu st be compil ed, link edited
and run before they produce a repo rt. Some even
have both prob lems. That 's Model T designing!
CULPRIT is a parameter-driven program. No
compiling neede d. Th e program is kept on the core
image li brary like a utility an d produces a report as
d irec ted by th e parame ter codi ng. Highly efficien t,
il produces man y reports (up to 99) w ith a s ingle
pas s a nd ca n ex tract from multipl e input fil es.
CULPR IT requires fro m 1/ 10 to 1/ 40 th e normal
codi ng time. This means th at the most juni or-level
programmer can reques t and get a simp le one-time
report in minutes. Or many complex reports in one
pass ... with just a few hours of coding . Not weeks.
Hours ! But fast reports are not all new CULPRIT
ca n do for you .
New Sys tems : When yo u design a new system,
how much of it is made up of report editing pro-

grams? Half? A third? Then you can put your new
system on the air nearly one-third to one-half sooner
by simply pluggi ng new CULPRIT into the system to
h and le th e reporting requi rements. You not only
save programming time, but the machine time
usually need ed for debugging this part of the system.
Process ing speeds are close to tb ose for welldesigned and laborious ly hand-coded programs.
Remember ... this isn 't an ordinary report genera tor.
You just load and go.
Features : CULPRIT has multi-line out put for
address la bels, notices, etc. Other options include
header variables; multiple-lines in headers , detail
and totals; separate ly specifiab le total lines ;
calcula tion ability on both detai l and tota l levels;
use of mnemonics for working fie lds; and many
others. Output may be prin ter, punched cards, tape

The Printer.
It's made especially for the mini- or midi-computer and
CRT terminal user who can 't stand the inefficiency of
a 30 line-per-minute impact printer.
Or the cost of a high speed printer.
The new MATRIX SERIES non-impact printers from
Versatec fill an important gap in the EDP and communications field.
MATRIX 300 delivers 400 characters per second for
$5,500.
MATRIX 600 doubles the speed for $6,700.
You can list your most complex program in minutes.

Routine programs are handled in a jiffy.
The printer is silent, highly reliable , and produces
records of excellent quality. Graphics capability is offered. MATRIX SERIES printers and plotters also find
applications in time sharing, batch processing and nonEDP communications.
Output is printed as perfectly formed 5 x 7 dot-matrix
characters in 80 columns on 8V2 inch wide paper.

The System.
Every important breakthrough has its revolutionary applications.
The LSI circuit made possible a " computer in a
suitcase. "
The MATRIX electrostatic printer has created the
MUL TIPLUS hi g h speed distribution system.
Briefly, here's the story.
Unlike impact printers , the greatest cost in a nonimpact printer is the electronics and not the printout
mechanism . Thus, MATRIX slave terminals can be made
available for $3 ,000 each or less depending on quantity. The master printer, alone , contains most of the
electronics.

With a MULTIPLUS system a newspaper can get
copies of a fast breaking story direct from the wires to
a dozen desks - simultaneously! And economically.
A large production facility can reach any or all corners of its plant without using a messenger. Ditto a

light work with the 417 . For you .
As for it: shake it , bounce it, bump
it , stand it on end . It st ill records
as accurately as if you 'd lugged a

seven channels, I RIG compatible .
Inside its standard case (15" x
14" x 6" ) or the rugged environ mental case shown (17" x 15" x
7" ) , beats a heart with 200 Hz to
100 KHz d i rect frequency response. (FM frequency response
is DC to 10 KHz.) In either case, it
fits under an airliner seat.
The stoic 417 needs little atten tion -fewer adjustments and less
maintenance than any other portable recorder . For power, it normally needs only 13w. And that
can come from its self-contained
battery. Accessories can use it on
any power: 12 to 28v DC, 110 to
220v AC , or 50 to 400 Hz.

MODERN DATA l April 1970

Undoubtedly your first reaction to us will be a sense of irritation
at a certain loss of revenue.
If that's your only reaction, you'll be making a big mistake.
Allow us to explain.
We, the Dynelec Systems Corp., have developed a unique approach to data communications that is, by conservative estimate,
400% more efficient than that used in other systems now operating.
With our equipment, up to 120 mixed-speed data terminals can
be acconlmodated simultaneously over each voice-grade line.
This is 4 times as many as in any other system.
Which means that multi-location data communications customers
will be able to concentrate and send far more data, more economically,
to and from their computers than they ever could before.
But substantial reductions in leased line and modem costs alone
are only part of the story. Great additional savings are made through
use of our equipment.
For example, our basic, low-cost
communications multiplexor,
the TM DyneCoM 70W, grows as
customer needs grow.
Becauseofitsmodulardesign,
.........
a user can start off inexpensively with as
few as 2 channels and plug in additional circuit boards to
handle up to 64 mixed-speed terminals.
Other 70W features include the unit remaining operative despite
channel failure, simple visual diagnostics, self-service maintenance,
up to 4 speeds and any code, and automatic speed selection.
Total annual savings can easily exceed $100,000.
The Dynelec approach opens such vast new vistas in data communications that they far outweigh any AT&T revenue loss that
results from the savings we can help customers enjoy.

OHIO BELL WITHDRAWS PROPOSED TARIFFS

TELEPROCESSING FOR SYSTEM/3

The Ohio Bell Telephone Co. has withdrawn its proposed new tariffs against information systems using
Ohio Bell's access lines to communicate data. The
telephone company referred the proposal to AT&T
for further study. Th e Association of Data Processing
Service Organizations (ADAPSO) and the Business
Equipm ent Manufacturers' Association (BEMA) had
protested the proposal several months ago when it
was originally submitted to th e Ohio Public Utilities
Commission for approval. Since the new charges
would apply regardless of wheth er the transmissions
originated or w ere terminated at out-of-state locations, ADAPSO and BEMA argu ed that th e proposed
intra-state charges w ere also charges against interstate service. ADAPSO had filed a petition to that
effect with the Ohio Public Utilities Commission,
claiming that the proposed tariffs w ere discriminatory
to data processing organizations and, in any case, beyond the jursidiction of the Ohio P.U.C.

IBM has announced a communications adapter for its
new System/ 3 business computer that will enable it
to ex change data with remotely-located System / 3s
and most System/ 360s. The adapter will provide an
a utomatic answering capability and, optionally, an
automati c di al-up capability under program control.
Also optional - a programming support feature for
use with RPG II that includes a fill-in-the-blanks
specification sh eet through which the user can describe hjs communication tasks. This information is
then punched into the system's 96-column cards and
fed into the computer along with other RPG II instru ctions which comprise th e user's application program. The adapter, which will utilize an IBM-developed binary synchronous transmission technique to
transfer EBCDIC or ASCII data at rates up to 50,000
bps, will rent for $265 a month, or may be purchased
for $12,985. An adapter attachment is required a t $35
a month , or $1,725 purchased. The RPG II telecommunications feature will b e licensed for $35 a
month . Availability is scheduled for th e first quarter
of 1971.

MATCHING SERVICE FOR DOGS
A computer matching service for real dogs has been
formed to assist people having trouble finding suitable mates for th eir pets. Bruce Kusens, an industrial
engin eering student at the University of Miami,
leases time from th e university's computer center for
his "doggie match" service. Local kennels provide
him with candidates. Mr. Kusens said that although
his service has produced many su ccessful matches, it's
"not exactly a howling success."
ADAPSO WINS COURT DECISION
The Association of Data Processing Service Organizations , Inc., (ADAPSO) won a reversal on the issu e of
whe ther data processing companies could sue on
claims that national banks are ill egally competing
with them. The 6-2 decision, which reverses a previous decision of the U.S. Court of Appeals, p ermits
ADAPSO to pursue its case against the American National Bank of St. Paul and the U.S. Controller of the
Currency. ADAPSO instituted suit against the American National Bank of St. Paul in 1967, challenging a
1966 ruling by the Controller that authorized banks
to provide EDP services "incidental to banking."
ADAPSO filed in the Federal Distri ct Court in Minneapolis, seeking to have the St. Paul bank d esist
from offering these services and asking for a ruling
that the Controller's authorization w as ill egal. The
District Court ruled that ADAPSO lacked standing to
sue and dismissed the case. The Association appealed
the decision to the U.S. Court of Appeals and was
again denied. The Supreme Court first heard the argument of the Association's attorneys in Oct., 1969.

RELIGIOUS INFORMATION NETWORK
DSI Systems, Inc. of Rockville, Md. is reported to
have been awarded a $1 million contract by the
Christian Research Institute (CRr) of Wayne, N.J. to
provide DSI's data retrieval service to religious institutions across the country. The CRI-DSI system
would link a vast data base of cross-referenced religious information to termin als located in colleges,
biblical institutes, and seminaries. Queries initiated
by the terminal operators regarding the whereabouts
of selected portions of religious texts would b e answered in th e form of a reference to one of many
microfilm cassettes stored at the terminal location .
Placing the cassette in th e terminal would automatically cause the relevant text to b e retrieved and displayed for viewing. A strip printer would output
changes or special notes which pertained to the text
b eing view ed. DSI currently has orders for nine terminals, but expects to have 300 more installed for this
purpose by 1975.

Speaking before a meeting of the Chicago Securities
Analysts, Leon Staciokas, president of Digital Information D evices, Inc., pointed out that p eripheral
equipment sales by independent manufacturers approached $3 billion in 1969. Mr. Staciokas predicted
an annual growth rate of 30%, which would bring
this figure to $7 billion by 1975.

AMA IN FAVOR OF AMHT
Dr. Gerald D. Dorman , President of the American
Medical Association, said that the AMA favors the
integration of Automated Multiphasic H ealth Testin g
(A MHT ) into the existing medical care system. Dr.
Donnan said that AMHT is neith er design ed to, nor
capable of, replacing th e evaluation of a patient's
health by a phys ician . However, he hailed it as an
"effective new technique for providing physicians
with data which ca n aid th em in making more rapid
and accurate diagnoses, th ereby improving th e delivery and quality of hea lth care services."
Automated Multiphasic H ealth Testing is th e term
applied to systems which combin e automated equipment and co mputer technology with clinical tes ts and
procedures to meas ure an individual's h ealth statu s.
This information is th en integrated by th e physician
with th e p ati ent's history and his physical examination to evalu ate th e p atient's health status .
Dr. Dorman, whose organization represents th e majority of th e na tion's physi cians, made his statement
in a paper delivercd at a symposium on Automated

INTERNATIONAL NEWS
SOUTH AFRICAN INSTALLATIONS - The Republic of South
Africa is expected to have 520 computer installations this
year, says the U .S. Dept. of Commerce. By 1973 as many
as 1,000 computers may be installed in the Republic. Since
no significant production of computers in South Africa is
considered likely within the next five years, the Republic will
have to rely on foreign suppliers for its computer needs. Six
such firms - IBM, Internati ona l Computers, Ltd ., En g lish
Electric -Leo -Marco ni, Burrough s, NCR, and CDC - currently
supply some 65 percent of the total South African market.

COMPUTERIZED TRANSPLANTS - Hospitals in Montreal,
Canada, are cooperating in a clearing house for possible
donors of organs that can be used for transplants . UPI
repo rts that the new organization, Metrotransplantation,
seeks to match donor and recipient according to organ t issue similarities. Possible donors and recipients are " tissue
typed" with the information being fed into computers for
fast future reference .

MALAYSIA TOP SE ASIAN MARKET - The market for computers in Malaysia is bigger than any other Southeast Asian
country, the Bernama news agency reports . Walt J. Milas,
Far East Manager for Mohawk Data Sciences Corp., believes
this is due to " the rapid industrialization program that the
government is currently pursuing." The number of computers used in Malaysia is likely to double in the near future,
he believes.

COMMUNICATIONS COMMON MARKET - Robert W. Sar·
noff, Chairman and President of RCA has called for the
creation of a global "Common Market of Communications"
that would transcend narrow national interests. He warned
in a Paris speech that failure to act promptly on a common
global communications policy could result in chaos and cost
the nations of the world at least $100 billion a year over the
next decade.

HONG KONG OUTLOOK - Except for computers and the
American-dominated components field, growth prospects for
sa les of U.S. electronic products in Hong Kong "a re cloudy"
because of heavy competition from Asian producers. The
American Consul in Hong Kong reported that the electronics
industry is the third most important export earner for the
Colony. Assuming the U .S. demand (about 75 % of production) continues, it is expected that the industry will grow
despite a tight labor market and mounting shortage of factory space. A major export is computer memory arrays,
which showed the best component performance in 1968
with exports ris ing 26 percent to $13.8 million.
Hong Kong's market for computers is small but expanding. Imports of EDP equipment totaled $ 2 .5 million in
] 968 - up 54 percent from the preceding year. U.S. products amounted to close to $2 million of this total. While
computer users thus far have been limited to large banks
and industrial concerns, Hong Kong 's increasing economic
sophistication suggests, the American Consol said, "more
sales growth in the future, particularly in time-shared arrangements."

GERMAN POST OFFICE - Th e German Post Office has gone
into the time -shari ng business. To gether with two leading
computer manufacturers - Siemens AG and AEC Telefunken - it has fo unded Datel GmbH in Munich . Although
the Post Office has made its telephone and telegraph faciliti es ava:lable for DP applications in the past, the new company will supply complete time-sharing services, including
terminal facilities and software. Datel GmbH seems to represent both an attempt to assist German businesses in takin g advantage of computer technology and the involvement
of the Post Ministry in the efforts of the German-owned
computer industry to ga in and hold a major share of the
German market .

GE OVERSEAS - General Electric 's computer operations
overseas in 1969 "made rapid strides toward profitability, "
accord ing to Hilliard W. Page, v.p. and gro up executive for
GE ' s Information Systems Group . " GE Information Systems
Italia (GE I.S .I.) is profitable now" and the French affiliate,
Bull -GE " very soon will be. " Installed value of GE information systems equipment world-wide is now more than $1.3
billion . GE believes the world market for on-time -s haring is
expected to reach $1 billion by 1973, and double that by
1975. The company estimates that its service network will
consist of more than 75 systems serving 100,000 time-sharing users in 21 countries on five continents before 1971.

AUSTRALIAN MARKET - By mid-1969, there were 813 dig ital computers in Australia and an additional 222 on order,
reports the American Consul in Sydney. Nearly two-thirds of
the top 800 Australian firms have not yet been committed
to the computer age.

QUICKLY AROUND THE WORLD
Computer Data Enterprises , I nc ., Jenkintown, Pa ., a software and faciliti es management corporation, has entered into
an association with INTECH Australia, Ltd., Melbourne, an
on-line systems specialist. They plan to begin their efforts
by implementing passenger check-in systems for several airlines and airports in Southeast Asia .
Collins Radio has received a lease contract from the Mexican Government for a Collins C-System which will be used
initially to process all motor vehicle registrations and re lated tax functions in Mexico.
A new $1 million Univac real-time computer system, con·
tracted for by the Totalisator Agency Board (TAB) of the
Australian Capital Territory (ACT), will provide bettors on
horse and dog racing events with better service when it
becomes operational in 1971.
IBM has introduced its System/3 computer in Germany and
expects to have it ready for sale by April or May. This
makes the first time IBM has quoted its German customers
separate prices for hardware and software.
When top international skiers rush down the ski-runs of the
Grodnertal , in the Italian Dolomites, the representatives of
the press will be instantly provided with comparative speeds

Harold V. Semling, Washington Editor

DC DATASCAN
TECHNOLOGY TRANSFER - Senator Jennings Randolph
(D.-W.Va.), chairman of the Senate Subcommittee on Science and Technology, believes that the Federal Government has a responsibility to see that small businesses participate fully in utilizing new technologies developed at
government expense. He pointed out that a third of the
R&D contracts go to about ten corporations, while the entire small business community is awarded only 3 %%. The
result is that the advantages are highly concentrated. Sen .
Randolph 's subcommittee has twice called for a coordinated federal technology transfer mechanism, but, the
W.Va .. Senator said, " there has been no visible response to
these initiatives, and, in fact, existing programs have been
sharply reduced ."

AIR TRAFFIC CONTROL - " A maximum commitment of
American management and technological genius is essential to avoid a disastrous breakdown in the nation's air
traffic control system," Rep. Jack Brooks (D.-Tex.) warns .
He urged "the full resources of the nation and the cooperation of all segments of the aviation industry to support FAA
efforts to perfect the air traffic control system the nation so
desperately needs." Hearings by the House Government
Activities Subcommittee, which he chairs, indicate that
FAA' s new computerized air traffic control system is 3 to 5
years be hind schedule due to fund shortages, technical
problems, and inad e quacies in contractor support.

NEW TELECOMPLAN - President Nixon proposes to establish a new Office of Telecommunications Policy in the
Executive Office of the President, abolishing the office of
the Director of Telecommunications Management . The plan,
which automatically becomes effective unless disapproved
by one House of Congress, is considered as a move to
centralize government telecommunications activities. Under
the plan, the new office would have responsibilities that
would include the development of government-wide stan dards for equipment and procedures, recommendations to
the Budget Bureau concerning the funding of communications systems and R&D programs, and preparation of
guidelines for the most economical procurement of federal
telecommunications services.

NSF COMPUTING ACTIVITIES - The Federal Budget for
F.Y. 1971 includes $511 million for the National Science
Foundation, of which $4.5 million will be used for computer
resources "with marked emphasis on the development of
multi-institutional centers to serve major research users and
innovative cooperative approaches to meeting educational
and research computing requirements ." The level of support for computer-oriented research and educational activities will be sustained at $10 .5 million, which will enable the
NSF to award approximately 175 grants for projects in
computer science and computer-assisted instruction.

CONSTITUTIONAL RIGHTS - Senator Sam J . Ervin (D.N.e.) has called upon Secretary of the Army Resor to explain reports of an Army data bank on civilians . Sen . Ervin,
who is chairman of the Senate Constitutional Rights Subcommittee, said he has had many complaints about the
data banks . " The Army," he believes, " has no business
operating data banks for surveillance of private citizens;
nor do they have any business in domestic politics." He
wants to know by what le gal authority the data is gath ered and what re levancy the files have to the responsi bilities of the Army. The Se nate Constitutional Rights Sub committee is directing similar types of queries to other
federal agencies in an effort to find out how many data
banks containing information on the pe rsonal lives of indi viduals have been developed so far, and whether con stitutional rights are being respected in the construction of
government information programs.

MIGRANT CHILDREN - Seven states (Arkansas, Colo rado, Kansas, Missouri, New Mexico, Oklahoma, and
Texas) will soon be testing a new data system designed to
enable school and health officials to trace the frequent
movements of migrant children. All 48 mainland states will
eventually be phased into the system . Because migrant children move so frequently it has been difficult to keep track
of their whereabouts, educational levels, and special
needs . Extensive debugging is being done in Little Rock ,
Ark ., where the Uniform Migrant Student Record Transfer
System is being developed under a contract between the
U.S. Office of Education and the Arkansas Dept. of Education. The new system is expected to b e ready by July 1, at
which time the seven states will be hooked into the system
on a pilot basis. Other states will join the system after 6
months .

