OPS.CMD Modification
Tony Gandy Systeme Corporation 3443 Parkway Center Court, Orlando, FL 32804
Enclosed please find a copy of the command file OPS.CMD. Th.is is a modification of the command file submitted by Ralph Stamerjohn in the April '83 issue. <Editor's Note: April '83 Paqes 127-128) The primary chanqe was to limit the number of command strinqs supported and move the parsinq up front to remove redundant parsinq of each line from the sort file. As a result, OPS runs faster, especially on RSX-llM where Indirect is heavily overlaid. Additionally, OPS may create a command file without executing it, allowing further editing or reuse.

Manipulating the FORTRAN Environment

Although we are primarily a FORTRAN shop, we occasionally make small forays into the cryptic world of MACRO in order to enhance the FORTRAN environment. Presented here are three of my favorite little MACRO subroutines
1. SWERLN - Switch Error LUN
This routine re-assigns the LUN that FORTRAN used for logging any errors it happens to find. We direct it to the CO: device. This is particularly usefull for obtaining hard copies of errors and also, if you are using FORMS 11, prevents garbage from being spread all over your form .

2.Function:

2. IVAL - Return value of Global symbol or run time address
As its name implies, this routine returns the value of a global symbol (declared with GLBDEF task builder option> or the address of a FORTRAN variable. In this
manner, it works much like the GETADR subroutine. We use it for reading options set at task build time and some times for setting addresses of FORTRAN variables
for Executive services calls .

a global symbol delclared in an EXTERNAL statement.

; Return
3. GETARG - Return number of calling parameters
This little routine allows you to determine how many arguments were passed to a
subroutine. It must be the first call upon entry to the routine; don't ask me
how it works
it was empirically designed !

Many (if not most) users resolutely refuse to clear the terminal screen or dispose of
paper when loqqinq off. This may pose a problem at installations which handle confidential or proprietary information. The followinq subroutine hooks into BYE to automatically clear screens and/or remind users to remove their paper. See comments for installation notes ·
. TITLE BYESUB
.ENABLE LC
User subroutine to hook into ... BYE. The purpose is to automatically erase screen of a softcopy terminal or to perform paqefeed on a hardcopy terminal at loqoff time, in order to prevent unauthorized access to data shown on the terminal.
Notes: <ll This subroutine is hardware dependent and must be modified to use at other installations. The modifications required are to examine the terminal-type byte in
RO for those terminals present at the installation and to add messaqe and screen-erase strinqs for these terminals. In the present case, the only terminal types which exist are Tektronix 4014, TI Silent-700 and DEC VTlOO and LA120. The SET /TERM=ttn:m Cm = model number, 128-255) command is used at startup time to define the Tektronix terminals as m=l29 and the TI terminals as m=l30. See DEC documentation for lists of known terminals and their symbolic names and screen-erase strinqs.
See terminal documentation for non - DEC terminals.
<2> BYE assiqns LUNs 1 and 7 to TI:. Th.is subroutine uses LUN 1 and EFN 1 for terminal I/O.
(3) SY:[l,24lBYEBLD.CMD contains documentation on includinq this subroutine.

RSX-llM V4.1 SYSGEN Symbols
Dick Ba.ker-Munton Systime Computers Limited
Systime House 15/23 Baches Street. London Nl
Hhen RSX-UM V3.2 appeared. I subaitted a "Road Hap" of RSXMC.HAC symbols in Auqust 1980 which was published in Ih!:. Hµlti-Tasker. The enclosure is the equivalent for the V4.l release. which you miqht like to publish in your next newsletter.
The Cll,lOlRSXMCO.HAC and C200,200l~.CMD from RSXM35 and EXCPRV volumes of RL01/RL02 distribution kit were concatenated into one file. All lines with "$$" were extracted, sorted eliainatinq duplicates and formatted usinq TECO. The result is a definitive directory of symbols that may be included in the RSXMC.MAC prefix file qenerated by SYSGEN.
Other symbols may be found in the Cll,lOl~.MAC source files. These relate to options no lonqer supported (i.e. cannot be enabled by a straiqht SYSGEN> or for unbundled products or RSX-llM+ to I&D space etc. not supported under llM>.
Any more information can be obtained from me at Systime's London Office as above.