Datawaft's Software Creed:
anounee

of hard-wiring
is worth
a pound of program
"Hard-wiring" is a nickname for
all those clever circuits built into
a computer that automatically
transfer, combine, store and fetch
information. "Software" is a nickname for the man-hours of headwork you have to suffer through
to make up for the gaps and omissions in the hard-wiring.
Datacraft's DC 6024 general purpose digital computer has the best
hard-wired instruction set ever designed into a 24-bit machine. No
side-stepping the issue here. Our
engineers began designing the
6024 with programming in mind,
and finished the job satisfied that
customers would never again
curse the word "software."
The DC 6024 assembler program
works on 120 generiC types of
instructions, and recognizes more
than 500 actual operation codes.
Our standard instruction set in-

byte manipulation , algebraic and
logical compare, two methods of
subroutine entry, an extensive set
of one-cycle immediate operand
instructions , an extensive set of
shift instructions, a set of interrupt
instructions that allow control of
up to 24 interrupt levels with a
single instruction, and singlecycle I/O transfers.

cludes a number of innovations
for 24-bit computers that take a
lot of the sting out of day-to-day
programming routines. Only Datacraft provides everyone of these
convenient instructions : doubleprecision arithmetic, square root,
multiple register load-and-store,

We can't afford to send out many
DC 6024 computers as free samples, but we do have a pocket-size
summary of our instruction set. It
will tell your programming people
all they need to turn them into
Datacraft fans for life . Send us a
request on your letterhead, and
we'll send you a copy. If our low
pri ces and swift del ivery don't
convert you into a customer, our
programming advantage will.

Never send your software
to do a hard-wire job.

FAST-FOOD STOCKS

Stock Ta lk is a regular monthly column p repared by Spear
& Staff, Inc. especially fo r MO DERN DATA. Inves t me nt questio ns of genera l interest will be answered , as sp ace pe rmits .

Address questions to:
Dept. RAS

As American culture has progressed further and further
away from the stay-at-home style, and as the pace of midtwentieth century life has quickened, the trend toward con venience products has pushed the fast-food industry to
near the top of the list of the nation 's fastest growing markets . Each year a greater proportion of personal income is
classified as " discretionary spending power," and an everexpanding part of this pocket money is being spent to feed
the public away from home and usually on the run.
Fast-food service outlets range all the way from completely " take out" stores to " eat in" units, with a myriad of
variations in between _ Usually these establishments offer a
limited or single -item-centered menu, for reasons of market
impact a s well as physical simplicity of output . In order of
predominance, hamburgers are the favored item (35 %)
followed by ice cream and fried chicken (roughly 20 %
each ), and hot dogs, donuts, pizza, and roast beef-steak at
about 4 % each.
In the last few years there has been an explosion of
franchising in virtually every fast-food specialty and, until
1969, the stocks of these publicly-held entries were selling
almost as fast as the hamburgers and donuts themselves .
By last spring however, a combination of tight money and
analysts' fears of over-saturation had begun to take its toll
on the group 's stocks .
Celebrities in all phases of public life were lending their
names to a new chain _ Joe Namath, AI Hirt, and Johnny
Carson are but a few _ The less established chains have
seen their stocks skyrocket and then often plummet to half
of the original offering price _ The industry giants have
moved in sympathy although less sharply, of course _
Basically, industry analysts feel a period of digestion is
in order, one which will probably see a number of smaller
chains fading out or being eaten up by bigger names.
Despite the discomfort among those directly hurt, the overall industry will continue to grow a pace _ For the present, it
70

seems wise to concentrate commitments in well-established
companies rather than to try to pick the long-shot recovery
candidates.
The following is a review of three of the represe ntative
fast-food companies and their stocks.
Friendly Ice Cream Corp. operates a chain of ove r
200 ice cream and sandwich shops in central New Eng land, New York, and New Jersey. Each shop offers a standardized menu featuring hamburgers, soups, fountain specialties, and a variety of ice cream dishes in many flavors.
The company has sought to make " Friendly's" a household
word by providing predictably friendly, speedy service in
cheerfully decorated , spotless surroundings. Effective control over all aspects of the operation has been established
through a non-franchising policy and heavy emphasis on
the provision of in-house services from the company headquarters in Wilbraham, Massachusetts _
The stock of this company was first offered to the public
in August, 1968 at $28 per share and was split 2-for-1
twelve months later _ Of the 3,355,000 shares outstanding
after the split, only about 15% are publicly held, with the
balance being held by S _ Prestly Blake and Curtis L. Blake
(combined , almost ¥.J) , and by various other management
and shop managerial personnel.
In November, the company filed a registration for a
570,000 share combined offering, including 150,000 shares
for new financing. The stock has reacted to this and to th e
general market decline by slipping from its 1969 high of
36 bid. However, management capability plus tight control
of completely non-franchised operations should enable the
company to out-pace the industry and avoid the possible
pitfalls envisioned for the lesser competition _ Shares are
attractive for long-term participation in an expanding field .
Probably the single most established name in the franchising restaurant field is McDonald's Corp_ Presently
there are over 1200 outlets in operation and plans call for
the opening of at least 100 annually through 1972. About
85 % of the outlets are independently-operated franchises
on which the company receives rentals base d on a percentage of sales, with a fixed minimum annually_ Because
of the nationwide scope of the business (forty-eight states
plus Canada, Puerto Rico, and the District of Columbia ),
the company does not attempt to supply food items or
sup-plies, but has maintained an extensive inspection program to insure high quality _ The company is also creating
and staffing an international operations division which is
expected to open its first restaurant outside the United
States in 1971. Revenues have risen 10-fold since 1962 and

earnings have grown consistently at 30%-40% per annum.
1969 net should be $1 .10-$ 1. 15 per share versus $0 .83 in
1968 . A further gain to $1.40 is projected for 1970. While
the stock is not cheap on a price-to-earnings ratio, it probably will continue to command a relatively high multiple
based on uninterrupted growth for e seen in next several years.
Anoth e r large fast-food franchiser is Kentucky Fried
Chicken . Th is company has developed a system of over
2700 units (largely franchisee-owned) specializing in the
preparation and sale of its famous " Colon e l Sanders' Rec ipe Kentucky Fried Chicken ./I Kentucky sells operators virtually every raw material and equipment item except the
chicken, which is locally supplied for re asons of conven ie nce and health . The chicken is prepared in accord ance with a unique secret process involving a preci se combination of heat, pressure, and working ti me.
In April , 1969, the co:npany acquired, for common stock,

The company estimates that full-year 1969 sales should
climb to $160 million with per share earni ngs reaching
$1 .25. Prospects for further gains in revenu e s and net in
fiscal 1970 should continue to earn the stock its hi storically
high price-ta-earnings ratio. Shares represent an attractive
growth speculation for the long pull.

INCOMING MAIL

QJ I am interested in Bunker-Ramo stock. I would ap preciate your opinion on this company's future . M. B.
A) Bunker-Ramo has been unable to buck the market
downtrend despite an apparent earnings turnaround. For
the nine months ended Septemb er, 1969, share earnings
rose to $0.41 on a 6.4 % increase in sales. Full-year earnings are expected to approximate $0.53 per share versus
$0.35 in 1968. The combined companies derive over 50 %
of sales from electronics components and the remainder
from computer-based systems, numerical controls, and
d ee p-pile fabrics . Th e company holds contracts to supply
terminal equipment for the Big Board's new Block Automation System and to build and operate a new quotation
system for O -T-C securities similar to the alre ady established Telequote System . In February, 1969, one such system be came operative and another is expected to in 1970.
Competition is increasing in some of BR's important product
areas. However, a combination of earnings recove ry and
potential for th e company's new er systems gives the shares
long-term sp ecu lative appeal.
QJ We have shares of Phillips Petroleum. Would you
advise us to sell? What is the company's future outlook? f .B.
A) Despite an improved third and fou rth quarter, Phillips
Petroleum reported a slight decline in full-year 1969 earnings to $1.73 from $1.78. W eak prices in some segments
and plant start-up costs were adverse influences and narrowed profit margins for much of 1969. However, future
prospects are e ncouraging. The company has one of the
strongest positions, among the major dom estic oils, in
natural gas produced p er common share. Thu s, an inc rease
in natural gas prices wou ld greatly benefit Phillips, and with
the recent reduction in the depletion allowance, the FPC
is hard-pressed by the industry to do just that. Phillip's
Artic Slope holdings could boost future ea rnings. Significant output from this area would lesse n or even abolish
the company's costly crude purchases presently requir e d to
meet the d emand of its West Coast marketing territory. In
the meantime, the obj e cti ves set forth by the new president may spark a reawakening for Phillips: exploration and
profits are expected to be stressed. Shares may be held.
QJ I have a substantial number of shares in Diversified
Growth of the Anchor Group . There has been a shrinkage
in value. Are they worth holding? D.F.
A) Diversified Growth, like many of the other speculative
growth funds, found the going quite rough in the 1969
market slump. In fact, for the first time in 6 yea rs, this fund
suffered a loss - 16.4%. While this drop in value is somewhat larger than the average decline of all growth funds,
gains in prior years amply offset this. In rising markets such
as 1967 and 1965, your fund achieved a 52% and 39 %
gain, respectively. A five-year record, 1964-1969, for Diversified Growth shows a total gain of 78 %. Although this
mutual fund has an above-average growth rating, its speculative portfolio is susceptible to market downturns. Given
an improved market climate, this fund should work out. •

Introducing Delta Data Systems' TelTerm. The only video
terminal that can display over 100 lines of data on the screen.
TelTerm is a totally new concept in remote computing. Its storage and
display capability of over 100 lines of data puts it a giant step ahead of all other
video terminals. No video display on the market can show as much data.
Because no video display has the up and down paging feature, exclusive with
TelTerm.
And 80 characters per line on 27 lines. Formatting that allows fixed and
variable data fields. A blink feature that flashes data on the screen twice per
second. Data tran smission speeds to 9600 baud asynchronous, 4 million bits
per second synchronous. A memory capacity of 2500 characters. Plus a
separate numeric pad on the keyboard.
And all that capability is yours in three TelTerm models. All are desk top
units with keyboard, display, and control electronics in one package. And
they're designed for applications like time-sharing, reservation systems, communications and information systems, inventory control , process control. Each
TelTerm model has its own special capability and an unbeatable price, like
TelTerm 1. $90 amonth. Our Teletype Replacer.That rings a bell when the
64th character on a line is entered. TelTerm's low price and high speed for receiving and displaying information puts it generations ahead of teletype.
TelTerm 2. $100 amonth. Our Block Mode Transfer Display. Has an editing
feature that inserts and deletes lines and characters. Conversation mode. An

Datatron sales in microelectronic testing equipm ent and
services should parallel th e sales growth of miniaturized
components and the increas in g d emand for compon ent
pre-screening. The firm on ly recentl y entered into production and marketing of IBM-compatibl e disk packs. Rega rding this, Purcilly says, "our sales in this a rea alone should
reach an annualized rate of $3 million b y June 30 . Th e
n ation al disk pack market is an estim ated $300 million."
Purcilly says Datatron plans on becoming a large COl'pOration through internal growth and acq uisition of other
electronic manufacturin g companies. H e intends such
growth not to be conglom erate but "congeneric," meanin g
all companies and products interrelate in one general fi eld .
Wh ile governm ent sales totaled 70% in fi scal 1968, the
company reduced this p ercentage to 46% in fi scal 1969

SOURCE DATA AUTOMATION

SDA: THE CONCEPT AND THE EQUIPMENT
SOURCE DATA AUTOMATION is a mon thl y co lu mn w ritt en by
Law re nce A. Feide lm a n and th e staff of FA IM In form ati on Servic es, Inc . Ques tion s from rea ders on any aspect of SDA will
be answered, as space pe rmits.
Address a ll questions to : SDA, M ODERN DATA, 3 Lockl a nd Ave nue , Fra mingh am, M ass.

machin es required at many installati ons results in high
syste m cost. Furthermore, keypunchin g is slow and relati vely inaccura te, data editing is extremely poor, and the
use of cards as a computer input medium is inefficient.
Fin all y, as a result of SDA, keypun ching now represents an
extra step in data processin g th at can be either eliminated
or red uced.

SDA OPERATING CONDI TIONS

Source data autom ation is a technique for automatically
capturin g data at its source of origin a nd convertin g it into
a particular machine format or code. The essential purpose
of SDA is to elimin a te unn ecessa ry re transcription of data
( parti<.:ularl y f rom punched ca rds) for machin e processin g.
SDA represents a systems des ign approach rath er than a
hardware con cept. Th e design of th e equipment, procedures, and forms must b e specified from user to computer.
There is a need for source data automation in both the
government and industry. Beca use of th e staggerin g
amount of paperwork th at threatens to engulf every business and governm ent agency, cleri cal costs are risin g
drasticall y. An example of this p ape rwork explosion can be
readil y seen in th e government, which uses approximately
360,000 different forms an d prints approximately 15 billion cop ies a yea r. App roximately $60 million is spent to
print these forms , and 20 times as much is spent on the
cle ri cal efforts involved in using th em.
The input of data is a roadblock for data processing
equipm ent b ecause of the relati vely un sophisti cated input
eq uipment used to handl e th e data. Becau se of the high
speed of the compute r and th e relatively slow speed of th e
input equipm ent, the computer is in effi cientl y used.
It is ap p arent th at a revolution in designin g faster input
equipment is alread y in progress . Equi pmen t p resentl y exists that w ill lead th e wa y. But it is important to understan d th oroughl y th e SDA concept, and to kn ow what
equipm ent is available, how it is used , and what b enefits it
provides.

THE CONCEPT

The SDA concept involves the preparation of data and its
conversion into mach in e-readable form in the most
efficien t , accu rate, timely, and economic mann er. The
ideal is to process data automati call y with no manual in tervention. Due to certain environm ental and oth er restrictions, thi s ideal usuall y ca nnot be reach ed at thi s tim e.
H owever, present SDA devices are meant to perf 01111 b etter th an keypunches .
Keypun ching, presentl y the prim e computer input system, requires data to be punch ed on to cards for compute r
input. Little concern for th e actual generation of data is
necessary as long as it can be rea d by th e keypun ch opera tor. Keypunches are plentiful and low in cost. So why
change?
A primary reason is th at the large number of keypunch
84

Th e range of operating condition s applicable to SDA is
extensive and is limited only by the user's ingenuity. The
value of SDA, in add ition to reducing cost and personn el
errors, and in creas;ng computer thr o u ~hput , is to systemize data processin g operations. This data integration process ex tends throughout th e entire inform ation flow of the
company. Specific opera tin g condition s to which SDA can
be b enefi ciall y applied are:
1.
2.
3.
4.
5.
6.

Large data processing input volume;
Short response time requirements;
Excessive data h andling;
Re petition in using some data ;
High personn el requirements for data h andlin g;
Excessive use of computer for in put processing.

SDA EQUIPMENT

SDA equipment varies widely in complexity an d cost. It
covers the gamu t from prepun ched card tags to direct
transm ittal of v'ritten or vocal information t o the compute r. Th e basic types of SDA equipm ent currently on th e
market are described as follows .
KEYBOAHD- TO-TAPE - devices consist of a keyb oard (typewriter or keypunch ), a buffer memory, and a tape
unit ( bas ically magn etic tape or disk ). Source data is reco rd ed directl y on th e tape by keying. In some devices, this
ope ration provides a ha rd copy output as well as a magnetic

mitted directly to the central processing system. Present
optical readers fall into three distinct classes : character
readers, bar code readers, and mark sense readers.
An optical character reader (OCR) recognizes the
actual character directly by its shape. Optical character
readers are classified by their ability to read different
styles of mechanical and handwritten characters. There
are readers for single-font, multi-font, and handprinted
characters. Within these classes, OCR equipment may be
further divided by character set capabilities: numerics,
alphanumerics, symbols, and special functional notations.
Multi-font OCRs, which range in price from $100,000
to $1,000,000, are a recent development and are becoming widely accepted. Single-font readers range in price
from $20,000 to $ 130,000. Numeric handprinted character readers are now being commercially produced by most
major manufacturers. Their usage, however, is still dependent on the quality of text preparation.
Bar code readers "read" a charaoter indirectl y by recognizing an associated bar code which is limited to a numeric character set. Bar codes are printed on paper by
embossed ( usu all y plastic ) ca rds or b y keyboard imprinters. Bar code readers cost less than OCRs and are as
reli able. Their main disadvantage is the requirem ent for
embossed cards or special keyboard imprinters.
Mark sense readers do not "read" characters' rathe r
th ey choose among given ch aracters by detecting ~arks i~
sp eci fi c location s on the paper. Thei r advantages are that
they are highly reliable and low in cost . (Typicall y in the
$20,000 range.) Their disadvantage is th at they are
inflexible due to a requirement for preprinted forms an d
packed formats.
MAGNETIC READERS - read
preprinted magnetic m arks
on hard copy and have been used mainl y by the b anking
indu stry for recording bank ch eck d ata . Th e character set
represented by the E-13B t ype font has been a familiar
part of th e checks printed in the United States.
Although magnetically-encoded documents require
high-quality printing and a highl y-sp ecialized font , they
are relatively immun e to dirt marks and overwriting. Furth ermore, magnetic readers offer better protection again st
forgery th an optical systems.
Magnetic readers have not on ly been used for reading
alph anumeric characters, but for readin g magnetic
binary-coded data. Th ey can read a large amount of such
data in a small area, thus reducin g document costs. Applications are basically in reading preprinted ticket sales data
(e.g., transportation tickets, clothing tickets).
SCANNERS - are used to transmit source data
from a remote location to a cen tral processor which may
be anywhere from a few feet to many hundreds of miles
away. Some devices may be used in conjunction with a
commun ications coupler to transmit data over telephone
lines, while others must be conn ected by cable to a nearby
control unit which sends data from several devices to the
computer.
Most remote scann ers can read standard 80-column
punched cards. Some only read p repunch ed cards while
others will only read marks made by pencil. Some scanners can read documents of many different sizes up to
8W' x 11". Remote scanners, for the most part, read
mark sense Hollerith code. Those which will read characters, essentially remote OCR devices, may take anywhere
from one card. or document up to 500 cards at a time.
REMOTE

PORTABLE DATA RECORDERS - are small , lightweight devices designed for use where it is impossible or impractical
to place a more sophisticated data recording device. They
are of simple construction and very easy to operate. Their
output may be punched cards, paper tape, or m agnetic
tape. Levers, buttons , and dials are used to enter the da ta,
usually anywhere from 1 to 12 characters per entry. All
devices are manually operated. Some are completely mechanical, while others operate on batteries.
DISPLAY TERMINALS - are compact units that display information on the fa ce of a cathode ray tube; data can be
entered from a keyboard or received from a computer.
Most display terminals handle alphanumeric information
only . There are, however, terminals which display graphs
and other complex shapes. These more sophisticated display devices are commonly referred to as "line drawing"
or "graphic" units.
Display terminals can either be connected directly to a
computer I/O chann el or remotelv conn ected via an appropriate controller or adapte r. They require an auxiliary
printer unit in order to provide a permanent (hard copy)
record of transmitted data.

INDUSTRIAL
DATA
COLLECTION
EQU IP MENT - is
typically used for employee attendance recordin g and production and inventory control. There are both transmittin g
and non-transmitting systems, with th e form er b eing more
compl ex and expensive.
A transmitting data collection system consists of remote input stations transmi tting data m essages to a control location. A message might con sist of an employee
number read from a badge, a job number read from a
prepunched card , a unit quantity read in via keyboard,
and a station number which is automaticall v entered under program control. Non -transmitting d~ta collection
equ ipm en t produces (at each station) a record of the
source data on punched cards, paper, or magnetic tape .
CASH REGISTER ADDING MACHINES - record retail sales
information , usually in the form of a journal tape, and
accumulate totals . Sales inventory data can be proccsscd
directly from the tapes.
The Un i-Tote point-of-sale register system is an alternative to the above. In the Un i-Tote system , keyboard-entered transaction data is printed on sales slips and simultaneousl y transmitted to a central location where it is
recorded on magnetic or paper tape . Sales da ta can be
transmitted immediately for processing by the computers ,
which elimin ates the need for tape collection. Furthermore, an optical feature permits an on-line credit centralization ch eck.

Take a lesson
in EDP efficiency
from some
California school kids.
The boy in the picture
isn't one of those computer prodigies.
Yet he routinely prepares documents for computer processing. With
the simplest data-entry
device imaginable: an ordinary, everyday pencil.
A unique machine reads those documents
(they're tests) and automatically translates
the pencil marks to computer language. The
machine also automates attendance recordkeeping and report-card preparation.
The machine is the Motorola MDR optical
mark reader.
If you were to put an MDR to work, you'd
get information into and out of your computer a whole lot faster. And much more
economically.
Because you wouldn't have the bottleneck and the cost of keypunching.
---' ..Or any other kind of keyboard
data conversion.
With the MDR, anyone who
can operate a pencil can prepare

computer-usable data as
a routine part of his job.
You could have "in_
stant" inventory control.
Super-speed order entry.
Self-updating quality assurance data. Fully automated payroll accounting.
It sounds blue-sky, of
course. But the logic of our approach becomes
quite clear when you consider that most of
the data you process by computer originates
a t the end of a pencil.
Which is precisely where our MDR collects
it.
With nothing lost in translation.

Faithful read ers of thi s column kn ow th at one of th e
flags we constan tl y wa ve is that of price-perform an ce
an alysis on a sys tem basis. While va lid on a system
b asis, the approach may be even more man datory on
som e sub-systems . W here a system comprises a CPU
and a number of remote term in als, the sub-system of
terminals and communi cation fa cilities can easily
have a cost equ al t o or greater t han th at of th e CPU .
It is thi s fact whi ch d emands a kn owledgea hI e, th orough analysis of the sub-sys tem alone, if design management is to b e responsibl e in doin g its job. ~ e
recentl y concluded a consultin g assi gnm ent wh erc!I1
th ese principl es were again confirmed . Th e system
was very typical in its function and purpose. Becaus e
of this, we feel that a review of the problem, the solu tion methodology, and th e res ults would b e of interest. As an actual case study, it is a report on a real
"what and why" of system design . Its significance is
that wh ere the company originally anticipated an annual expenditure of some $175,000, the resulting d esign will cost some $60,000 annually.
The XYZ company maintains 26 stocking warehouses throughout the U.S. , and a data processing
center in New York City. Customers' ord ers are received by mail and phon e at the warehouses. Th e con tent of th e customer ord er form is edited to match
XYZ's product cod es and quantity-makeups , and a bill
of lading is prepared. Th e goods are shipped and a
copy of th e B/ L is forw arded to New York wh ere
invoi ces are prepared and issu ed.
XYZ wanted to achieve : centralized control over inventory; more rea l-tim e correla tion b etween customer
credit information and th e shipping decision ; and a
speed-up of th e issu ance of invoi ces. This required
ord er processing at New York ra ther than in the warehous es. However, they did not want customers to mail
ord ers to New York b ecause it would brunt th eir "local distribution" image. Also, having th e warehouses
mail the orders in wou ld introdu ce unacceptable delays. H ence, a sub-system was required to:
• Input order data at the warehouses;
• Provide data communication between warehouses
and CPU;
• Print B/ Ls at the warehouses.
The first discussion of the problem was a brainstorming session, at which ideas were tossed out. The only
analysis or test at this point was whether the idea h ad
any correlation with the needs. As to terminals, they
90

inclu ded Te!etype Models 33 & 37, IBM 1050, IBM
2741 , Dura, MDS 1183, F acsimile, Novar 5-50, Digitroni cs Data-Verter, and Motorol a mark-sense reader.
In retrosp ect, th ere are oth er terminals we might
have includ ed. ( From this point on, "we" refers to the
consultants and XYZ's da.ta processing and customer
service staffs , as th e desig'n was a jOint and interactive
effort.) Na mes sll ch as Communi typ e, D atel, Compat,
Computer Transceiver, D ata Produ cts, C .E. , Viatron,
etc., came to min d. In defcl15e of not incl uding everyth in g, alI problems have to b e kept with in reasonabl e
bo unds. 1;1 the course of working on th e problem,
Univa c ann ou nced their DCT 500 and 1000, DASA
ann o un ce~l th eir D atakwik, and Teletype announced
their mag t ape terminal. AlI of these were then also
in cluded in th e poss ibi lity list. As to communica tion
facili ties, th ey includ ed WATS and POTS (Plain Ordin ary Telephone Service) . A cursory review of volU1n es imm ediately rul ed out private line service.
Th e nex t step was to defin e the d ata volumes and
tim es of transmission. Volumes were b ased on a
month-by-month stud y of the previou s year's activity.
The average orders per month were then doubl ed and
thi s figure was used as the design basis. It was felt
that we should design for som e growth , and doubling
was as good a target as any, allowing also for seasonal
p eaks over average. The input figures that were developed were 4000 characters per day per warehouse.
This, however, was based on complete entry of all
order data at the warehouses. Since the B/ L was to be
prepared and transmitted by New York, this
amounted to sending the same data from the warehouse to New York, and from New York back to the
warehouse. ' Ve decided th en to use a descriptive type
of entry at th e warehouse. In a kind of shorth and , we
would only enter minimum data to describe the order
content, e.g., a five character num eric descriptor of
"customers of record" rather than spelling out name
and address ; or three digit product codes rather than
spelling out produ ct nam es, etc. This approach redu ced the dail y volum e p er warehouse to 1600 characters. An important b y-produ ct was th e reduction in
form at complexity in the warehouse entry procedure.
The less data entered, and the less complex the format, th e lower the operator error rate per order.
Orders were generally received in the morning mail
so entry transmission could b e in the afternoon of normal shift. If so, the orders cou ld be processed at New
York in time to transmit El L's during the third shift.
Thus, the B/ L's would b e at the warehouse for picking the following morning: Finally, at this point in the
design, we calculated the weighted average transmission distance based on actu al average orders p er
warehouse:
Warehouse 1: 10 orders x 600 miles
Warehouse 2: 15 orders x 300 miles

ANALYSIS

At this point we had enough information to make
comparisons of various sub-systems and their costs.
This was don e generally for all of the originally conceived approaches, including those added during the
information gath er ing stage. Subscquently, two review sessions were held at which original ideas werc
weeded out as being obviously less desirable than others being consid ercd . Reasons may have been deterministic such as cost, or subjective such as insufficient
field service coverage, or insuffici ent delivery record
to show conclusive fi eld reliability. By the sccond review session, we had narrowed down to th e su b-sysitems as listed in Table 1.

Thc first sub-system considered was that of facsimile input and teletypewriter output. Facsimile was
tcsted because it would eliminate all keying operatio ns at the warehous e, th cse operations being cen trally perform ed , supervised, and controlled in New
York. Thus, the low error rates of centralized input
could b e obtained, and a very low skill level would b e
required at the warehouse. The transmission time for
the volume involved \ VATS lin es for least communication cost. Notwithstanding the use of VV ATS, and
even though total equipment costs were comparable
to other approach es, th e communication costs made
the facsimile approach too expensive for its b enefits.
Th e second approach considered was that of teletypewriter input and output. Such an approach was
included on intuitive grounds that the preval ency of
such an approach requires its consideration . Priced
first for Model 35 equipm ent, we th en recognized that
thc daily volum es were commensurate with th e capability of the light duty Mod el 33, and priced for this
model.
Th e third approach was that of input via a Motorola mark-sens e card reader, and output on a Teletype
MODERN DATAl April 1970

page printer. The reason for including the mark-sense
approach was that it also reduced the skill level reqUired at input. The incremental additional cost over
other possibilities was felt to be too great for the
benefits realized in this application.
A fourth approach was to consider the use of the
Teletype magnetic tapc terminal (MTT). As might be
expected this in creased equipmcnt costs and reduced
communications costs. This was too expensive by comparison and had questionable delivery and pricing.
Finally, \\'e considered the IBM 1050 to test for cost
of EDC on low speed transmission ; and the MDS
U S:3, to tes t for EDC on medium speed transmission.
0:otc in th e tabl e that the 1050's 14.8 cps speed brings
about cheap er communications than for Teletype, and
the ~[ o h aw k gear at 1200 bps is cven cheaper in communica tions. The Mohawk gear was not dramatically
effective in reducing communication costs, however,
because the average warehouse was transmitting
within three minutes even at teletypewriter speed.
Even if we in creased this speed, we still had to pay a
three minute minimum on the call. The primary impact of both th e Mohawk and the Teletype MTT was
on BI L transmissions. Here we had greater volume4000 characters per warehouse - and we were to transmit on third shift when the new one minute minimum
applies .
As far as EDC was concerned, then, if we were to
have it, it would be with the 1050. Management, however, wanted a justification for the necessity of the
EDC incremental cost. For this we conducted a test
as follows. Each day for a two-week period, a test
transmission was madc from two warehouses, each located in a section of the country historically poor for
data transmission. Each transmission, made several
tim es morning and afternoon, consisted of 1600 characters, the avcrage warehouse entry. The test results
were :
Order error rate
Bit error rate

0.362%
less than 1 in 106

\Vith th e use of parity for error detection , we felt we
wou ld achieve another order of magnitude improvement in undetected error rate. On this basis we concluded that automatic rctransmission was unjustified.
( Please don 't jump to conclusions or view this as a
gC'nera l truism. This was a value judgment for this
situation, for this system, based on this sct of .data.)
\Vith all reports in, the study indicated the subsystem should comprise Data Phone Teletypewriter,
with input during first shift, and unattended output
during third shift. In addition to low cost, other advantages accru ed. The Model 33 is very easy to operate, thus aIl eviating the conccrn over high skill level
operators in th e warehouses. Also, the Model 33 is still
available for Data Phone service from the operating
telephon e companies. This means 30-day termination
on equipm ent if system needs change, and a generally
high er probability of competent field. service.
Th e total study effort was on the order of 20 to 30
man-days, includin g XYZ p ersonn el. As such, we can't
present here all of the analyses we went through. Nevertheless, we hope this presentation gives a good map
of sub-system design criteria and procedures.

Time-sharing is like renting your very own busy signal.
If your service bureau keeps you
waiting , it's probably because
somebody else is getting served
fi rst.
But now there's a different kind
of time-sharing that only you
can use.
It's called the Interplex System I.
It's an in-house system w ith a 12K
general-purpose computer ,
hard-wired to as many as 16
specially designed terminals . So
you don 't need phone lines.
And because it's your own
in-house system , you can use it

as much as you want without paying an extra cent fo r it.
It's easy.
Our new time-sharing terminal is
the first to combine BASIC
language programm ing with an
electronic calculator in a single
desk-top unit. So you can do up
to 90% of your time-sharing jobs
in BASIC without leaving your
desk. And for a lot less than
you ' re paying now.
You won 't need any more equipment, because the terminal 's also
an elect ron ic calculator. So you
can even stop in the middle of
CIRCLL NO. 60 ON INQUIRY CARD

your own program to run your
calcu lations. And you don 't have
to wait for anybody else.
The Interplex System I. It's a
d ifferent kind of time-sharing .
You share it with yourself.

Too late to make the star-studded terminal show at
the '69 FJCC, Corning Glass Co .' s Corning Data Systems is now adding another ingredient to the already
rich graphics brew. Their new, as yet unannounced,
CDS 904 time-sharing graphic display terminal surfaced during an informal conversation with one of
their expanding sales force. Now, after comprehensive field trials , prices are available and deliverie s are being scheduled.
The CDS 904 has a number of usually hard -tocome -by features incorporated in its basic design
options and support, such as fast hard copy and a
slide overlay . It can be attached to any time-sh aring
computer via switchable voice grade telephone lines
at 110, 300 , and 1200 baud dat a rates in full or half
duplex modes . It can handle asynchronous ASCII
data and , at 110 baud, is compatible with Teletype
systems.
Although the concept is not new, the CDS 904
uses a rarely applied photochromic glass storage
tube ; in this case , a Corning proprietary development. Photochromic glass darkens when exposed
to ultra-violet light and becomes transparent again
when exposed to infrared light. The resulting display
has remarkably good contrast and is relatively immune to difficult ambient light conditions . The tube
image is projected onto an 8 % " x 11" screen fixed
at a near vertical position for user viewing and also
used to produce excellent hi gh contra st hard copy.
The slide overlay feature allows correlating fixed
stored data with newly computed results simply and

96

easily. Displaying stored data on top of already di splayed new information can create display management prob lems quickly if t he tube is to present both
displays simu ltaneously. A slide overlay gets around
th is nicely and has other neat applicati ons as well. It
can be used for menu displays and selection as well
as for forms and gri ds . When coupled with the hard
co py output , it becom es a ve rsat ile tool for producing business and engineering data on fi xed report
format s. Si xty-four 72 character lines are standard
for vertical page orientation. A 90 0 rotation mode
orients the page horizontally and results in formats
that are 94 characters wide. A double size character
mode is also available.
Using either 2 or 4 ASCII characters, the CDS
904 produces vectors up to 2 .73 inches long at
speeds of 7.5, 20 and 82 inches per second at 110,
300 , and 1200 baud, respectively . When 4 characters are used , the vectors may be visible or invisible.
Analog graphical input is either by a joystick or
mouse option. A tablet is in the works, and presumably will be available soon . A 58-key main keyboard
and control panel with a full set of ASCII characters ,
a 14 key data entry island with associated cursor,
hardcopy , overl ay, vector, character size , and erase
button s round out the 700 -pound terminal
configuration.
There is also software - a refreshin g departure .
Th e package cont ains 39 primary and advanced Fortran IV subroutines ; furnished wit hout charge to
users . Primary subroutines perform a group of basic
functions such as drawing vectors from current cursor positions to specified locations . Advanced sub routine s make use of the primaries to display data
with minimum user involvement. Routines accomplish windowing; plot data in Cartesian , semi-log,
log-log and polar coordinates; scale di spl ays; draw
curves , circles , and arcs ; and fit polynomials .
The $19K basic price range, which includes hard
copy and film overlay , puts the CDS 904 in the carriage trade class so far as non -refresher tube terminals go . But the 904 looks as if it has the Moxie to
belong there.

THE SYSTEMS SCENE

DATA BASE SYSTEMS

Th e Systems Scene is a regular monthly column written by
Je rome Wiener and Thomas DeMarco of Mandate Systems, Inc . '
Readers are inv ited to submi t comments a nd questions on new
developments in systems to: The Systems Scene, MODERN
DATA, 3 lockland Avenue, Framingham, Mass. 01701

How should a data base b e organized? The answer
proposed by the Conference on Data Systems Languages' (CODASYL) Data Base Task Group is "How
shouldn't a data base be organized?" Anything goes,
including ring structures, tree structures, multidimensional bidirectional chains, etc.
It's very nice to b e able to operate on a d ata base in
a conceptual manner as:
MOVE (SCHWARZ AND ASSOCIATES OF SCHWARZ)
or PURGE (MENSHEVIKS AND REVISIONISTS ).

TO SIBERIA

But it is distressing when such an operation involves
passing the whole data base sequentially. The unfortunate fact is that the way a data base must b e
organized is a function of the device on which it is
resident. (This was our guiding concept in laying out
the file structure of CALL/ 360 and we believe that
the system handles its files as efficiently as anything
now running. )
What the Data Base Task Group has proposed is
really a number of different ways a programmer can
pretend his data base is organized. At least two manufacturers are now building systems to simulate the
structure suggested in the CODASYL report. The
manufacturers, of course, have everything to gain.
It is interesting to note that most of the features
proposed in the report are variations of the same
thing: they give the programmer the power to treat
his data base as though it were resident in an associative memory. The most important result of the efforts
of Mr. Metaxides and the Task Group w ill probably
be in the area of hardware and system architecture.

Machines will be built to run efficiently with the data
base organization they have proposed.
To make a head-per-track disk into an associative
peripheral does not seem like an impossible problem.
Heads would always be in the read mode, transferring
data into shift registers. (One register per head .)
Shift registers would b e continually matched against
the contents of a character string specified by the
CPU as part of the fetch operation. Whenever a
match occurred, the rest of the record would be transmitted to the CPU. The head would then b e turned
off until the next fetch. Matches at other heads would
be ignored during transmission and picked up on subsequent revolutions. A full turn of the unit without
any further match would indicate end of transmission.
Such a device could make the running of a fully
organized data base much more efficient. It would virtually eliminate the task of routine re-organization.
Most headaches come, not in running a data base,
or programming for it, but in the data collection and
reduction. Forms design is a particular stumbling
block. (This is the data processing world's version of
the Pregnant Girlfriend Dilemma: soluti ons are eith er
bad or terrible.) When the forms are questionnaires to
be filled out by respondents, th e problem is even
worse. There is almost no possibility of passing the
work directly to keypunch without an editing phase.
Some special cases can b e h andled effectively with
sense mark forms or by making use of the increased
flexibility of OCR or key-to-tape. The more general
case, involving variable length and alpha data, ends
up being edited and mailed off to someplace like
Korea or Barbados or Newark for reduction.
Most data bases cost one cent per character or more
to build. The best deal is a data base that is a byproduct of some other operation. With the advent of
computer typesetting, some interesting things could
fall out nearly for free. If law books were set via computer, for instance, it might b e possible to put together a law research system using the text tapes to
build the data base. When dictionaries are set by
computer, translation data bases can be built cheaply.
Someday.

Information Management System /360 is a new common data base and data interface system b eing d eveloped by IBM. Data Language/l is the d ata interface
language used to access the data base without concern to the (ch anging) details of its structure.
IMS /360 is designed to become part of as under
multiprogramming with MFT-II or MVT. It also involves powerful teleprocessing as well as b atch capabilities, simultaneously. Besides DL/ l , IMS includes
modules
for
communications
control,
applications scheduling, and ch eckpoint and restart.
IMS allows considerable flexibility in the addition
of records to the data base to accommodate new applications without affectin g existing programs.
Therein lies one attraction. In addition, it is a Type I
system, fully supported by IBM for present and fu ture operating systems, and therein lies another attraction.

WHEN SHOULD YOU CENTRALIZE?

A centralized data base system of the type IMS offers
is valuable when a number of programs share much
of the same data. The degree of sharing d etermines
the economic feasibility or even necessity of going to
a common data base system. Of course, th e alternative is staying with the traditional independent programs and their files, and just re-entering th e fresh
data required for more than one fil e or, in some cases,
performing routine fil e conversions for subsystems.
When this traditional method results in hairy tangles of programs, files, and updates, you should look
into a common data base system like IMS.

HOW DOES IT WORK?

The IMS data base is set up in a h ierarchical fashion
in multiple levels, as shown in Fig. 1. Four-character
mnemonics or codes are established for each record
segment at each level. The application programs use
these mn emonics without regard for the location of
the records they reference - this is the concern of
IMS. Thus, new records may b e added for use b y
oth er programs without affecting existing programs.

Fig. 1 Com pa ny IMS data base reco rd segment level stru cture-engineerin g da ta added . ( From IBM IMS/ 360 App licatio n Descriptio n Manual
H 20·0524.1.)

A portion of the total data b ase that constitutes the
da ta file for a particular application program is established in a table. Each of these files is then accessed
b y means of these communication tables. The address
of the p ertinent communication table is given in order to access the required data. IMS locates a particular lower-level record by referencing the last record
of the next-higher-Ievel record preceding it (the "parent" record).
Any application program usin g DL/ l is essentially
a subroutine to IMS . These application programs may
b e written in Cobol, PL/ l , or Assembly language.
Some powerful report generators have also b een interfaced with DL/ l to reduce the amount of programmin g necessary to produce reports from the d a ta
base. One of th ese is Cullinane Corp.'s CULPRIT report generator.
When the application program gets control from
IMS, it also gets , as arguments, the addresses of the
Program Communication Blocks. These "PCBs" are
used as communication regions b etween the application program and the data files they access. There
is one PCB for each data fil e.
Thus, the first statements in the Cobol procedure
division of a typical application program are ENTER
LINKAGE, then ENTRY 'DLITCBL' USING
pcbname-l, . .. p cbname-n, then ENTER COBOL.
Later da ta fil e calls are accomplish ed by CALL
'CBLTDL' USING function-code , pcbname, segment
I/O area, ssa (segment search argument) . . . SpeMO DE RN DATAl Apri l 1970

cial provisions are made for other operations with records and fields in the procedure division, and for
definitions in the data divisi on.