DECUS Library Update
Ardath A. Hassler The Catholic Universitv of America

Reported by Phil Beene DECUS Scribe Service
DECUS Spring '83 Symposium St. Louis. MO
Ms. Ardoth Hassler. library coordinator for the DECUS Library Board. led an informative working session designed to
update interested users on DECUS Library activities.
Following her brief status report on how
the Library has been operating since the
previous
DECUS
Symposium.
SIG
representatives from the U.S. Program
Library Committee delivered short reports
on how their individual groups are
progressing.
Ardoth began her report by explaining the DECUS Library's new incentive/reward
program to encourage program contributions from DECUS users. Any member contributing a program will receive a plaque from the Library acknowledging their efforts. Although announcement brought a general sense of approval from members of the audience, many thought the program would be more successful if the contributor were
offered the alternative of receiving credit towards one of the Library's existing

listed proqraaa. This suqqestion will be referred to the Library co. .ittee.
FollowincJ Ardoth'a announcements, Larry Hicks qave a brief report on his work with the Library cataloq. Since the last Symposium, the previous three exiatinq versions of the cataloq have been compiled toqether into one document. A free copy of this new version should be mailed to all DECUS aelll>ers around June.
The Library will beqin treating this cataloq as its main marketing tool. It will be given away in order to make more DECUS melll>ers and others aware of the wide selection of proqrams available through the Library System.
In addition to the cataloq distribution the Library will continue to improve user awareness throuqh posters, buttons, booth displays and the implementation of advertising.
A discussion of the Library's current taping proqrams and strategies elicited considerable input from members of the audience. One suggestion which came up during this portion of the discussion was the Library's need to make a better general abstract listing of available tapes and the information contained within them. The point brouqht up, was that many potential Library customers can't justify the tape purchase price without a better knowledge of what they are buying. Ardoth said the group would consider this in the future and try to come up with a better list.
Another taping problem currently being experienced by the Library is their need for a better copying system. A new mass-producing copying unit is one of the Library's main immediate objectives.
For those users and SIG members unable to attend the Symposium, or just wishing to obtain copies of SIG sessions, master tapes will be available. SIGs having copies made at the St. Louis Symposium included: RSX, RT-11, DECsystem-10/20, VAX, and RSTS.
Copies of these tapes are available to users for about $112. The RSX and VAX tapes are quite lengthy, and are expected to include two tapes.
The last portion of the formal half of the session included a discussion of long range planning goals. The main Library goal is to acquire a method of determining what items and interests users will have in the future. According to committee members, this knowledge will enable the Library to better plan and prepare for these needs, saving everybody time and money in the future.
Following the formal first half of the session, Ardoth and other co. .ittee members took questions from the audience.
Many of the questions concerned the alternative methods available to create Library donor incentives. Moat DECUS members present agreed a credit systea would be aore effective than the current plaque proposal. Citing other successful library programs, even Ardath agreed, but said she was not certain such a proqram would work in the DECUS system. She feels the Library could easily become overwhelmed with nonusable programs offered by users wanting free proqrams. Although the DECUS Library is not a profit organization, she said such results could destroy the system's financial stability through increased operating costs.
One alternative to the plaque system already being discussed, is the possibility of offering a RAINBOW 100 system through a lottery which would include all program contributors.
In other pertinent discussion, some users
felt that DECOS should obtain stronger
rules applying to users' copying and
distribution of proqrams obtained through
the library. Though there is no law which
protects the programs, which are public
property, members said it would be nice if
DECOS created a head or logo least
recognize their contributions to program
users.
This would not only be
self-rewarding to the program authors, but
would also create a greater awareness among
non-DECOS programmers.
In concluding the meeting, Ardoth promised all suggestions would be carefully discussed among Library managers, and promised to let users know results of these discussions as soon as possible.