STATUS OF I,MS

IMS has completed its preliminary "alpha" field test
for feasibility of design, and is in its final "beta" field
tests for actual operational implementation. It is rumored that something on the order of 50 companies
a re already implementing it, with 250 or more having
committed themselves or expressed serious interest.
The system appears to b e fairly well along. Most of
the problems appear to b e in devising new data base
and other design approaches to cut down access time
and overhead (maintenance) cost, the traditional
problems incurred by large data bases. However, the
system does work and should prove valuable to those
who are d etermined to go this direction, and want to
go it with IBM.

CONSIDERATIONS

As yet, we have no indication how IMS will be
priced ; but whatever its cost, it is bound to b e insignificant compared to the costs of implementation
and maintenance.
The costs of implementation start first in nailing
down inter-company, inter-subsidiary, inter-divisional,

and inter-departmental requirements. Inevitably, as
flexible as the IMS data structure is, some will feel
forced into a mold and want something difficult.
Second, the sheer task of defining in detail a large
data base requires considerable investment. And there
is no out here - every header, record, and fi eld must
be defin ed, reviewed, reworked , approved , fully documented, and distributed with directions for use.
Third, th e collecti on and entry of all the required
data is a task that can be appreciated by anyone wh o
has b een involved in the implementation of even a
relatively modest "mono-application" program.
Finally, there is the large cost of maintaining the
data base once it is established. This has killed many
large common data base systems.
To achieve a ny degree of success with such a system, the p eople in charge would b e w ell advised to
b~ sure tha t every datum entered is a da tum needed .
Until the industry comes up with a me thod of economically maintaining marginal data along with the
hot stuH, users should proceed cautiously and use all
the experienced personnel they can get to advise
them in this phase of the project. The design of the
data base is a very crucial factor and cannot b e overemphasized. It is an art in itself.
IMS is an interesting and advanced system, and implements an important step in the mu ch-n eeded d ata
interface concept. It should greatly assist those committed to implementing a common data base who
might have had to go a much more hazardous and
less generalized and supported route.

On weekends, when the switchboard operators
are not on duty at a mid-Western finance company,
the incoming telephone calls ring the telephone at
the Mod 30 in the computer room. There is also a
telephone at the Mod 50 which is about 25 feet
away, but it has a different telephone number. The
computer operator (a recent arrival to the United
States) was new on the job. The telephone rang at
the Mod 30 and the computer operator answered,
"Mod 30 . . . Jose speaking." The voice on the

Moore New Ideas for
Data Processing
Quick fix on back orders

When inventoried parts and/or raw materials
run out, production schedules get out of whack.
Moore has a special follow-up system that permits
purchasing departments to provide more reliable
data for production planning. System is automated
for speed and accuracy. Eliminates tedious tracer
systems and mistakes inherent in manual systems.
Ask about Idea #331.

Speed cash flow with
faster billing

The bottleneck in billing often occurs after
bills have been prepared. Moore can show you how to
eliminate the wasteful stuffing, addressing, and
preparation steps that bog down otherwise good
systems. System even provides customer with a
postage-paid reply envelope to encourage prompt
payment. Envelope also correctly identifies
accounts. Ask about Idea #332.

Employee relations get
assist from computer

When company ID cards are issued to cover
company-sponsored special events, preparation can
be costly and time consuming. Moore has an idea
for breaking this bottleneck which gives employees
a complete listing of scheduled events by date
and location. Ask about Idea #333.

Want to double
printer production?

One way is to set up for printing two-wide.
But don't stop there. Get a Moore 315 Interstacker
which separates the forms and interleaves them in
strict numerical order • • • trimmed and ready
for further steps. All at speeds up to 300 feet
per minute. Ask your Moore man for information
on how the Moore Interstacker can process your
two-wide forms at rapid speed.

When was the last time
you asked Moore for
a new idea?

If you haven't, you should. Moore men have
been trained to apply old ideas to new problems,
or create new ways to solve old problems. And there
are more than 2600 of these Moore men constantly
applying and exchanging ideas. One Moore idea
may be what you need.

SAFEGUARD-A Forum of Opinion

The January issue of MODERN DATA contained an editorial on llie Safeguard-ABM controversy which invited Our readers to reply to the question: Is the
ABM 'System capable of being practically implemented, or is it b6yond our current state-of-the-art?
The editorial stressed that while a considerable
amount of literature has been generated concerning
the moral and political aspects of the Safeguard-ABM
system, comparativel)' little h as been addressed to
the technical issues raised in connection with Safeguard's computer system by "individuals with actual
computer experience."
Included with the editorial as the first contributions
to this "forum of opinion" w ere l etters solicited from
two such experienced individuals with opposing points
of view. The first letter, fr0111 Dr. John S. Foster, Jr.,
Director of the Dept. of Defense, Office of Defense
Research and Engineering, answered a MODERN DATA
request for a reply to "the number of questions raised
in connection with the Safeguarcl-ABM computer

To the Editor:
I n response to your call for opinions on the ABM issue, I
would like to add a few specifics to the general statement
of Computer Professionals Against ABM, of which I am a
signer.
I am not familiar with Mr. Foster's background , but I
have to assume from his letter that he has little or no
computer experience. His poor analogies are clearly refuted
by the CPAABM statement, and if he had any experience
with large systems he would know that input simulation is
an acknowledged inadequate technique for testing pro·
grams . First of all, we know we ca n not prove that a large
system works . The most that can be said for any program
is that it has worked for a great variety of inputs for a lon g
time; and simulated inputs are not sufficient. Their completeness is the same function of programmer's understanding the requirements, as was the original program ming job . Therefore , there is a strong tendency to design
tests the system will be able to pass. If the program has
ignored a particular attack strategy completely, it is not
likely that the test inputs will include that strategy. Worse
yet, if the programmers have failed to imagine the possibility of some accident, they are hardly likely to test for it,
except by accident .
Then there is the matter of "point of diminishing returns." At some point in the de -bugging process of a very
large, complex program , it becomes reasonable to assume
that even known errors should not be corrected due to the

system." The second letter was fOlwarded to MODERN
DATA by Daniel D. McCracken, a well-known software authority and chairman of "Computer 'Professionals Against ABM." The editorial concluded "in
the hope that those of our readers who are qualified
to shed some additional light on this important issue
will do so by sending us their comments."
\Ve are pleased that many of our readers found the
t ime to respond to this request, and the following letters are some of the replies we have received so far.
In subsequent issues of MODERN DATA
shall continue this "experiment to help us determine not only
whetller we can accept Safeguard as a viable program, but whether you, the professional, care enough

we

to think about ;t."

high probability that worse faults will be introduced by the
change. Virtually every operating system, compiler, and assembler has such known bugs. The Electronic Switching
System of Bell Laboratories is just such a program. I
worked on that system for ten years, and can attest to the
fact that it has been in use since 1965 with known bugs,
some of which have been changed by a slow evolutionary
process involving real world data and a feedback mechanism that will not be possible with the ABM system . The
telephone system 's large program is judged "good
enough," and is never expected to be perfect. But "good
enough" is not good enough for a system that can unleash
nuclear weapons.
Also , there is the matter of changes. Assume, optimisti cally, that we manage to develop a harmless system .
Clearly the program will require continual revision to keep
up with improved offensive techniques. We can be quite
confident that at some sta ge of its continued metamorphosis, our poorly tested, but apparently harmless system,
will become frighteningly dangerous.
If the military industrial complex feels the need to build
an ABM system, it won't be stopped by letters to MODERN
DATA, but I couldn't let Mr. Foster's statement go
unanswered.

To the Editor:
This letter is prompted by your editorial in the January issue
of MODERN DATA concerning the ABM Safeguard system .
As a computer professional I believe that this system will
perform in a satisfactory manner including the hardware
and software subsystems.
The letter from Mr. McCracken and the Computer Professionals Against ABM shows a lack of confidence in the abil ity of engineers to design a reliable complex system . This
ABM system will be developed by engineers that routinely
must succeed in difficult tasks; tasks that many times are
not even well defined when final commitment must be made
on them . For instance the large and very successful Apollo
moon program is a good example of the accomplishments
of engineers .
The software engineering problems that will be encountered in the ABM system are indeed staggering but I have
every confidence that these engineering problems will be
satisfactorily overcome and the computer subsystem will
110

perform up to standards. The large amount of software
engineering development that will be accumulated during
this effort will be an important byproduct.
Also as a professional nuclear engineer, I do not feel the
apprehension over the testing or destruction procedures
that the CPAABM present in their letter. The simulation testing of the ABM system is again an engineering problem
and can be handled without the use of nuclear warheads,
On the other hand, high -altitude nuclear explosions have occurred before and the accidental occurrence of another
would not be desirable but neither would it be catastrophic .
In summary, the ABM system developed by superior engineering talent will be a successful operating system.

To the Editor:
I would like to take advantage of your invitation to com·
ment and hopefully shed a small additional ray of light on
the ABM issue. I n my op ini on, the hope of success of the
system is high enough to justify our attempting it. Admit·
tedly , the system is not without risk , but what new system
ever has been? In the foll owi ng paragraphs, I would like to
present some of my reasoning in arriving at my position .
I do not feel parti cularly qualified to analyze the require·
ment or the threat, yet some weight must be placed on the
consequences of deciding to continue or to cancel an ABM
program . The effectiveness of any ABM system lies some·
where between useless if it does not work at all , to strate·
gically decisive if it is completely effective. In the latter
case, the possessor of such a system co uld use his offen ·
sive weapons with impunity in the full realization that he is
immune to retaliation. Clearly , the system we are consid ·
ering here lies somewhere between these two extremes (if I
am right that it will work after a fashion) . To continue a
situation of no defense at all without so much as tryin g t o
improve our position is to insure that we shall never have a
ballistic missile defense. This is an intolerable situation.
I would like to avoid the vitriolic rebuttals wh ich are occa ·
sionally seen in technical journals, but it seems desirable to
examine in further detail the arguments presented by Com·
puter Professionals Against ABM in the January 1970 issue
of "MODERN DATA." The air traffic control system analogy
is a good one, but it does not seem to take into consid·
eration some of the things that can be done to avoid the
pitfalls described . Undoubtedly, a great deal of effort must
go into the development of simulators. In the initial stages,
complete simulation would be required . As the system is
developed , only inputs t o detection sites would be simu·
lated. The outputs of these sites would then be compared
aga inst results which are expected for actual ICBM detec·
tions under the circumstances which are simulated. Once a
series of simulat ions has been developed and validated by
a te chni que such as that described above, the next step is
to introduce these results into the ABM control system and
analyze the output against that expected. Finally, when the
response from the ABM control system has been validated ,
simulated firings should be made, and finally live firin gs
(with dummy warheads) should demonstrate that the sys·
tem performs properly. This simulatio n, if carefully planned
and executed , should eliminate the lion ' s share of the risk.
The election·result·predicting computer does not seem to
be a particularly cogent analogy. The program errors men·
tioned in the previous letter could certainly have been de·
tected by relatively simple simulation , hence I conclude
such testing must not have been done .
Evolutionary development has certainly been shown to be
the proper approach to system growth, but a system must
start somewhere and evolve from that point. ABM can
hardly start as less than a few closely related sites, which,
if successful , would grow into a nationwide ballistic missile
defense.
The hardware reliability problem which was mentioned is
easily reduced , although not eliminated, by use of redun ·
dancy and automatic switchover - a luxury frequently not
available to data processin g systems . Certainly the election ·
predicting processor did not have these features , presum·
ably for economic reasons . I have personal knowledge of
several large processing systems where down time averages
a few minutes or less per month, and techniques exist
which, I believe, could reduce recovery time to the millise·
cond range.
Turning now to the four specifics of the earlier letter, it is
true that the computing task is extremely complex. On the
other hand, the mathematics of ballistic flight , either pow·
ered or not, are well known, and the equations lend them·
selves to explicit solution.
There are only a limited number of countermeasures
which an attacker might use . The number may be large, but
it is finite. Furthermore, many of his options may be " don ' t
cares" so far as we are concerned. For example, if he sabo·
tages a radar site or merely jams all its available fre ·
quencies , from our pOint of view it is a single alternative. In
any event, his alternative ca n be listed and our courses of
action matched to them.
Testing is possible, but admittedly not with live war·
heads. However, the problem is to put the ABM in a specific
volume of space at a predetermined time. This can be
tested . Firing mechanisms, safety mechanisms, destruct·
mechanisms, etc. can all be checked out by actual test .
Only the kill radius cannot be actively tested, and I feel
certain adequate data to determine this parameter is al·
ready available .
Evolutionary development, as mentioned above, would
occur on the basis of test data, both live and simulated. It
would begin with the early simulat ions and continue
through deployment of the first ABM until the ultimate ABM
MODERN DATA/April 1970

system is deployed nationwide. Harking back to the elec·
t io n·predicting computer, surely its evolutionary devel·
opment does not occur in quanta every four years. In all
likelihood , bugs are eliminated and improvements imple·
mented continuously during the whole period between elec·
tions. In like manner, the ABM control system will not need
to wait on firings ·i n·a nge r.
Tactical warning may be short indeed. However, the deci ·
sion to fire need not be left to the processor if we keep
ABM reaction time short and thus preserve those precious
minutes for hu ma n decision. Certainly, priority should be
high enough that the slightest indication of attack is relayed
directly to the President and the Chairman of the Joint
Chiefs of Staff for immediate evaluation. However, it must
tie rea lized that installation of the Safeguard syste m will not
dec reas e warning time and, today, in those few minutes of
tactical warning, a decision must be made to release or to
hold the retaliatory force. A bad decision concerning the
defensive system if installed would not have as far·reaching
effects as a wrong decision to launch the retaliatory force .
As a practical matter, there are many intelligence in·
dicators which would gi ve far greater warning than a few
min utes or even hours . With the occurrence of some of
these indicators , the system (including the people who
make decisions) could move to more and more ready condi·
tions such that good decisions can be made in a short time.
Furtherm o re, the system can be designed such that it could
not, under any circumstances, cause a launch unless hu·
man intervention has entered a "guns free " command.
What damage can be caused by an inadvertent or er·
roneous launch? It is true that the ABM will have a nuclear
warhead, however, safety devices would normally be pro·
vided to prevent the warhead from arming below a pre·
determined alt itude , or to disarm it should it descend again.
A destruct mechanism controlled from the grou nd would
cause the missile to be destroyed in a non·nuclear detona·
tion whi ch would also cause disarming of the nuclear head
to prevent detonation upon impact. Thus , the only danger
in an erroneous launch would be that of a low·order, non·
nuclear detonation upon impact of the ABM . Such an event
would be deplorable, of course, but, even in the unlikely
event that it should occur in a metropolitan area, it would not
be a national calamity.
The probability of an ABM launched in error, assuming
by chance a trajectory which would appear hostile to an ·
other nation, is quite remote. In addition, as soon as it is
discovered that we are not under attack and that our ABMs
have been launched , we would immediate ly take steps to
destroy them and to advise any potential hostile nation .
Their detection systems will already have detected the
launch , the trajectories , and finally the destruct.
From a technical point of view, the intercept problem is
not a new one. It has been solved for both manned aircraft
and for missile intercepts. There may be a number of differ·
ent conditions under which intercepts may have to be made
and the program will have to be able to recognize which set
of conditions exi sts at any particular time . This, too , repre·
sents nothing that has not been done before. There may be
conditions under which intercept must be made which have
not been defined as yet, but these conditions exist only in
finite numbers and can be defined.
There are many analogies to the proposed Safeguard pro·
cessi ng system . All of the achievements of the space pro·
gram can be cited. Specifically, the Mariner projects are
worthy of mention as are all the manned space flights cui ·
minating in Apollo and successful landing upon the moon .
There was little evolutionary development in those pro·
grams. In each case, there had been simulation, but each
launching was a one·of·a·kind. Each had to work the first
time and , strangely enough, all of them did.
The moon landings had been simulated on earth, but
there was far less realism there, it seems to me, than is
possible in the Safeguard program. In the case of the two
landings, a number of complex and untested things had to
work properly the first time . Certainly, the success enjoyed
by that program shows the sort of reliability and accuracy
that can be achieved with a very minimum of trial and error
type testi ng .
In conclu sion, for reasons stated above, I consider the
Safeguard ABM system to be technically feasible. In addi·
tion, the dangers of the system appear to have been greatly
overstated while little has been said to support the fact that
a workable ABM system confers a tremendous advantage
upon the nation which first develops it, even though it not
be perfect. In the absence of some better system, I urge
that we proceed with the Safeguard ABM system .

To supplement the 33 technical sessions (4 more than were given at Las Vegas last
fall), the SJCC program committee has scheduled several unusual special activities:
A Pre-university Technical Program
developed by none other than the
R.E.S.I.S.T.O.R.S. of Hopewell, N.J.
You'll have the opportunity to meet
this interesting and percocious group
of youngsters on Tuesday evening.

A Venture Capital Panel on Wednesday evening will discuss venture
capita l as it applies to companies in
the computer industry.

EXHIBITS
Although Atlantic City will host slightly fewer exhibitors
than were at last year's FJCC, AFIPS expects more than a
60% increase in exhibitors over the 174 companies that were
represented at lost spring's Boston conference. The exhibit
areas in Convention Hall will open Tuesday through Thursday at 10:00 A.M. and remain open until 6:00, 9:00 and
5:00 P.M., respectively.

~

CIRCLE NO. 69 ON INQUIRY CARD

Two Computer Science Theatres off
the main exhibit floor will operate
concurrently Tuesday afternoon and
all day Wednesday and Thursday.

A WORD OF ADVICE
The Atlantic City Convention Bureau claims that there are
"32,000 rooms in hundreds of hotels and motels within a
short distance of each other and the Convention Hall." Maybe so. But only if you count those for which bed-board and
"room" is interpreted loosely. Don't plan on finding
satisfactory accommodations after you arrive. Get your
reservations in now!

THE CHALLENGE OF UNBUNDLING
A summary of the dangers and opportunities which face both the computer user
and the IBM competitor as a result of the unbundling announcement.
new unbundled world of computers has forced
maturity on some computer users and spurred
them to a position of greater independ ence from the
computer vendors. As a result, many will achieve a
level of more effective use of their computer information system. For other users, unbundling could prove
bankrupting or otherwise disastrous.
For all users it means higher prices for their computer and all its support services. IBM lowered its
hardware costs by three percent, but now charges additional fees for education and training, certain field
engineering (including some hardware and software
maintenance services), systems engineering services,
customer software and consulting support, some basic
software (such as language compilers), and applications programming products .
For users who depend on the computer vendor for
everything - the "Linus blanket syndrome" - the
price increases may run as high as 50%. At the other
extreme will be those users who can get or train their
own staff to do everything in-house. Their price increase can b e as low as 5%. For the average user, the
price increases can b e held down to the 10% to 20%
range by careful planning and intelligent selection of
options. These options include buying the repriced
services from the vendor, "doing it yourself," or engaging any of a variety of outside firms or consultants.

T

These can include computer education companies,
software houses, maintenance firms, or even "lone
wolves." Since it is a very complex process to choose a
viable alternative with effective cost-performance, the
services of an expert consultant, in-house or outside,
may be required.
To help find answers to the question "What is the
true price of IBM's unbundling?", the full price increase can be calculated for any user company by
detailed attention to the various computer unbundling problem areas. Sbme of these price increases and
their effects on user costs are illustrated in Table 1.

HE

PRELUDE TO UNBUNDLIf\IG

Our earliest machines, built in government labs and
agencies, had no software at all. Programming was
done in absolute machine language. Gradually, assembly languages and compilers were developed.
IBM provided the Fortran language with its 704 computer by the mid-fifties. In 1957, Control D ata introduced the 1604 computer without software at a
drastically reduced price. Without software, their
market was limited to the most sophisticated scientific
users - there simply were not enough programmers to
go around. (Sound familiar?) So they were forced to

MODERN DATA/ April 1970

develop and give away a Fortran capability. The
computer industry was just not ready for unbundling!
A more recent entry into unbundling was made by
Scientific Data Systems (now Xerox Data Systems) in
1966, with separate pricing for their Cobol compiler.
They had sold 17 compilers by the spring of 1969.
Some software packages have b een developed and
sold with a high degree of success. The AutoHow
package, developed in 1964, has sold a number of
packages in four figures and has just penetrated about
2% of its potential market. Over 100 Mark IV packages h ave been sold a t a price around $30,000 each. A
communications software package for the IBM 1130
succeeded financially because IBM had no intention
of fillin g this limited market themselves. The SCERT
evaluation and simulation package has succeeded, as
has the COMPUMETER package.
But many more attempts to sell software have met
with less than success, if not actual disaster. A west
coast firm built a "b etter" compiler for an IBM 7040
in 1964, but the user could get the working (even if
un-'better") compiler free from IBM. The user was
unwilling to pay a cash outlay for potential or real
cost savings in improved running performance. The
market was not yet ready for unbundling!
In 1966, a well-heeled major computer network
company unsuccessfully tried a software 'buy, cleaning, and sell" operation. In 1968, a software house
built a "better" SORT package for an IBM 360, compatible with IBM's current SORT program. Then
IBM announced a new SORT program, with which
the competitor's package was not compatible without
major surgery. The company lost on the gamble and
was forced into a merger situation.
The computer world was not ready for unbundling

in the sixties! Will it b e ready in 1970? Will it be
forced to adjust to the realities of unbundling? I think
so . The compu ter users will have to mature. They will
also have to spend more. IBM has cut the umbilical
cord; the user must b ecome more indep endent of his
vendor somehow. The us er's "Linus blanket" has been
taken away. He is shaken and confused. H e has to
face up to the realities of the new, unbundled computer world and its increased costs. He must learn
how to reduce his price increases through careful
planning, training, and careful selection of alternatives for outside services.

EFFICIENCY THROUGH EDUCATION

At a recent seminar on the status, prices, and effects
of computer unbundling, Mr. Don Lees of Computing
Effi ciency, Inc. related that most users are shocked to
learn that they only get about 40% utilization of their
computer hardware. One signifi cant way t o reduce
computer costs and avoid unbundling price increases
(even for small users) is to train user operators, programmers, systems people, and managers how to
make effective use of multi-programming and other
advanced computer techniques.

Fred Withington of Arthur D. Little, Dan Bowers
of BCD Computing and of MODERN DATA, and Dr.
Daniel T eichroew of the University of Michigan
pOinted out tha t unbundling focuses greater urgency
on the problem of educating advanced "generalists"
for the computer industry - whether we call them
systems designers, systems architects, or information
analysts. This need presents an opporhmity for all
users, even small ones, to cooperate in a joint effor t to
train their own staff to replace vendor SEs. Plans for
an intensive advanced training program have been
formulated by the New York City Chapter of the Association for Computing Machinery. All user companies, large and small, have b een invited to participate in this pilot program to train advanced systems
design ers and information analysts.
There has b een a recent move to design four-year
and master's degree (MBA) programs to guide business colleges in educating the well-rounded information systems designer of the future. The National Science Foundation provided the Association for
Computing Machinery with a grant to investigate this
need and design such a curriculum. This committee,
the ACM Curriculum Committee on Computer Education for Management, is chaired by Professor D aniel T eichroew of the University of Michigan_
In addition to the college curricula, the ACM committee has recommended that a six-month intensive
course to train information systems designers be developed and offered initially through a pilot school.
The first pilot school is planned for the New York
area, to b e organized and assisted by volunteers from
the N.Y.C. chapter of the ACM. Students for this advanced trainin g will b e selected from p ersonnel with
college degrees who are currently working as systems
analysts, software specialists, EDP managers, computer systems managers, programming managers, operations managers, systems d esigners, etc.
The Association for Computing Machinery developed an d published a bachelor's and master's degree
curriculum for Computer Sciences as early as 1964.
Most universities are using a 1968 revision of that curriculum as a model, although they generally fall short
of offering the full curriculum b ecause of a shortage
of qualified instru ctors and over-specialization on the
part of the instructors they do have. The curriculum
is very good for the scientific side of the computer
world, but not for the business or commercial side.
Als o, as early as 1964, an MBA degree program in
computer methodology w as begun at the Bernard Baru ch School of Business and Public Administration,
CCNY. The instructors, in the early days, were mostly
part-tim ers from the business world. Recently, a midwestern business college contracted with Oyer Professional Computer Services, Inc. to design and to teach
a curriculum in Managem ent Information Systems at
three of its campuses. This appears to be the first
tim e tha t a college has contracted with a "for profit"
organization to design its curriculum or to teach.

THE EFFECTS ON IBM

IBM itself is somewhat confused over unbundling.
Systems engineers are sitting on their hands in IBM
branch offices with nothing to do b ecause users are
not ready, or budgeted, to pay for their expensive
services (free b efore January 1, 1970). Some systems
engineers are b ecoming salesmen, some are leaving,
some are transferring, a few are enjoying the vacation
and boredom .
IBM does not permit idle hands or h eads to remain
idle very long (a good business practice). In the next
few months we may witness a drastic shakedown period which will restructure IBM's profit centers into
5 major areas:
•
•
•
•
.•

Edu cation and Training;
Software and Consulting;
Maintenance;
Leasing, Marketing, and Sales;
Manufacturing.

These profit centers may subsequently b e formed into
separate divisions. Finally, as competitors, users, and
the Ju stice D ept. apply pressure, IBM may eventually
turn them into separate subsidiaries, with IBM itself
becoming littl e more than a holding company. In any
event, however, IBM will be the leader in the computer industry for a long time; they will always remain as a tough , seasoned, imaginative competitor.

..• .. .... . ... ............. .... "Through Greater Knowledge"

ized. They "do their things" with a thorough systems
approach and with sophisticated, dynamic planning.
They have tens of thousands of salesmen pounding on
doors, holding customer's hands, and trying to keep
them satisfied.
Many IBM competitors have already "bit the dust."
As a result of unbundling, many new competitors will
spring up only to meet the same fate. But some, those
with good, qualified people, will survive and prosper.
They will need to treat their own people and their
customers well. They will need to apply a thorough
systems approach both to their business and to their
customers' problems. They will need a sizable staff of
salesmen, well-trained in EDP, in their products and
services, and in sales techniques. (Every successful
non-manufacturing competitor of IBM will need at
leas t one salesman for every 2 to 10 other employees,
d epending on their products or services!)
Thus, those firms who wish to compete successfully
with IBM in any sector of the computer world must
provide: attention to their own people; systems support; high quality products and/ or services; knowledge of their market; good sales and marketing staff
and plans ; knowledge of their competition; the systems approach to their entire business; constant training of th eir staff; hard work and long hours (IBM
does this) ; clever strategies; and honest tactical
maneuvers.
Many firms and consultants will successfully compete with IBM. Many more will try and fail. It should
be a lot of fun for all.

the secand at·ticle, examine the cast and characteristics of te1'1ninal devices in the third, and C1'itically

will present same cast/ peljarmance trade-aff techniques and same dallars and sense results.

DATA COMMUNICATIONS-AN OVERVIEW

Data communications is herein used to d escribe that
part of an overall system which permits one or more
users to access a remotely-located computer. (The
concepts discussed can b e applied to data communications b etween two termin al devices - a processor
'not b eing in the system.) The airline reservation system is a well-known example of a system employing
communications. Fig. 1 illustrates the system treated
as three major subsystems. The subsystems are the
processor subsystem, the communications network,
and the terminal subsystem.
The function of the system is to respond within seconds to inquiries of customers in various locations
throughout the country. In a typical operation, a customer may ask a ticket agent whether a seat is available on a specified flight. The agent translates this
English language request into a format which is acceptable to his terminal device. The terminal device
changes the agent's input into a forrpat which is suitable for translation over the communications network.
The request reaches the processor via the commu134

nications network and terminal device. The agent
translates the received reply into English and replies
to the customer.
To bring some of the thoughts into focus, consider
the following situation. Suppose that a company has
two plants located 200 miles apart. Each plant has a
data processing center. Further, there is a 300 character per second data communica tions link between the
plants. Assume that due to equipment malfunction it
is necessary to transfer a 20-million character reel of
magnetic tape from one plant to the other in order to
complete a payroll run. The question is - should the
tape be b"ansmitted over the data communications
network or should it be taken by automobile to the
plant? Assuming ideal conditions and 100 p ercent
efficient use of the communications channel, 20 million characters, would require approximately 18Jf
hours to transmit at 300 chars./sec. Assuming that
one could achieve an average traveling rate of 40
miles per hour between plants, it would only take 5
hours to deliver the tape by car. Using 10 cents per
mile for the car and the station-to-station rate for the
data communications channels, using the car would
cost $20, the data link $222. Under these conditions,
using the automobile would be about 4 times faster
and would cost about Ylo that of the data link. A general point b eing made here is that normally data communications channels are suitable for sending relatively-low volumes of data per day. A second general
idea being suggested is that data communications can
be, and usually is, exp ensive relative to other system
cost; therefore, optimize the use of available communications services. The latter consideration .is treated
in more detail in the next article describing cost and
capabilities of available communications facilities.
It may be helpful in gaining some insight into what
goes on in data communications to return to the airline reservation system and follow a request through
the system. Fig. 2 illustrates the essential components
of a single data communications link to the processor.
The link consists of a customer, an airline ticket
agent, terminal device, a modem, communications
channel, a second modem, and the processor subsystem. In operation, the customer communicates a
request to the agent using the English language. The
agent, using a combination of typing into a keyboard
MODERN DATA/April 1970

and a special precoded card, translates the customer's
request into a form that the terminal device can accept. The terminal device translates the agent's input
into digital signals. Digital signals are not suitable for
transmission in the communications network except at
very low speeds because of the communications network bandwidth. Therefore, a modem is interposed
between the terminal device and the communications
channel. T he modem, a contraction for modulatordemodulator, converts the digital signal into a modulated signal. In reverse direction, the modem converts
analog signals from the line into digital signals for the
terminal device. The number of characters per second
that can be transmitted over a given communications
channel is highly-dependent upon the signals generated by the modem. For example, on a voice grade
line which has a bandwidth of approximately 3 kilohertz, transmission rates varying between 150 and
900 characters per second may be achieved depending upon the way in which the modem translates the
digital signal and the signal detection method used.
Generally, although not necessarily, a trade-off is
made between higher transmission speed and increased error rate when the same communication
channel is used. The error rates can have a significant
effect on the cost perfo rmance achievable with a
given communications network. At a telephone
switchin g cen ter, a frequency conversion generally
takes place when long distance transmission is involved. At the processor, a second modem converts
the modulated analog signal into a digital signal acceptable to the processor. For those interested in examining the operation of the terminals and lines in
greater detail, Reference 1 is recommended.
Characters per second, bits per second, and baud
rate are frequen tly used to express the rate a t which
data can be transmitted. From the users' viewpoint,
characters per second are the most meaningful measure of data transmission rate. For a given character
transmission rate, the bit rate can vary. For example,
10 characters per second can be 75 or 110 bits per
second depending upon the code and type of transmission to be used. Baud is an old telegraph term
signifying the maximum modulation rate of a code. It
is recommended that this term be dropped as it has
little value in modern data transmission.
MODERN DATAl April 1970

The cost of data communications is generally high
relative to the cost of other system elements. It is,
therefo,re. generally well worth the time and effort to
perform careful cost/performance tradeoff studies in
the design of the data communications portion of the
system. Some of the cost/ performance trade-off considerations. will be examined in the last of this series
of articles. The estimated cost for the system to be
considered are presented here to indicate the relative

The communications network is the most expensive
of the subsystems. Data communications hardware requires $59,000 per month of the total $136,000 per
month, or 43% of the total cost.

DATA COMMUNICATIONS CONCEPTS

One of the basic requirements in data communications is to provide a data connection between two
points. There are three basic connections - Simplex,
Half Duplex, and Full Duplex.
A Simplex connection can b e made to permit transmission in one direction only. If the connection is
made to permit data to be sent from a remote terminal to a processor, that is the only way data can be
transmitted. Simplex connections are not commonly
used in data communications.
A Half Duplex connection permits transmitting
data in either direction. However, transmission can be
in only one direction at a time.
A Full Duplex connection permits simultaneous
transmission in both directions. The common tele..phone uses a full duplex connection. As a rule of
thumb, full duplex is approximately 10% more expensive than half duplex.
Having connected two points, the next question is
how to transmit data most economically from more
than one device in a geographical area to one or more
devices in another area. As an illustration, assume
that in a system, five 10 character per second terminal
devices in Chkago are to send and receive data from
a processor in Philadelphia. One connection method
is to use the dialed network in a manner similar to
using a telephone. Fig. 3 illustrates such a system. In
operation, a user dials the telephone number of the
modem (also called a data set) at the computer. After
the connection is made, data transmission may proceed. The cost is the same as that for telephone ser140

vice. Time-sharing services use the dialed network for
data communications.
Assuming that the traffic between the five terminal
devices and the processor is sufficiently low that a
single 10 character per second data transmission channel can service all five devices, then a polled line,
illustrated in Fig. 4, may be used. In operation, a user
enters his message into the terminal device and depresses a send key. The message is stored in a local
buffer at the terminal device. Typically, this buffer
may b e punched paper tape, a magnetic drum, or a
small core memory. The processor contains a program
which "polls" each device in a pre-specified order.
The "poll" is an inquiry as to whether that terminal
device has a message ready. If a message is ready, the
device is connected to the line by the processor and
transmission initiated. If the device did not have a
message, the processor may connect the device to the
line and send a message to the device Or may poll the
next device. When a half duplex polled line is used,
only one message may b e transmitted at any instant.
The m essage may b e either from the terminal device
to the processor or from the processor to the terminal
device. When a full duplex polled line is used, one
message may be sent in each direction at the same
time. The message may be from and to the same or
different terminal devices.
Fig. 5 illustrates the system when the traffic is
sufficiently heavy or when other considerations require that each terminal device be connected through
its own 10 character p er second line.
Fig. 6 illustrates another way of.connecting five devices to a processor, each having the equivalent of a
10 character per second connection to the processor.
The multiplexer, also called a concentrator, accepts
data from a number of low speed lines and transmits
the data over a single higher speed line.
The approximate monthly line costs for the three
dedicated systems is tabulated below.
Rental approximately $690/month
(To this at least the dollar value of processor time to
accomplish polling should be added.)
POLLED LINE:

FIVE DEDICATED

10

CHAR/SEC LINES:

$3450/month

$890/month
(To this at least the rental of multiplexer should be
added.)

ONE VOICE GRADE LINE:

Comparing the five dedicated lines to the multiplexer dedicated line configuration about $2560 per
month for the multiplexer is the breakeven between
the two configurations. In many applications, the use
of multiplexers can save substantial line costs.

THE GREAT SHORTAGE

e are constantly reminded of the urgent need for
more programmers. Numerous articles have been
W
written about how to interview and evaluate a programmer; large amounts are spent ta, keep programmers happy within their company environment; and
we witness daily the battle to attract programmers in
the classified advertisements. If the present looks
pretty bleak, what can we expect for the future?
Let us look at some statements and statistics related
to electronic data processing:
• In 1968, there were approximately 70,000 computer
installations. This figure is expected to increase to
210,000 by 1975, and to 350,000 by 1980.
• The ratio of programmings costs to equipment
costs is expected to change from the 50/50 mix of
1968 to 60/40 in 1970, and to 80/20 by 1975.
We can draw some very interesting conclusions on
the number of people that will be required to keep
the computers of 1975 humming. Suppose 200,000
persons were employed full time in programming support at the beginning of 1969 with a real need for at
least another 50,000. With more than three times as
many computers in use and four times more software
support required per computer, the theoretical need
for programmers in 1975 would be 3 x 4 x 250,000 =
3,000,000. It took more than ten years to train the first
200,000 programmers. New programmers leave
schools in greater numbers now, but the demand still
far outpaces the supply.
With the quantitative demand on the increase, the
demand for more qualified people will similarly increase. Programmer qualifications should go beyond
present requirements and include the ability to digest
and stay ahead of new developments. Because of rapid changes in technology and the need for many specialists, corporate executives as well will be required
to increase their knowledge of automation.

Editor's Note: The demand for data processing
personnel is enormous and an ever increasing
shortage seems inevitable. A growing variety
of specialized services are becoming available,
which could make it more practical and economical to use outside specialists or services than
doing the whole job within the organization .

was designed for was not flexible enough to allow for
natural growth, it is usually the systems man who was
at fault. Yet the need for systems people is .so great
that programmers are often promoted to systems-level
positions where they are capable of making these exp ensive mistakes barely after completing their programming education. We know of one case where an
"analyst" at a large corporate installation generated
seven slightly different daily reports by using seven
different programs, each of which processed all the
company's tapes - an immense file which averaged
only 1%daily activity!
A major task, therefore, is to improve the quality of
systems analysis and design. Unfortunately, schools
and institutions providing systems courses cannot
create experienced systems people. A trainee can
speed up the learning process by diligently reading
professional literature and by exchanging ideas with
systems people in other companies - but there is no
su bstitute for on-the-job training. It is conceivable,
however, that a concentrated effort on the part of the
entire systems profession could increase the average
lifetime of a program from 18 to 27 months by 1975.
This would mean a theoretical reduction of 1,000;000
required programmers by 1975!

survey conducted a few years ago disclosed that the

In most instances only the larger companies can
afford an adequate systems staff. Not all not-so-Iarge
.companies have realized this yet, but it is nevertheless true. What is available to medium-sized and
smaller companies? .
A number of highly-qualified systems people, aware
of the great lack of systems experience in industry,
have started their own organizations. Many management consultants and even some accountants now
MODERN DATA/April 1970

provide their customers with some systems talent. Yet
we still frequently hear the argument that "it takes
years to learn how our company operates." Perhaps
so. But a systems service should not be engaged for a
three-week job or any other short term. It should be
contracted to provide a lasting association on a retainer or on-call basis. The service organization will outlive all systems people employed by companies and,
aside from providing systems design and analysis, can
be very helpful in improving internal programs.
The continuing shortage of qualified personnel and
resultant rapid turnover of programmers has made
many a company desperate and generated much disappointment. The loss to industry caused by job-hopping personnel is tremendous. This is another reason
why some companies turn to outside services.
We have come a long way since the initial services
in data processing became available. Some companies
have had poor experience with outside help, but the
reaction of most is favorable. The growing number of
systems firms certainly is a strong argument that they
provide a wanted service; today there are more than
a few data processing services discussing the possibility of taking over the entire day-to-day operation
of data processing departments on a fee basis. The
following aids, typical of those now being provided,
should be thoroughly evaluated where they could be
of benefit to a company.