Reported by Marc Caffee DECUS Scribe Service
DECUS Spring '83 Symposium St. Louis, MO
The purpose of this session was to have
reports from individuals who have field
tested the soon to be released versions of
RSX and RMS.
Both favorable and
unfavorable features were discussed.
For RSX-llM V4.l the first consideration was the ease with which the system was generated. There were no unexpected crash problems. RMS V2.0 works as advertised, in particular there is transparent file access through DECnet. It is worth noting that to incorporate this feature you need lengthy overlays or 32 KB of memory dedicated. Additionally, the system can now be "dynamically" tuned using MCR commands.
Among some of the disappointments was
essentially the same EDT as in V4.0. The
latest word on V3.0 of EDT is that it might be on the first update of RSX-llM 4.1 and RMS 2.1 It was also observed that TKB died occasionally for apparently unknown reason. In the 4.1 version IQ.X was removed. It was felt that despite it not working properly in 4.0 it was still better than nothinq.
At least one panel member was distressed by the direction of this new version. Hh.ile V4.l is iaproved in terms of maintenance it appears there are no real substantial improveaents to facilitate better realtime coaputinq applications, vectored FCS library for example. Also it would be desirable to see more uniformity for installation of layered products. Another improveaent miqht be a vectored executive.
In summarl, V4.l is better than nothing but not what t could have been.
Some of the features incorporated in RSX-llM-PLUS are:
1. A new version of the overlay runtime support.
2. 700 bytes of binary pool savings.
'3 · A large version of FllACP is now automatically multiuser.
4. There is now OPEN support for I-D space tasks.
5. ODT can look at both I-D parts of tasks.
Additionally an improved version of BRU is incorporated into both V4.l and V2.l. This version of BRU is upward compatible. It is not downward compatible. Features in the new BRU include the ability to backup to smaller sized volumes. If you run out of room on the smaller volume BRU asks you to mount the next volume. Also there is a new
R.P. sort algorithm.
The new version of RMS will have stream file support. Other features include use of wildcards and resident clusterable libraries in order to save space. In summary, the new version of RMS will essentially have the functionality of VAX
RMS.
Q. What will be the difference in
performance between FCS and RMS?
A. FCS can be faster using multibuffering,
but RMS does have more functionality.
Q. Hh.at are the updates we've been hearing
about?
Will these replace the
autopatches?
A. Updates will replace autopatches.
Hopefully, they will be better.
Q. Is a new I/O operations manual in the
making?
A. Not to anyone's knowledge. The RMS
manual has undergone major change.
Q. Hill current Fortran compilers work in
I-D space?
A. F77 will work, F4P will not.
Q. RMSLIB will be a vectored library.
Hh.at about other libraries?
A. He are workinq towards task independent
libraries.

A. 40 K with indexing, 20 K without. Q. Using RSX-llM-PLUS with many terminals

A. We believe this will no longer be a problem
Q. Will TKB run in I-D space? A. Yes Q. Will the distribution kit be in BRU
format?
A. Yes Q. What about EDT? A. Some minor changes have been made but
nothing major until V3.0 of EDT is released.
Q. Will all tasks linked to resident libraries in V4.0 and V2.l have to be rebuilt?