SOFTWARE DEVELOPMENT ASSISTANCE

To have programming done by an outsider five years
ago was fairly uncommon, although the government
has long made extensive and efficient use of outside
software services for important programs like the development of the Polaris submarine and the Apollo
project. Today, however, the situation is quite
different. More companies are calling in assistance for
software development nowadays, not only during
peak periods or emergencies, but also on a continuing
basis. A time saving was initially the reason; in some
instances it proved to be an actual cost saving as' well.
Some software development companies provide assistance for scientific applications only; others concentrate on business applications. A number of specialty
companies exist within each group, e.g., production/ inventory control in the business area; linear
programming in the scientific area. Still, most software houses will accept business as well as scientific
MODERN DATAl April 1970

projects, and the larger houses have specialists with
exceptional skills in a variety of applications.

PROGRAM PACKAGES

Canned packages with options for a range of uses
have not yet gained the popularity they deserve.
Most data processing managers and supervisors still
prefer to solve all their problems within the company.
But they will typically accept as a matter of course a
manufacturer-supplied sort or merge program. When
such subjects as pre-programmed inventory controls
or sales analyses are brought up, a mountain of objections are voiced, presumably originating from management requirements. Yet management is often more
willing to spend a reasonable amount of money to
have control over 90% of the required data on short
notice than to wait two years to get 95% of the same
data. This is sound reasoning, since complicated packages like the ones mentioned often take a substantial
effort to develop and, by the time they are ready for
production, the original requirements may have
changed to such extent that not all of the data produced is still needed.
Before "unbundling," most computer manufacturers
supplied free program packages with their equipment. Enlightened executives now think twice before
ordering the latest-generation computer when they
discover the cost of making the new equipment productive and compare it with the cost of previous-generation equipment and widely-available software.
A large number of program packages have built-in
options to provide for a broad range of common and

a yardsti ck of th e value of the p ackage. A reliable

DATA PROCESS ING CENTERS

Data processing cente rs are no longer considered to
be a haven only for small companies which want th eir
payrolls , simple billing, and accounts receivable
procedures automated . Eve n the larger companies, including many with their own computer installations,
have discovered tha t it may b e profitable t o con tract
some of th eir opera ti ons to nearby service centers.
Some have even discovered that the computer center
around the corner can compete successfully with their
entire EDP operation.
D espite the fi erce competition b etween indep endents , and also within each group , most centers still
operate most economically b y selling a service p ackage ma ny times over. EDP centers are not payin g
suffi cient a ttenti on to providin g custom-made servi ces
as a long-ra nge obj ective, a field which could make
th em considerabl y more a ttractive.
On th e other hand , alth ough mos t of the centers'

payroll, billing, various accounting fu ncti ons, and inventory control, some ce nters are moving in the directi on of not-so-common applicati ons. Th ese include
hospital administrati on, edu ca ti onal servi ces, producti on control, sales analysis, a nd personnel recordkeeping.
D a ta processing managers may b e surprised how
well th e services of a local da ta processing center can
b e incorporated in their EDP operations.

TIME-SHARING SERV ICES

Heal-time centers with direct-response services constitute th e latest variation in data processing assistan ce. Tim e-sharing resources are predominantly used
in scientific applica tions, but th ey are increasingly
recognized as powerful management tools.
The d esign of real-time systems and the developm ent of fl ex ibl e programs for a variety of customers
is a compl ex task requirin g ma ny man years of effort
and experience. This explain s why most centers offer
onl y a limited number of servi ces. In addition to scientific a pplications , business servi ces offered range
from scheduling and accounting to inventory control
and typcsctting.
Since on-lin e service centers are th e forerunners of
the proposed information utilities, it would be
MODERN DATA / April 1970

b enefi cial for data processing managers to investigate
now how these user-oriented centers could contribute
to th eir operations.

EXCHANGE OF PROGRAMS

Due to the shortage of qualified personnel, the exchange and sale of programs is b ecoming more active
of late. Several indep endent companies have prepared ros ters of program exchange organizations and
catalogs of available application packages, and the
U.S. Patent Office recently sponsored a pilot project
to classify software by algorithm for the purpose of
de termining pa tent guidelines and establishing "prior
art." Such rosters and classifications will certainly
h elp to promote a more lively trade in this area. They
do not, however, obviate the need to examine criticall y the standards used and the quality of d ocumentation provided with each of the packages offered.

SUMMARY

Tbe need for programming and general assistance
vari es from company to company and from time to
time. Ma nagers of others responsible for data processing p erformance, who find it difficult to meet projected sch edul es, will do well to consider the aids discussed in this article. Listed in sequence of tbe dollar
volume of business, these aids are ;
• D ata Processing Centers;
• Software Development Assistance;
• Time-Sharing Services;
• Program Packages;
• Outside Systems Support;
• Exchange of Programs ..
As with any other outside help, the following steps
are recommended b efore definite arrangements are
made to use outside services;
1. Check up on th e reputation of the service firm and
. its management;

2. Make sure the individuals working on your projects are capable technicians and thoroughly understand the problem;
3. Start p ayments on the contract or agreement after
some visu al proof of progress has b een received;
4. Guard against costs in excess of original estimate.
Based on current expectations of continued growth,
we can look forward to an even wider variety of programming and general EDP services in the future in fact, we are only beginning to feel the effects of
"the great shortage."

COMPUTER SIGNAL PROCESSORS' CSP-30 SYSTEM
The only way to follow a good act is with a better one.

Signal Processors, Inc. of Burlington,
Mass. is a company dedicated to producing a
dedicated type of system: the high-speed signal processor. Founded in 1968 "for th e specific purpose of
designing and manufacturing digital systems for signal
processing," the company's single-mindedness and
sense of purpose has paid off well. Within a year of
incorporation, CSPI announced its first product, the
Compu-Signal System 3 (CSS -3), a fast and flexIble
"off-the-shelf" signal processing system complete with
software for real-time fast Fourier transforms ( FFTs),
convolutions, correlations, signal averaging and sampling, and a variety of time-series applications.

C

OMPUTER

ACT 1: THE CSS-3 SYSTEM
The CSS-3 was immediately successful. In addition
to providing the company with an early source of
revenue, it established CSPI's reputation as a company with "know-how" in an extremely complex field.
Orders for the CSS-3 were followed by requests for
specialized single- or multiple-task signal processors.
New personnel were taken on. Office and plant were
moved to larger quarters . The company also found
the CSS-3 to b e an excellent vehicle for developing
manufacturing skills and, by following up on its customers, gaining a first-hand picture of the market.

BETWEEN THE ACTS
To Dr. Edmund U. Cohler, President of Computer
Signal Processors , Inc., the CSS-3, a custom-configured package of subsystems, was part of an experiment to determine the feasibility of a more sophisticated "total" system he'd been thinking of ever since
leaving Sylvania Electric Corp. to found CSPI. While
a senior scientist at Sylvania (the highest scientific

position within the General Telephone structure),
Dr. Cohler had supervised the design and development of basic circuits and memories for military computers. Later, as manager of Sylvania's Advanced
T echniques Laboratory, he led groups in the developmen t of digital processors for communications. Dr.
Cohler's experience convinced him that: • A special
processor was required for the special demands of
high-speed signal processing; • It would have to b e
designed "from the ground up;" • H e could design it.
Dr. Cohler's combination of past accomplishments
and present ambition was irresistible, and he found
many in his team at Sylvania eager to join with him
in forming CSPI. Thus, the "total" signal processor
concept existed at th e time of the company's inception. In fact, even before the CSS-3 was available for
delivery, CSPI's capabilities brochure hinted of a
"second product" which promised to b e "more than
an order of magnitude faster."
MODERN DATA /Ap ril 1970

ACT 2: THE CSP-30 SYSTEM
TABLE 1 • CSP-30 MEMORY RATES

That "second product" is now available as the CompuSignal Processor-30 (CSP-30), an extremely fast (100
nanosecond basic cycle time), 16-bit, special-purpose
computer featuring both core and IC memories (see
Table 1). Since speed is unquestionably the most
important characteristic of real-tim e signal processors,
one would expect that the "from the ground up" approach taken in the design of the CSP-30 would
result in a system considerably faster than the more
"general" processors not designed primarily for signal
processing applications. We asked Mr. Andrew
Emery, CSPI's director of marketing, if he had any
b enchmark data to justify this assumption. Mr. Emery
provided us with Table 2, and assured us that the
figures were derived objectively.

APPLICA TIONS

A curious fact about signal processing systems is
that, while they qualify for "special-purpose" billing,
they are among the most "general" of "special-purpose" systems. Their range of applications includes:
Real-time seismic and oceanographic data acquisition;
j / High-speed, multi-channel process control;
j / Vibration and shock testing;
j / Spectrometric and other forms of chemical analysis;
j / Signal demodulation and digital filtering for radar
and radio communication;
j / Optical character recognition;
j / Image processing and enhancement;
j / Speech studies and acoustic measurements;
j / Biomedical monitoring and vital-data analysis.
j/

In short, any application that involves the acquisition
and analysis (processing) of raw source data (signals).
The CSP-30, by virtue of its fast data acquisition
rate (direct IC memory access from or to external
devices allows transferring up to 10 million 16-bit
woi·ds p er second) and processing speed (typically
3 million instructions per second), further extends
this range of applications by making it possible to
MODERN DATA/April 1970

utilize real-time processing techniques that were previously impossible or prohibitively costly. In addition, multiple dedicated applications are possible,
serially, because the CSP-30 is fast enough to compensate for the price in time usually required by software/ functional programming.
HARDWARE/SOFTWARE

The complete (basic) CSP-30, shown in Fig. 1, consists of the CP with 4K 16-bit words of core and 512
words of IC memory (expandable to 32K and 2K
words, respectively), two magnetic cassette drives
(the system provides for three), rack-mounted control panel (an optional console version has a deskmounted control panel), power supply, and freestanding KSR-35 teletypewriter. All versions of the
system are provided with complete utility and functional software, consisting of a loader, symbolic text
editor, debugging aid, stand-alone symbolic assembler, diagnostic and maintenance routines, at least
ten FFT programs, and more than a half-dozen miscellaneous programs for averaging, correlation, and
digital filtering.
The CSP-30's do-it-yourself instruction set consists
of 73 single-word and 55 double-word instructions ar149

SWAPPING VS. PAGING

Editor's Note: This article compares the nature
and characteri sti cs of swapping and paging
techniqu es for time-sharing. Swapping is
judged by the author to show greater promise
for efficient time-shared operation and to b e
more subject to improvement.

Th e problem that we address is one of efficiency.
The multiaccess approach makes the user more
efficient; multiprogrammin g makes the computer
more effi cient by permitting it to go to anoth er progra m wh en it gets "hung-up" on the one it is presently
pursuing.

WHAT MAKES SWITCHING OR PAGING NECESSARY?

PROCESSING MULTIPLE PROGRAMS

Swapping and p aging are both techniqu es for optimizin g the computer's central processing unit. Often,
it is also desirable to furnish th e computer to several
users, making it appear to each as thou gh he h ad
complete control of th e computer. For such application s, the computer is asked to give attention w ithin
a short peri od of tim e, say one second , to several programs; each may be large or small, short or lon g.
It is clear we are speaking of a multiprogramming
system, in whi ch several programs may reside in memory at the same time. This permits computation and
processin g to commutate among the programs momentarily. Multiaccess computing enables each of several users to see th e computer through a terminal
which, durin g his use, b elongs to him. Communication with th e terminal may be mediated by an
auxiliary computer. This allows infrequent execution
for a given user without undu e load on the main computer.

If the high-speed memory were infinitely large, it
co uld hold all programs being worked on in their entirety. Switching from one program to any other could
th en be done instantly. But memory is not infinite; so
we must look for some means to improve transition
amon g programs. In the discussion which follows, w e
make use of the foll owin g assumptions, which apply
to swapping and paging resp ectively : • memory is
large enough to hold any single program; • memory
is large enough t o hold significant pieces of all progmms being considered.

PAGING
ADVANTAGES

With p agin g, pieces of each program are contained in
memory with the most recent portion of any given
program immediately available when that program is
called upon. Thus, when the computer gets stuck it
can switch to the program of its choice without exp ecting any waiting. Certainly this technique favors
improvin g the computer's effici ency - even when I/ O
is unbalanced. Many programs frequently call upon
I/O without furth er work to be done until the call
is completed.

Dynamic Relocation Capability - One of the qualities of paging techniques is dynamic relocation.
Memory is divided into blocks (or multiples thereof)
of equal size. The program too is divided automatically into pieces or pages of the same size. The location that any page occupies is undetermined before
that page is brought into memory during running.
H ence it's location is unknown at compile time and
assembly time, and by the linkage editor and loader.
MODERN DATA/April 1970

The page is placed in the spot most advantageous to
overall computer operation. Thus, although page 7
may be placed in one position today, it may occupy
an entirely different position when it is run tomorrow .
More importantly, page 7 may b e moved around to
different positions even while the program is running.
Th e problems of making any page relocatable "on
the run" cou ld be solved, by either software or hardware. In the first case, software must intervene for
each and every reference that a program makes. Since
this lengthens the running time for every program by
a rath er large factor , most manufacturers use the
hardware approach to paging. But even with the good
and comparatively inexpensive solutions now being
provided by several manufacturers,l special software
must still be supplied for augmentation. Some
significant fraction of memory references requires
multiple memory cycles.
Thus, dynamic relocation, even when facilitating
hardware is supplied, increases running time by the
additional time required to locate positions on page.
Interpa ge Reference Frequency - With paging,
only one p age of a program is brought in at a time.
When that program needs another page of data, the
page is called for with a separate request. Thus as a
program runs, new requests continually arise for new
pages of both program and data. Each request is
turned over to the paging monitor, which finds an
empty spot to place th e incoming page.
Generally, however, memory is completely filled
with inform ation - there is no spot immediately available for th e new page. H ence room must b e made by
the paging monitor. When a suitable position is found
( a complicated task in its own right ), th e information
at that position may have to be saved. The paging
monitor checks into this.
The auxiliary memory monitor is responsible for
communication and transfer between main and auxiliary memories. It saves the old page when required,
and supervises the acquisition of the new page. Processing functions are resumed after the auxiliary
memory has initia ted the paging requ est.
To continu e processing, a priority monitor chooses
the next program to b e serviced. Service on the original program is suspended while paging proceeds via
the auxiliary memory monitor. The original program
won't get another turn until its page is brought in.
One difficulty which may arise: some of the pages of
the original program may get paged-out while it is

waiting for its new page; when it is reinstated, it may
find some of its old pages gone, thus facing a new
hang-up.
The originall y proposed procedure of requesting
th e single page might require revision to cope with
this problem. The present solutions to interpage references do not seem too satisfactory.
That interpage reference is truly a problem was
clearly demonstrated in an article by Fine, Jackson,
and McIsaac.~ For this study a computer with a memory of 64K was used. A page consisted of lK words.
There were approximately 48K useful pages available
in memory outside of those required for software. The
computer's instruction time was 1.6 microseconds exclusive of fetch. The authors found that 10 pages of
the program were generally required within 5.6 milliseconds of operation. They also noted that for programs requiring mOre than 20 pages of memory, at
least 20 pages were required within the first 7 milliseconds of operation. While this study did not consider
the need for paging-out, it did reveal the high rate of
interpaging references for the program. And this without conSidering the paging requirements of the data!
Paging Time - The actual time required to get information from the auxiliary memory is not negligible.
For the smaller disk units w e must consider a seek
time of 75 milliseconds, latency time of 25 milliseconds, and a transfer time of 25 milliseconds. At 125
milleseconds per page, it is possible to access only 8
pages p er second . It is important to note that in some
systems the program is completely paged to the disk
when communications between the computer and a
termin al is complete and the computer is awaiting a
new request from the terminal. This means that considerable paging time must be spent simply in reactivating programs, even when a user remains at his
terminal.
Of course, this is the least attractive case. Paging
tim e can be effectively reduced by the use of multiple
disk modul es with seek overlap. Another expedient is
the use of high-speed drums . In fact, with drums we
can in crease our rate up to one hundred pages per
second. But we still have the problem of bringing information from the disk to the drum . Present systems
require that the disk-to-drum transfer pass information through the main core memory. Such transfers,
then, require double access time: disk to memory;
memory to drum. This is done before the information
is actually required in main memory, which then calls

for another drum-to-memory transfer. This might be
improved by hardware means. 3
Paging Monitor - The paging monitor is most notable for its extensiveness. H ere is a brief list of some
of it tasks.
• It must frequently do look-ups in the page and signal tables.
• It fabricates and uses the drum monitor queues.
• It fabricates and uses disk monitor queues.
• It contains a disk and drum interrupt monitor.
• It must choose information from interrupts and the
page and Signal tables.
• It must monitor service for each of the terminals.
• It contains job and task tables together with priorities so that it may choose the next job for the computer.
• It provides a page-out monitor.
• It must manipulate and interchange priorities for
user and background tasks.
The paging monitor is extensive not only in the
number of tasks that it performs, but in its other qualities : • Size - the room in memory for programs to
do all these tasks is considerable; • Length of operation - for the IBM 360, Model 67, the time required
to perform all the functions associated with paging is
in the neighborhood of 1 to 2 milliseconds.

grams to slow down the reactivity of the system. This
certainly improves the total reaction time during a
given run over what it would be under paging.
DISADVANTAGES

Dedication - While a given program is running, only
it and the software occupy memory. The entire computer is d edicated to the program which has taken
over. Such applications as payroll or other EDP functions which are I/O-bound would meet with intolerable delays with this system. That is, without multiprogramming, unbalanced programs meet with
ineffici ent computer use.
Long Swap Time - 'When a program completes its
time slice or fini shes all the tasks assigned to it, a
swap is required. If a user needs a portion of a large
program for a few simple operations, this is unknown
to the system. Regardless of the predicted use of a
program, the entire program becomes resident in
memory an d the computer b ecomes dedicated during
this p eriod. Thus, a complete swap requiring fractions
of a second is necessary for even a few microseconds
of computing time.
User Limitation - Because of the long swap time required regardless of running time, the number of users
of a swap system b ecomes limited. If we were to p ermit a large number of terminals , queue length would
b ecome long and response time would deteriorate.
Swap Time Unmasked - Because multiprogramming
in its true sense is not available in this system, no
useful work is b eing done while swapping occurs. If
this were possible, the high swapping time would not
be intolerable.

SWAPPING
MULTIPROGRAM SWAPPING
ADVANTAGES

The program under swapping is always completely
contained in memory. H ence, during its time slice, it
never has to wait for the operating system to obtain
more program. Also, it is usually true that all the data
to be worked upon by the program is in main memory
with th e program.
Because of the on-line nature of the system, there is
generally very little holdup for input or output activity. Thus, users at terminals are either communicating
with an auxiliary computer or with a small real-time
monitor, which does not perceptibly impede the main
program. Or else the user has made an execution
request and is awaiting its completion. In all cases,
vast quantities of printed information are not characteristic of this system.
Because of the above characteristics, the time slice
allocated to a program is generally totally available
without option. New program information or data is
not required and h ence there are no holdups outside
of swapping itself when another program takes over.
A program uses up its time slice as a chunk or else
terminates its operation within its time slice. Since a
time slice is not split-up, there are no intervening pro154

A problem arises with the swapping teclmique on
programs which are I/O-bound. That is, when a
program gets stuck during input or output operations , that program no longer makes effective use of
the central processor. It can't swap out the program
while I/O for it is going on. Nor is there anything else
for th e central processor to do. Hence, for the time
slice assigned to this program, the central processor
becomes idle.
Why not several programs in the computer
memory at once? Then when we get stuck with
one program because of I/O assignments, we can
work on another program. The simple objection
to this solution is that often it is impossible to get
more than one program and the software into
memory at once. If we break up the program into
chunks, we are faced with the same probl em that
paging attempts to overcome.
Fragmentation Problem - Suppose programs are
small enough so that several can fit into memory at
once. This causes a serious problem when one or more
of the small programs terminates. The completed program leaves a hole in memory. This is fine if there is

another program of exactly the same size to fill up
this hole. If the waiting program is smaller than the
hole, we can fit it in, but we have left a smaller hole.
If the program awaiting service is larger than the
hole, we have to wait for a hole that size to develop.
If another hole develops , such that the total area is
enough to house the waiting program, we either have
to break it up into two smaller pieces, or wait for a
continuous hole of the right size to develop.
Finally, we have the case where several small and
large programs are mixed. This really creates a
difficulty.

IMPROVING PAGING

There are two main difficulties which arise in paging
techniques.
1. Frequently a program is faced with a missing page
which causes it to turn control over to the page monitor.
2. The page monitor requires a lot of space and t akes
up much needed computer running time to manipulate the many queues which are necessary to keep
track of what is going on.
MULTIPLE PAGES

Present proposals are to acquire a single page at a
time. If we were to try to get several pages, how
would we know which pages to get? We might get
successive pages such that if page 456 were requested,
it would also bring in pages 457, 458, etc. We could
not expect much h elp from this technique.
On the other hand, with the programmer or the
compiler we might have furth er information which
would suggest those pages which would be required
in the imm ediate future.
Thus the multiprogram solution is best approach ed
by enlisting the aid of th e compil er or the programmer especially in the case where assembly language is
being used.
PAGING MONITOR

W e can add sophistication to the paging monitor to
make it operate more efficiently, but only at the cost
of precious memory space. There is a trade-off. If the
paging monitor could improve the selection of pages
to b e paged-out, this might improve overall operating
efficiency.

FOREGROUND / BACKGROUND PROGRAMMING

The suggestion here is to have a computation-bound
program which requires a lot of computation and
little or no I/O activity in the background. The remainder of memory would be free to house foreground programs for the multiaccess user who gets
priority. But when his program gets stuck b ecause
I/O is going on, the central processor can be assigned
calcu lations for the background program. Further,
during swapping, the background program can also
be put into operation to make more efficient use of
time.
Note that this technique permits batch processing
to go on in the background with multiaccess users in
the foreground. The problem with this suggestion is
that now three entities occupy main memory:
1. The software and swapping monitors which must
be provided for;
2. The background program which is computerbound;
3. The multiaccess user program.
In general, this calls for larger memories than installations might bargain for. However, the increase in
effici ency should pay for the extra memory cost.
When the users' programs are small, this technique
is no problem; when the users' programs are very
large, the background program can b e swapped-out.
It is th e intermediate size which hurts us most.
PRE-SEGMENTED PROGRAMS

If eith er the translator or the programmer supplies
programs in chunks which are relatively independent
and of a reasonable size, this might help us to multiprogram. ' Ve cou ld then feed segments of several
programs into the memory at th e same time, and
switching withou t swapping would be possible. (Naturally we would rather switch than swap.)
Hol es may still arise. unless we can request of the
programmer or the translator that segments be of
fairly uniform size. Beyond that, aid may come from
either smarter monitor, occasional "garbage collection :~ and a fair amount of extended core memory.

EXTENDED CORE MEMORY

Large but slow core memories are becoming available
for use as auxiliary memories. Can such memories
help us with the multiaccess problem?
FOR PAGING

IMPROVING SWAPPING

With swapping there are two salient problems:
156

If we keep programs or data in an auxiliary memory,
whether it be core, disk, or drum, we still have the
MODERN DATAl April 1970

probl em of transferrin g the progra ms or data into the
main me mory fo r use. F uthermore, proposals whi ch
su ggest extend ed core memory as anoth er run g in the
ladder or heirarchy of memories present the prob lem
of gett ing info rm ation from one auxiliary memory to
a noth cr. Even though access to inform ation in exte nded core is much faster th an for disks or d rums the
transfer rate may be slower. In su mm ary, extend ed
core d oes no t seem to help us very mu ch with p agin g.
FOR SWAPP ING

It is possibl e to stack mu lti access fo reground programs in extended core. Th is would greatly red uce
swappin g time when small programs are involved .
Anoth er p oss ibility is to execute programs directly
within extended core. This would require longer execution time, but would entirely eliminate swappin g
tim e. Again w e are fa ced with trad e-offs in execution.
Should we have large programs like compilers in extended core for execution there; or should sm all foreground programs b e executed in extended core, reserving fast core for compilers and other large,
heavil y-used programs?

JOB STACKING

For a reasonably effective time-shared system, w e expect the job queue to contain jobs of several kinds :
few of them will b e data processing-type jobs in the
usual non-time-shared sense; some will b e machinelanguage programs generally of small size ready to
work on real data; many will refer to large, already
debugged programs, such as compilers, assemblers,
special translators , list processors, display programs,
and other service-type programs.
Now the p oint is this : suppose I have a Fortran job,
followed b y a small user job, follow ed by another Fortran job. If th ey enter the queue in this order, the
Fortran compiler will have to be paged-out for the
machine-language program and then swapped-in
again later. By al terin g the position of the second Fortran job in the queue, or by changing its priority, we
can save the double swapping of the very large Fortran comp iler. Certainly this or a similar technique
could improve the efficiency of both a paging or a
swapping system.

CONCLUSIONS

2. Queue management is necessarily a more important function for paging; it requires monitors
of larger size. These monitors take up more of the
computer's time than would be required in a
swapping system.
3. Swapping systems can be improved to mask
the time required in transfers from auxiliary to
main memory. This m eans that multiprogramming
is a necessity. This can be achieved through either
larger memories or segmented programs.
4. Extended core can help in both techniques,
but prob ably has a more telling effect upon
swapping.
5. The incorporation of automatic priority re-allocation can help in both techniques by eliminating
p agin g or swapping time for large programs used
by nonsequential jobs occupying the queue simultaneously.

. RESOLUTION PROGRAMMING
A powerful technique for allocating limited resources
THE STOCK ALLOCATION PROBLEM

Editor's Note: Many companies have installed computerized stock allocation systems: The William Carter Co . installed one of the first in 1960. In 1967,
Carter's implemented the technique described in this
article, and has since found it to be extremely successful in eliminating many disadvantages of traditional tape- and disk-oriented systems by providing
efficiencies in disk accesses, execution time, and core
requirements. The technique is sufficien tl y general so
that other applications are possible.

Resolution Programming is best described in relation
to the classical stock allocation problem. Basically,
this problem involves the allocation of limited stock
( inventory ) to a large number of competing customer
orders in such a way that:
condition a: Minimum order fill conditions
satisfied;
condition b: Order priorities are recognized;

are

condition c: Inventory use is maximized.
Programming" is the name for a very
powerful technique developed for use in our
computerized stock allocation system. It has provided,
with dramatic effect, up to 80% b etter utilization of
inventory than a form er computer allocation system .
Furthermore, we believe that the techniqu e is so simple, fl exibl e, and powerful that it may have wide application to other probl ems where limited resources
must be distributed or allocated to a large number of
competing demands. Examples:
"RESOLUTION

1. The allocation of classroom space (a limited resou1'ce) to student schedule demands;
2. The allocation of the capacities of a number of machines (limited resources) to different departmental
re quirements;
3. The allocation of limited manpower to competing
projects.
"Resolution Programming" is b est described by illustration . In gen eral terms , however, the following
fram ework will be helpful.

1. The inventories of the limited resources are
recorded on a random access file.
2. The orders (demands) which compete for the limited resources m'e recorded on a file (tape, cards, or
disk) and can be processed sequentially.
3. Since all orders or demands cannot be fully
satisfied (resow'ces are, by definition:, limited), the resources are allocated to the orders in such a way that
customer dissatisfaction is minimized and use of resources is maximized. (Extensive flexibility is available to define such things as lowest level for customer
satisfaction. )
158

Let us examine these more carefully . Note that
"limited" is emphasized ; that is, it is assumed there is
insufficient inventory to fill all customer orders. Condition a (minimum conditions must b e satisfied) says
th at a customer order for several or more items should
not b e "filled" unless a certain minimum is available.
For exampl e, if a customer orders ten different stock
items , company policy may say to fill the order only if
70% are available, or only if a minimum weight is
available, etc. Additionally, it is normally desirable to
bring as many orders as possible up to the minimum
fill condition ; that is, th e minimum should not b e exceeded unless no other order can use the stock to meet
its minimum.
Condition b (priorities) says that orders normally
have to be handled in some ranked sequence - for example, by date of receipt. Order priOrities may interrelate with condition a in some complex manner.
Condition c (inventory use) says that as much of
the available inven tory as possible must b e used in
accordance with conditions a and b.
The above, of course, are general rules which can
b e emphasized or de-emphasized in a given company.

TRADITIONAL SOLUTIONS

Many companies have installed stock allocation systems. These have generally been designed in eith er of
two ways.
Tape Systems - The magnetic tape order file is
sorted to item number sequence and matched against

an item mas ter inventory RIe. Inventory is allocated
by item as long as it "lasts." Th e order RI e is then
sorted back by order number and "fill / no fill " dec isions are mad e on each order.
Random Access Systems - The in ventory RIe is on
disk or other random access device. The order fil e,
from tape or disk, is passed against the inventory RIe,
order by order, in priority sequ ence. As each order is
comp leted, a "fill/ no fi ll" decision is made based on
th e items available and th e company's minimum order
fi ll co nditions. In more advanced systems, if a "no fill"
d ecisIOn is reached, the order is immediately reprocessed to put th e alloca ted stock back into inventory , thus making th e stock available for orders not
yet processed.
The disadvantage of th e tape system approach is
that it provides no practi cal way to put sto ck back
into inventory if an order does not meet minimum fill
conditions . Thus, as many orders as possible are not
brought to th e minimum condition and inventory use
is not maximized.
The trad itional random access system provides for
putting stock back, but does so very in effici ently. Th e

entire order is usually saved in core, thus imposing
some arbitrary maximum order size. All allocated
items must then have another access to the disk 6le to
correct the inventory, and the order is th en extracted
from core and written on the output device. In addition , the disk approach normally does not bring as
many orders as possible to th e minimum fill condition.

RESOLUTION PROGRAMMING

Resolution Programming has none of the disadvantages of the traditional tape and disk systems.
Indeed , it provides significant additional advantages
of great fl exibility, speed, and very small core requirements . Th ere are no artificially set maximum order
sizes (an ord er can b e for any number of items), and
th e techniqu e allows great flexibility in levels of order
priorities.
For convenience, Resolution Programming will be
described at three levels.
level J: Describ es th e w a y Resolution Programming
solves the p roblem of " putting stock back" ve ry efficiently .

level 2: Describes how level J can be modified so that
as man y orders as possible are b rought up to the minimum
fill condition; and how addil ional stock is then allocated.

level 3: Describes how order priorities can be established
with great flexibility .

Disk Record for Item

F or all three levels, it is assumed that the item
inventory file is on a disk (or other random access
device ) and the input and output order RIes are on
tape, cards, or disk. It is possible to access randomly
the disk record for an item by some direct or indirect
ad dressing techniqu e. It is also assumed that each order in the ord er fil e can be accessed sequ entially in
priority sequence.

Levell - "Putting Stock Back"

For this level, the disk record for each item must include two extra, initially blank, fields:
1. [LO (Identity of Last Order);
2. QLO (Quantity of Last Order).
In addition , this level requires that a portion of main
memory be set aside for a Decision Result Table
159

RESOLUTION PROGRAMMING ........ Co nt/d.

(DRT). One position of this table will b e assigned to
each order processed: the first position for the first
order; the second position for the second order; etc.
However, we shall show that the table may b e any
convenient size - it does not have to provide a number of positions equal to the number of orders to b e
processed.
Each order is processed one item at a time. For
each item, the disk record is accessed and the inventory field is tested to see if the quantity on th e
order is available. If it is available:
1. The inventory fi eld is redu ced by the ordered
quantity (stock is "allocated");
2. The ordered quantity is recorded in the QLO field;
3. The address of th e position in the D ecision Result
Table for this order is recorded in the ILO field ;
4. The ordered item is coded "allocated" and immediately written on the output card , tape, or disk;
5. The updated item inventory record is written back
to disk.

If sufficient inventory is not available, the order item
is coded "not allocated" and is written on the output
card, tape, or disk. Order level accumulators are updated showing number of items ordered, number allocated, number not allocated , etc., as required.
After all items for an order have been processed,
the order level accumu lators are examined to see if
minimum fill conditions have b een satisfied. If they
have, a "Y" is placed in th e D ecision Result Table in
th e position corresponding to the order. If minimum
fill conditions were not satisfied, an "N" is placed in
th e D ecision Result Table.
It is extremely important to note that stock is not
"put back" at this time if a "no fill" decision is
reached . Thus, the inventory fields for all items allocated on the order are "wrong." A fundamental concept of Resolution Programming is that an inventory
figu1'e need be correct only w hen the next order for
that item is processed. So w e wait until the next ord er
for an item is encountered and , as soon as the disk
record is read, th e inventory field is corrected before
stock availability for the new order is tested . This correction is accomplished easily by using ILO, QLO,
and the D ecision Result Table! The processing is simply: If ILO is not blank, check the position in the
DRT identified by the valu e in ILO. If it is "N"
(meaning this order was not filled) , add QLO back to
Inventory. If "Y" (meaning order was filled ), no adjustment is necessary. In either case, blank out ILO
and QLO.
The advantages of Levell are that:

a. Stock is "put back" with no extra disk accesses;
b. An order may be f01' any number of items;
c. As each item record in an order is processed, it
may be output immediately. There is no need to save
the entire order in memory.
160

As we stated previously, the DRT may be any convenient size. When all positions have been assigned to
in coming orders, and at the end of the run , the D ecision Result Table is simply resolved by an automatic
program interrupt which simulates an order for all
items on th e disk (or which does a disk search for all
positive ILO fi elds). The DRT is then blanked-out
and reused for the next set of orders.
Finally, note th at th e output fil e mu st b e reprocessed so tha t "fill ed" and "not fill ed" orders can b e
divided for appropriate subsequent processing. If the
fil e is on tape, a short record for each order on an
extra tape (or a punched card) can b e used as the
dividing trigger.

Level 2 - Bringing as many orders as possible to the
minimum fill condition

For illustration, assume that th e minimum fill condition is b ased on the number of different items ordered, e.g., the order will be fill ed if 50% of the numb cr of items ordered are available. F or this level also,
th e disk record must include extra, initially blank,
fields:

r

1. ILO lA . L
I1
2. QLO
S 111
eve
3. INO (Item Number)
Again, a D ecision Result Table is required . However, each order will now b e represented by one or
more consecutive positions in the DRT. Th e number
of positions will depend on the normal maximum
number of items an order might h ave. Let's assume
two positions ( up to 99 items) for each order.
Th e processin l! for Level 2 is th e same as for Level
1, except th at each item with stock allocated is numbered, first 01, second 02, etc. This number is recorded
in I NO and on the output order £Ie record for the
item. Thus, an output order may appear as follows :

should not be allocated until all other orders have
been processed. To accomplish this, an "04" is
recorded in the DRT. Now, when disk records for
items on that order are retrieved for future orders,
only those with an INO of "04" or less will have allocation confirmed. The allocation of the item with "05"
(Item No. 8414) will be reversed, making the stock
available for subsequent orders.
But what happens if no other order can use that
stock to reach a minimum condition? The stock can
be made to revert to this order simply by performing
a stock check again when the output order file is reprocessed to divide "fill" orders from "no fill" orders.
This requires that the value inserted in the DRT also
be written in the record which acts as the trigger to
divide "fill" from "no fill" orders.
Note that Level 2 will b e most effective if the
items on each order are in random sequence, since the
last items are th e ones held for future orders. Level 2,
therefore, provides a simple means of bringing as
many orders as possibl e to the minimum condition
and gives extra stock to th e highest priority orders.
Many refinements of Level 2 are possible, depending on overall system requirements and design . For
example:
Refinement 1. If the total demand, by item, of orders
to be processed is known before the run starts, each item
can be coded to indicate whether stock is adeauate for all
orders or not. Then the allocation process can be modified
to reverse allocation of stock in excess of the minimum for
limited items only.
Refinement 2. If the size of the order is known before
the first record of the order is processed , allocation may be
terminated as soon as the minimum is met. (Note, however,
this is in conflict with Refinement 7.)
Refinement 3. Simple techniques can guarantee that
coordinated items are shipped together. This is normally
an important consideration in stock allocation systems.
Refinement 4. A Run Switch can suppress the allocation
of stock in excess of the minimum fill condition.
Refinement 5 . The DRT may be bit-oriented instead of
character-oriented to save space.

(WARNING: Many analysts, at first glance, attempt
to improve the allocation concept by decrementing
the value inserted in the DRT a'S future references to
it are made. The reader can prove to himself why
this will not work.)

Level 3 - Ordinary Priority Levels
If an order file is large, it is normally impractical to

rank each order in priority sequence. Rather , a group
of orders may be considered to have approximately
162

the same priority. For example, all orders received last
week may be of the same priority and this may be
considered higher than the priority of orders received
this week.
L et us assume that the order file is in sequence by
priority and there is some way to identify the last
order at each priority. The number of priorities may
be as high as required. A requirement of the allocation system, then, may be to save enough stock to
cover all orders at priority 1 before allocating any
to orders in priority 2; next, to save enough stock
to cover all orders in the first and second priority before allocating any to orders in priority 3; etc. For
example, even if no orders in priorities 1 and 2 met
the minimum fill condition, the requirement for all
orders in these two groups would be protected from
orders in priority 3.
This is accomplished by a simple modification of
Level 2 Resolution Programming. Three additional
fields are required in each item's disk inventory
record:
1. GRPNO (Croup No . of Last Order)
2. DPG (Demand for all Previous Croup)
3. DCG (Demand for the Current Croup)
The processing is as follows: A "Croup No." is automatically assigned to each priority. Thus, orders in
the first priority are in Croup No. 01; orders in the
next priority are in Croup No. 02; etc. As a disk inventory record is accessed, and after previous allocation is confirmed or reversed, the Croup No. for the
current order is compared to the CRNPO field. If it is
higher:
1. Add DCC to DPC;
2. Zero DCC;
3. Insert the Current Croup No . into CRPNO.

If it is not higher, no extra steps are required.
Now, in order to allocate, stock must cover DPC as
well as the ordered quantity. That is , the demand for
all previous groups is simply subtracted from the
Stock Field for the allocation test. Finally, if allocation is not made (or is reversed ), the ordered quantity
(or QLO) is added to DCC.
VVe see, th en, th at Level 3 adds a significant dimension to Resolution Programming. Again, the addition al processing is insignificant and no extra disk accesses are required.

SUMMARY

Resolution Programming, so called because of the
concept of continuously resolving the Decision Result
Table, is a powerful concept which saves significant
computer time and memory. And, even more important, it provides far greater flexibility than other techniques.