RSX-llM-PLUS for the Micro/PDP-11
Brian McCarthy Digital Equipment Corporation
Nashua, NH
S. Reid Madsen, Session Chairperson Weidner Communications
Menlo Park, CA
Reported by Marc Caffee DECUS Scribe Service
This session dealt with future plans for
support of RSX-llM-PLUS for the
Micro/PDP-11.
The basic
problems
encountered in RSX include difficulties in
installation management and the lack of
speed in TKB.
The basic challenge is to overcome the above problems so that Micro/PDP-ll's
running RSX can be utilized in small applications. Constraints encountered in meeting the above challenge are reduced cost for software, new distribution media requirements, ease of installation, reduced operating costs, and availability of
applications.
Some of the goals for future Micro/PDP-11 systems running RSX are as follows:
1. A system the customer can install within 1 hour.
2. A system which is easy to use.
3. Compatibility with the RSX family.
4. Easy to develop applications <applications sell systems).
5. A system which is efficient in disk space usage.
6. A system packaged for the end user market.
7. Support for all Micro/PDP-11 hardware and relevant options.
In meeting these goals DIGITAL plans the following actions:
1. A single installation "card" which
contains
instructions
on
installing the system.
2. A redesigned stand-alone system <single floppy subset system>.
3. Standardized additional software
installation
procedures for
layered products.
4. Autoconfiguration on host aa.chine.

RSX-llM-PLUS for the Micro/PDP-11 <Continued>
To facilitate ease of use DCL will be the
only CL! supported with the base system. Additionally, the documentation will be greatly simplified. Other features will be online help facilities and named directories.
Ease of management will be accomplished by
eliminating the sysgen <as previously
outlined), simplifying the error logger, a
simplifying
the backup procedure,
autoconfiguration, and implementation of a
startup
procedure driven by an
"English-like" parameter file <similar to
V2.0 in M-PLUS>.
RSX compatibility will be accomplished by
using the RSX-llM-PLUS V2.l executive and
file control system. RMS V2.0 will also be
incorporated. DCL and utilities in the
Micro/PDP-11 will be compatible with
RSX-llM-PLUS
V2.l.
Finally, the
Micro/PDP-11 will be upward compatible with
RSX-llM V4.1.
Applications may be compiled/linked on an RSX host system, then transferred to a
Micro/PDP-11 system. Most application debugging may be performed on the host machine. There will be programming extension kits available for native development.
As previously mentioned, the Micro/PDP-11 will be packaged for the end user market. Importance is being given to presenting a packaging/documentation combination that is
attractive to the first time user. For example, the system will be shipped in a "desiqner" box. This package will have provision for OEM resale.
The minimum recommended system will include 512 KB of RAM memory, two RX50 diskette
drives, and a RD51 10 MB fixed winchester
disk. It should be noted that the system only comes with 256 KB of memory, however for many applications, such as multiuser systems, more memory is urged. Optional hardware will include a floating point processor, commercial instruction set, line printer, RL02s, RX02s, AND DZVll'S.
The system will be available in three kits: l> base system 2) advanced programming kit 3) additional software kit.
Features to be included in the base system include online help, layered lanquage
support, and TKB. Options will include
error logqinq, and report generator control
file <RPI'>. The base system documentation kit will include the previously discussed installation card, and a two volume introduction to Micro/PDP-11 RSX.
The advanced system will allow program
development in MACR0-11. This system will
also
support
privileged
program
development, file transfer, and magtape
capability. The documentation set will be
much more extensive.
Among the additional software to be available will be the following:
1. Developmental languages
2. Communications products
3. DIGITAL layered products
4. Business applications
5. Technical applications
6. Office automation
All systems will have a ninety day limited warranty, which includes telephone support. More extensive warranties will be made available.
During the Question and Answer session, the following questions were asked:
Q. Hill the Micro/PDP-11 support shared regions?
A. Yes
Q. When will F77 be available?
A. No commitments, but hopefully this fall. It is currently being field tested.
Q. How will RX02s be supported, since RX02s are not supported in 22-bit addressing on Q-Bus systems?
A. A new device driver will be available.
Q. Hill this driver one day be available for other RSX users?
A. He'll think about it.
Q. When will DECnet be supported?
A. Hopefully this fall.
Q. What tape drive is supported?