HAS THE WELL RUN DRY?
The author takes a look at I.he (·!tnent market conditions and
the problems of raising venture capital for new firlns in the computer fi eld.

enture Capital is high risk money whi ch has traditionally come from wealthy individu als, pools
of family cap ital from such fa mil ies as th e Rockefellers, the Whitn eys, and th e Phippses, and from a few
pu blic fund s such as American Research & D evelopment ( ARD ). In the last two to three years, aggressive
money managers at both b anks and insurance comp anies have been putting a portion of their assets into
this area and are takin g a long-term outlook on th eir
commitment to the venture capital field.
A secondary source of money for the venture ca pital fi eld is the individu al in ves tor with a net worth
range of between one million and five million doll ars .
These people are norm all y in vestors in high risk situations with money which they h ave just mad e in the
stock market. For examp le, an individu al in this category mi ght have owned a stock such as University
Computing and watched it go from $20 to $160, taken
part of his profits from that inves tm ent and rein vested
th ose profits in a small software consulting firm , with
the thought th at he could find anoth er University
Computin g and b e one of th e origin al founders. The
avai lability of money from th is source is very much
contin gent upon th e performance of the overall stock
market, since norm ally such an indi vidual in vestor h as
limited experience in th e venture capital fi eld with
startin g small young co mpanics. If th e stock he holds
goes down, th e in vestor is hes itant to put additional
money into high risk start-up situa ti ons.
Thu s, th e avail abi lity of venture capital money h as
a grea tly accentu ated curve in relationship to th e
swin gs in th e stock markct. W ith this avail ability, th e
correspondin g terms of thi s money are grea tly accentu ated. The willin gness of the public to buy unseason ed comp anies in th e "new issue market" also tends
to accentu ate these flu ctu ations and to b eguile many
investors and management groups into a false assumption regarding the ease of raisin g mon ey.

V

CURRENT CONDITIONS

Th e market conditions of th e las t year have witn essed
a dramati c portrayal of th e aforementioned cycl e, particularly in th e computer industry. Th e investing community decided approxim ately two years ago that
companies in the computer fi eld could only grow and
be profitab le. H ence, th ey bid th e stocks of th e public
companies to ridiculous h eights and found mon ey for
th e creation of many compani es which should never
have b een in business. Within th e last six months , the
combination of tight mon ey, a fa lling stock market ,
failure for many of the companies to meet their pro164

jections, and a reversal of the inves tors' attitude will
likely precipitate a series of bankruptcies among small
compan ics in the computer fi eld. To wit, Scientific
Control Corp ., United Sys tems, Jonker, etc. The situation is very an alogous to th e sa me type of flu ctuation
th e electronics industry went through in 1961-1962.

CRITERIA FOR OBTAINING MONEY

E ve n und er th e adverse market condition s currently
ex isti ng, there is money availabl e in the venture capital fi eld for th e good management team with a
so undl y conceived idea . Th e foll owin g are th e major
criteria whi ch a venture capital inves tor wishes to
cvaluate. Th e first and mos t importa nt criteri on is the
quality and track record of th e management team .
Wh at have th ey done before? D o th ey have within
th eir group th e co mplemcntary skills of management,
technical kn ow-h ow, and marketing?
Secondl y, how uniqu e is the idea? To wh at extent
ca n it be protected from someone else duplica ting
wha t th e company is doin g?
Third ly, how well has the co mpany thought out the
probl ems of accomplishin g its venture?
Th e in vcs tor prefers to ohtain a proposal from th e
management tea m which in cludes an expl anation of
th e idca, fin ancial p ro jections, and detailed resum es
on the prin cipals. In this ins tance, th e investor is principall y intercs ted in th e reasons for the numbers in
th e fin ancial projections.

SOURCES OF ADVICE

sources of advice regarding financial affairs and the
raising of capital. Your accountants are frequently in
touch with p eople who either have money or who
know of sources of money. In addition, your banker
and your lawyer should be asked for advice in this
area .
The following are the criteria the management of
the company should weigh in deciding from whom
they will obtain the capital.
• The source of money should be professional investors in the venture capital field. In other words,
they should already have don e several high risk investments over the past three to four years. Eight out
of ten venture capital investments either go bankrupt
or get merged out under unfavorable terms and it is
important that your investors be familiar with the
problems of this area and the risks involved. Unfortunately, many of the wealthy individuals, who are
playing with extra money in the stock market, assume
that if Company X could start with one thousand dollars, you certainly should be successful with one hundred thousand dollars .
The second reason for dealing with professional
venture capital investors is that they are aware that
they will probably have to put up additional money
and are prepared to do so. This is not to say professional venture capital investors always put up more
money, but they are normally in a better position to
evaluate the mistakes and to be constructive with suggestions as well as money. Because these p eople are
usually exposed to a much wider range of investment
alternatives, they are more selective and frequently
require more advantageous terms than the less sophisticated investors. The management team has to weigh
this differential of terms against the more professional
approach of the venture capital investor to management problems, along with the additional ease of raising money at a later date once there is a recognized
professional investor in your company.
• Important also is how comfortable you feel with
your investors. The relationship between the investor
in a small privately-held company and the management team is somewhat analogous to being married.
Both parties are forced to go through many trials and
tribulations together but there is enough room for disagreement in the explanation of missed projections,
incompl ete financials , incomplete information regarding management, without the additional complication
of mistrust on either party's side. Because eight out of
ten venture capital situations have difficulties, the
management team is in the position of explaining why
they didn't make their projections. There is an obvious need on the investor's side for confidence, honesty, and forthrightness of the management. There is
an equal need for trust in the opposite direction because as the company acquires additional capital,
managem ent should not feel that it is being taken adMODERN DATA/April 1970

vantage of. Obviously, if the company has missed projections and run out of money, it is in a very poor
negotiating position in terms of additional capital.
EVALUATION OF TERMS

In searching for money, the management team has to
consider not only from whom it will obtain its capital,
but under what terms; i.e., what percentage of the
company will they give up for the money. The answers to these questions are generally a function of
the overall psychology of the market and particularly
a function of the specific investing group toward your
project. Along with the question of what percentage
of the company is the corollary problem of the financing s tructure of the company. Do you issue warrants
to purchase the stock at a slightly higher price in the
future? Is the stock held in escrow under a performance contingency for the management? Is there a
right of first refusal for future financings for the investing group? The structure of these options can
have serious implications for the next stage of financing, and therefore should be carefully thought out
by the management of the company and advisors.
When we previously discussed sources of advice
and mentioned accountants, lawyers, and bankers, we
failed to include a third group who are the people
whose profession it is to advise young companies
specifically on these problems. These people, or
groups of people, frequently are retained by the company to (a) advise it on the financing structure, and
( b ) locate the money for the company. These people
have the advantage of knowing the implications of
various alternative financing structures and can advise
the company on such implications, different alternatives in terms of future financings , as well as considering alternatives which might be more saleable under the current market conditions.
These p eople are alternatively called promoters,
finders, consultants, and several other non-printable
terms. It is normally to the company's advantage to
pay them in a combination of cash and stock warrants
to in sure their continued interest and advice. The best
way to evaluate the professional money raiser is analogous to one's criteria for the investing group. Management should be comfortable with the person on a
personal basis and should be familiar with one or two
of his previous financings and his current relationships
with those companies.
SUMMARY

The current market conditions make it difficult for obtaining venture capital, but money is available, and
the potential gains on successful projects in the computer field are still very obvious to the members of the
financial community.

A· UNIVERSAL FRONT-END CONTROL SYSTEM
Dynelec announces a processor/ concentrator for a wide range of communications applications.

T

he. new DyneMaCC 90 Multiple-access Communications Controller from Dynelec Systems Corp . .
of Glen Rock, N.J. is a universal front-end control
system desigNed to achieve maximum utilization of
communications lines with a minimum of main (EDP)
storage and in a minimum amount of processor time.
A hybrid communications system employing techniques of direct-line connection, multiplexing, and
store-and-forward switching, the DyneMaCC 90 can
be structured to take over a few or all of the communications functions of the central processor, and is
adaptable to the I/O channels of all major computers,
emulating standard periphal devices.

Fig . I The DyneMaCC
90 mult i-access communicatio n. contr oller.

CAPACITY

A large single DyneMaCC 90 system offers up to 220
ports for local low-speed data terminals, each capable
of handling input at rates from 4.5 to 300 bps. It also
offers 48 full-duplex ports for asynchronous and synchronous lines. Twelve of these ports can concentrate
64 low-speed lines each, for a total of 768. The other
36 are for conventional voice-grade lines at rates from
1200 to 4800 bps. Thus, total capacity for this
configuration is 1024 lines - although a typical system
would probably terminate about 220 low-speed ports,
both local and remote.

THROUGHPUT

In handling concentrated low-speed data from remote
terminals, a DyneMaCC/ DyneCoM (coNcentrating
multiplexer) trunk system is said to be 6 to 10 times
as efficient as a typical character-TDM .system. With a
DyneCoM 70 multiplexer used to COnnect remote terminals to the DyneMaCC 90 communications processor, the system becomes, in effect, an asynchronous
multipleNer under program control.

COMMUNJCATIONS PROCESSOR

Within the communications processor, the DyneMaCC can either transfer small blocks (the processor
handles each character) where instantaneous character responses are required, or, with special line termination units, can use hardware to inform the software
when a large enough block ,·of characters has been
created to effect transfer to the computer I/O (mux
channel). Software provided for the communication
processor includes a two-pass symbolic assembler, a
166

Fortran compiler, diagnostic and debugging packages,
and a library of miscellaneous subroutines.

FRONT-END CAPABILITY

As a front-end, the DyneMaCC operates similarly to
the mainframe peripheral being emulated. However,
it incorporates extensions to peripheral buffering in
the form of a disk and memory hierarchy that allows
the blocking of messages and the storage and switching of traffic for load-levelling a multiple-center data
communications system.

MODULARITY-FLEXIBILITY

The DyneCoM's modularity makes it easily and
quickly expandable from a fixed-program · unit to a
fully-programmable system. Its flexibility permits it to
be used both for reducing communications costs by
enabling greater concentration of line data; and increasing overall system performance by relieVing the
central computer of communications "housekeeping."
With over 50% of all computers expected to find their
way into a communications environment before the
end of this decade, the DyneMaCC system should be
welcomed as an excellent one-package solution to
what is fast becoming a universal problem.

PROGRAMMING LANGUAGES: History and Fundamentals
Author: Jean E. Sammet

PROGRAMMING LANGUAGE9: HISTORY AND FUNDAMENTALS

By Jean E. Sammet. 785 pp. Prentice- Hall , Engl ewood, N.J .;
$13 .50 (studen t's ed ition); $18.00 (cioth) .

An essenti al aspect of hoth profess ionalism and job effecti veness is the ability to apply a va ri ety of tools to th e solution of a
given problem. The principle tool for th e u se of computers is
the programming language. A programm er or systems analyst
who claims knowl edge of only one or a few similar languages
lacks the tool-kit which distinguishes professionals from technicians. Besides th e reference manual for th e language his current assignm ent involves, every profess ion al should place a
copy of PROGRAMMING LANGUAGES: HISTORY AND
FUNDAMENTALS on hi s bookshelf.
There is almost certainly only one fully-qualified reviewer
for this book. Unfortunately, th e author, Mi ss Jean E. Sammet,
must b e disq ualified. H er PROGRAMMING LANG UAGES ,
w ith 785 pages covering nea rl y 120 di stinct programmin g languages, is unquestionably th e m ost ambitious survey of its kind
yet undertaken.
Sup erlatives slide from th e pen - uniqu e, unparalleled ,
monumental, d efinitive, compreh ensive. To b egin at th e end
with th e co nclu sion , this revi ewer would have to rate this book
as an ahsolutely essential part of th e personal library of every
serious programmer and systems analyst.
The book is carefully and sys temati call y organized . The introdu ctory ch ap ters cons titu te a capsule introdu ction to what
programming langua ges are about (I h es itate to say programmin g lin guisti cs ), and a plan is laid for discussion of th e nontechni cal ( fu ncti onal, e nviro nm ental ) and techni cal ( syntactic,
semanti c, and pragmati c) aspects of each language.
In many cascs, the environ ment in whi ch th e language
emerged , in whi ch it is used, and its evolutiona ry progress are
essenti al to und erstandin g why a language ex ists as it does as
well as its d iffcrences from o th er la ng uages . To parapllrase
Fran k Lloyd Wri ght, intent clarifies form. Thc hi stori es th cmselves are worthwhile, as Miss Sam met debunks mu ch co mpu ter myth ology and injec ts amusin g new insights of h er own.
The introd uction alone is worth th e price of admi ssion, and
lang uagc des ig ners and impl ementers should b e required to
memorize it, since many of Miss Sammet's underl yin g sim plifica tions are either unknown or ignored hy om li ngu ists. It
has been a stanel of thi s rev iewer th at different programm in g
languages actu all y are not so d ifferent : th at most ( but not all )
are varia ti ons on a common th eme. Once thi s th eme is recognized, und erstand ing a spec ific language ca n b e quite simple .
The introd uction not only exhausti vely lists th e essenti al eleme nts of programming lan guages (e ighteen classes of statements and tcn classes of data are defin ed and described , for
exampl e), but defin es th e important dim ensions (succi nctn ess,
form ality, etc.) by wh ich langu ages can differ.
Miss Samm et groups th e book's langu ages functionally for
detail ed exa mination , i.e., by prin cipal applica tion. This organiza tion yi elds chap ters on languages for numeri cal compu tation ( e.g. FORTRAN, ALGOL); for formula manipulation
(e.g. FORMAC, AL TRON) ; for strin g and list processing (e.g.
LISP, SNOBOL) ; and for special and multipurpose appli168

ca tion s. Only JOVIAL, PL/l , Formula ALGOL, and LISP 2
are classified as multi-purpose, although AED aDd EULER are
equally valid ca ndidates. The author provides a remarkably
perceptive view of the practical problems of lan guage use in
th ese d iverse areas, and d escribes each lmiguage in terms of its
unusual or exceptional fea tures and in contras t with other lang uages. The inclusion of langua ges of historical interest not
only shows us progress, but regress ion: some valu able features
and faCilities, and some "neat tricks" h ave been forgotten.
Th ere is certain to be major criti cism for the author's d efinition of programming languages and her use of it as a basis for
in clusion or exclusion. The co ntroversial issue is h er insistence
tha t a programmin g language must b e "free form ," thus eliminatin g RPC and DET AB-X, for example. From a theoreti cal
standpo int, this criterion mu st be regard ed as completely arbitrary, ,sin ce essentiall y, it enables discussing only languages
wi th a one-dimensional syntax. This weakness b ecom es apparent in that Miss Sammet cannot h elp violatin g her own rule:
almos t all th e languages included , particularly FORTRAN and
COBOL, have some Rxed-form elements, and one sh e includes
( IPL-V ) is by her own d efinition certainly not a programming
langu age . Packages and embedded languages ( e.g., SLIP and
METEOR) , however, are justifi ably excluded by almost any
definition.
There are systemati c interrelationships b etween free- and
fi xed-form at interfaces, subroutine and program packages, and
imbedd ed langua ge systems. The common elements and structure of thi s ( unn amed) larger fi eld of discourse are skirted and
som ewh at muddi ed b y her definitions. This is an area on which
th ere is need for definitive discussion , and the work of D oug
Hoss, and thi s reviewer's work IntegmZ Ha.rdwa:re/ Softwa.re D esig n (MODEHN DAT A, April '68-Feb. '69) have b een attempts to
co nfro nt some of th e issues.
The copy supplied for review h ad numerou s typographical
errors, too m any even to take the time to ca talog. But these
errors were either non essential or obvious, and later copies will
undoubtedly remed y them . In general, th e language d escripti ons were felt to b e accurate and compl ete in th e b aker's
dozen cases where this rcviewcr could com ment.
One of th e mos t valuabl e fea tures of thi s book is its "Ancillary Con tents," whi ch references nea rly 600 bibliographic
entri es a nd rep resen ts nea rly all th e esse ntial, useful or, in
some cases, only works 6n langua ges covered. Subject, language, and au thor indexes are also provided , and one can find
all the machi nes for w hi ch a system presently h as b een implemented. The Language Su mm ary describes each language in a
sentcnce, cites the releva nt section, an d gives th e one or two
bes t references .
F or th e practi cin g programmer, PROGRAMMING LANGUAGES : HISTORY AND F UNDAMENTALS is an invalu able qui ck reference to mos t of th e languages h e will encounter. ( In many cases, th e superior programmer with varied
lang uagc experience ca n b egin coding solely on th e basis of the
brief descriptions.) For th e sys tems analyst and designer, the
book provides sufficient m ateri al for com paring and selecting
lang uages. Miss Samm et is to b e congratulated for havin g assem bled th e fir st side-by-side source of virtually all important
programm in g languages.

(Series 1100 or 6400) , a multiplexer, and up to 7 tape handlers. In
addition to routine keyboard data
entry, the 9200 system will convert
punched cards and punched paper
tape data to magnetic tape data.
Batch totals can be proven on a
keyboard/adding machine unit,
then centralized on tape. Data
transmitted over long-distance telephone lines can be processed
through the system to central tape.
Magnetic tape data can be printed
out on an MDS line printer. Keyentered data goes from the DataRecorder to a 9202 control multiplexer that transmits the data to
one of as many as seven 9207 or
9209 buffered tape handlers which
record the information on magnetic
tape. (The 7-channel 1100 DataRecorders transmit to 9207 tape
'handlers which record the data in
BCD code on 7-channel, 800 bpi
tape; the 9-channel 6400 DataRecorders use the 9209 handlers
that write in ASCII code on 9channel tape.) Any Data-Recorder
can be assigned to any of the tape
handlers. Mohawk Data Sciences

That's a modem made by Sangamoa major supplier of modems to the
telephone industry. Sangamodems are
compatible in all respects with their
Bell counterparts.
Because of a recent FCC ruling,
data users can now attach their own
modems to the DOD (direct distance
dial) telephone network via a data
access arrangement. Now there is a
new family of Sangamodems for use
through the data access arrangement
... manual or automatic answer.
Using a Sangamodem through a
data access arrangement lets your
business machine talk to the tens of
thousands of like telephone company
modems already installed, therefore
permitting an orderly transition from
lease to purchase.
If you have a phone-company provided 201, 202 or 103 and are considering purchasing vs. leasing, call
Sangamo, the people who make both,
to insure a compatible operational
system.

Smoke signals are fine for giving the
Indian sign . They' re far too slow for
pow-wowing with a remote computer. Still , there are people using
puff-at-a-time, typewriterlike devices
that take many moons to complete
printouts . .. while computer time is
elapsing and running up the bill.

Typeliner is the all new term ina!
printer that brings remote data
printers out of the pioneer age. It has
space age specs like 100 lines per
minute , ASCII 64 character set,
plug-to-plug compatibility with CRT
display terminals and modems.
And it is qu iet. Our Typeliner
doesn 't make war whoops every time
it prints. We 've designed a totally
new mechanism for minimal noise
and even gone to the trouble of
turning off the cooling fan during
standby mode.
Lines of crisp character type in
multiple copies are produced by
Typeliner's un iqu e Crosspoint print
head . With few moving parts , this
head prints clear, easily readable
text, yet needs only minimal
maintenance.

Very little wampum rents the
Typeliner. You can have one for
$245.00 per month with delivery
within 90 days. And you needn 't
worry about service. The Typeliner
was designed to shrug off maintenance that other mechanical
marvels require.

Don 't have to say " Yes" too often whe n
in 3 short years you c an go f rom one
mode l wi t h a TTY to a lin e of six models
with comp lete peri pheral capab ility from one office to a wor ldwide service
and marketing network - from the only
3rd generation small computer manufacturer to being the leader in a growing field.
In 3 short years you can build up a lot
of applications software , an unmatched Firmware library, train a lot
of users and maintenance people, ship
hundreds of computers at competitive
prices.
So what 's the new " Yes " ? Couple of
new computers. You can see them at
Booth 700 at SJCC. They will cause as
big a stir as the first time the committee said " Yes."