Building and Using Resident Libraries
S. Reid Madsen Weidner Communications
Provo. UT
Allan J. Bennett. Session Chairperson Clark Equipment Company
Battle Creek. MI
Reported by Marc Caffee DECUS Scribe Service
DECUS Spring '83 Symposium St. Louis. MO
The RSX taskbuilder permits three types of shared regions: shared commons, shared libraries, and dynamically allocated regions. Several types of shared libraries were discussed. as follows:
1. Resident library - a library that requires a dedicated address window in your task.
2. Cluster library
a set of
libraries mapped through one
window !this type of library can
be very slow>.
3. Supervisor
mode
library
<RSX-llM-PLUS only> - the library
mapped uses supervisor I space
while the task is mapped in D
space.
The purpose in using a library is to reduce the physical address space required for a task by putting routines used by many tasks into a common area (library>. By doing this a net gain in physical address space
is made. Using shared libraries also reduces . disk swapping, since the space requirements for tasks is less than that required by tasks which do not use shared libraries. This not only increases throughput, but can possibly forestall the
purchase of additional memory.
An example of an existing library is the FCS library. During the SYSGEN procedure you can link a number of tasks to FCSRES. Additionally, some of the layered products (e.g. FORTRAN> have the ability to build resident libraries. In addition to the above libraries the user can write his own libraries. In order to establish a library you must: define the library contents, build the library, install the library, and
finally link the task to the library.
A user built library can contain either a
MACR0-11 source file or an overlay descriptor file. MACR0-11 source files are used by specifying the source file's global entry points. If an ODL file is used,
the file contains the names of the object modules to be included in the library.
After the contents of the library have been
established, TKB is used to build the library. By using different TKB commands you can build overlaid libraries, cluster libraries. and supervisor libraries. In
building a memory resident overlay a
potential pitfall occurs in referencing
entry points. If an entry point is not
referenced in the root segment it should be
defined using the .GBLREF option.
In building cluster libraries there are several things to remember.
1. All libraries except the first must be memory-resident overlays.
2. User task vectors indirectly
resolve
all
interlibrary
references.
3. Revectored entry point symbols must not appear in the "Upstream" symbol definition file. A .GBLXCL option must appear for each symbol being revectored to a "Downstream" library.
4. All libraries must be built PIC or built for the same address.
5. Trap or asynchronous entry into a library is not allowed.
Building a supervisor mode library is similar to building other libraries.
Once a library has been built, the next step is installation. One way to do this is to use VMR to create a new bootable system image. One strategy is to install
each library in a partition which has the same name as the task. To get the size for the partition to be created look at the
memory allocation map.
You are now ready to link to the resident library which you have created. For a non-clustered and non-supervisor-mode library use either the LIBR or RESLIB TKB options. For clustered libraries use the
CLSTR keyword. Supervisor-mode libraries are specified by SUPLIB or RESSUP.
In a test to check performance three different situations were compared:
1. No libraries
2. Cluster library in which both libraries were overlaid
3. Cluster library where the first library was not overlaid
Cases 1. and 2. had essentially the same performance, while case 3 was slower by about a factor of 9.

Dear Mr. Cook:
After receiving your letter of July l. 1983 in which you attempted to console me regarding the quality of Digital's software support. I decided to take a new attitude
towards software support, SOFTWARE DISPATCH. et al. I decided to assume all was well until the first time software support disappointed me again.
Lo and behold, today's mail brought the
July SOFTWARE DISPATCH. Fearlessly I
proceeded to apply the only relevant patch
<seq. #10.3.5.24l. Overlooking the typos
(e.g.:
"falal"l, I began following
instructions to apply the patch. I was
determined not to let minor problems change
my attitude. But, what's this???? The
text says that the patch updates to version
2.5-13 but the patch file actually updates
to 2.5-14! Oh, what the heck - I'll just
try all the different permutations of
ident's and levels until it comes up
correct.
Next, I find more typo's but this time in
the patch file (e.g.: "PAPER!" in F8.PATl.
Could this mean that these patches are
never tested before release to paying
customers? Still undaunted, I attempt to
PAT, but
perish the thought
the
checksums were wrong! Then the command
line for patching references module "F5"
which has nothing to do with the fix.
Hmmmm . . . . . so much for pleasant attitudes.
