Introduction
This publication provides yoq with the
detailed procedures and operating instructions required to
•
prepare operable disk-resident and cardresident systems from IBM-supplied
initial distribution and replacement
distribution packages;
•
update your operable systems with IBMsupplied modification (maintenanc~
packages; and
•
generate a tailored Monitor from IBMsupplied Monitor Generation Macro
Definitions.
When you initially order the programming
support for the IBM System/360 Model 20
Disk Programming System, IBM supplies you
with the latest versions of all IBMdeveloped programs and macro definitions
available for the Model 20 DPS.
Initial
distribution is sent to you on a disk pack
or reel of magnetic tape supplied by you.
The procedures you must follow to prepare
an operable disk-resident system (or
systems) and ~ptionally) a card-resident
system are described in the section ~~ystem
system is necessary. If it is not necessary to prepare a new system, you must use
the procedur.8;s described in the section
System Maint'enance.
Replacem~nt and modification packages
are also distributed on a disk pack or a
magnetic tape reel supplied by you.
The IBM-supplied distribution and
replacement packages contain a standard
Monitor.
Th~s Monitot corresponds to a
generated Monitor defined by the default
specifications described in the section
Monitor Gener,ation. If the requirements 0,[
your installation differ in any way from
the features supported by this standard
Monitor, you should generate a tailored
disk-resi.den:t: Monitor. Also, if you want
to prepare a card-resident system, you must
generate a Monitor of the type CDRES to
obtain the card-resident control programs
~PL, Monitor, Job Control).
The specifications and operating procedures for generating a Monitor are described in the section Monitor Generation.
Pr'§'12~~ation.
IvlAXIf1UM SYSTEM CONFIGURATION
IBM is constantly making improvements or
adding new features to the components
(programs and macro definitions) of the
Model 20 DPS. Whenever any changes to the
DPS have been developed by IBM, an
announcement is made. If you want to
update your existing system with the latest
moflifications and improvements, you must
order the new release.
When the changes that have been made to
the system are extensive, IBM distributes a
complete system. Such a distribution is
called a replacement distribution and
requires the preparation of a completely
new system. The procedures you must follow
for preparing operable disk-resident and
card-resident systems from a replacement
distribution package are the same as for
initial distribution. They are described
in the section System Preparation.
When only minor changes have been made
to the system, replacement of the entire
system would be impracticable. Therefore"
the changes are distributed in modification
packages which are designed so that you can
incorporate all or some of the modified
components into your existing systems. The
documentation accompanying a new release
will indicate whether preparation of a new

System Preparation
When you order a replacement release or
when you initially order programming support for the Model 20 DPS, you receive a
full system comprised of all IBM-supplied
programs and macro definitions plus a file
containing sample programs. These DPS
components are listed in Figure 1. Depending on whether or not your system configuration includes magnetic tape drives, IBM
distributes this programming material to
you on a reel of magnetic tape or a disk
pack supplied by you.
If distribution is on tape, it must
first be copied onto a disk pack before it
can be used. This and the punching out of
the card-resi.dent par.t of the disk IPL are
accomplished by executing the first program
on the distribution tape. If distribution
is on disk, a card deck containing the
bard-resident portion of the disk IPL program is sent along with the distribution
disk pack.

Punch Sample ProgE~ms. If you want the
set of IBM-supplied sample programs for
operator training or for testing your
new system after preparation is complete, punch the sample programs from
the sample program file on disk into
cards.
3.
Prepare Card-Resident System. If you
want to use the card-resident control
programs (IPL, Monitor, and Job
Control), generate a card-resident
Monitor. You can also punch out IBMsupplied programs which you may wish to
execute under control of the cardresident system.
4.
Prepare a Minimum System.
If you want
a minimum system containing (l minimum
of IBM-supplied programs and including
your own programs and macro
definitions, do the following:
The distribution disk pack supplied by IBM
or prepared by executing the first program
on the distribution tape contains two
files:
•
•
The system file, which contains all
disk-resident DPS programs and macro
definitions in the form of an operat.ional system.
If distribution is on disk,
copy it onto another disk pack or punch
it into cards and save the disk pack or
cards as backup. If distribution is on
tape, copy it onto disk and save the
distribution tape as backup.

GENERAL PROCEDURE FOR SYSTEM PREPARATION
The distribution disk pack and the IPL
cards together comprise an operable diskresiden;: system. Therefore, all you need
in order to begin system operation is to
prepare a backup copy of the system.
However, in addition, you may want to punch
out the sample programs and prepare a cardresident system, a minimum system, or a
modified system.
~he recommended procedure for use in
preparing the system that meets the
requirements of your individual installation is:
8
a. Generate a minimum-sized Monitor
tailored to your programming
requirements.
I
b. Punch out the required IBM-supplied
programs from the distribution disk
pack.
c. Load the IBM-supplied programs, the
generated Monitor, plus your own
programs onto the minimum system,
disk pack.
5.
Prepare Modified System.
If you want
to use a full disk-resident system, you
can modify the IBM-supplied distribution pack by doing the following:
a. Generate a tailored disk-resident
Monitor and replace the standard
Monitor by the generated Monitor on
the distribution pack.
b. Delete the IBM-supplied programs and
macro definitions you do not require
from the core-image and macro
libraries and add your own programs
and macro definitions to the system.
c. Redefine the limits of the libraries
and directories of your modified
system.
d. Make a copy of your modified system
on disk or tape or punch it into
cards to use as backup.
The operating procedures to follow and
the jobs to perform upon receiving an initial distribution or replacement distribution package are shown in Charts AO

System Maintenance
When you order a new release in which only
minor modifications or improvements have
been made to the components of the IBMsupplied system, you will receive a
modification (maintenance) package. If the
configuration of your Model 20 installation
includes magnetic tape drives, the modification package is distributed on a reel
of magnetic tape. This tape is either
supplied by you, or, if the modifica~ions
can be copied onto a Distribution Tape Reel
(length = 200 feet), the modification package is distributed on a DTR.
If your
installation only includes disk drives, the
modification package is distributed on a
disk pack supplied by you.
With the distribution tape, a bootstrap
card is distributed, and with a distribution disk pack, the card-resident portion
of the disk IPL is distributed.
If the modification package is on tape,
it must first be copied onto a disk pack by
executing the first program on the modification tape using the bootstrap card.
A modification package distributed on
disk (or obtained by copying tape onto
disk) consists of the following:
•
A minimum system file including
1.
2.
3.
A Label-Information Area (LIA).
System control programs (disk IPL,
standard Monitor) •
Core-image library containing the
disk Job Control program and
a.
b.
c.
d.
e.
22
Disk-to-Card Utility program
(DSKCAR) for punching out the
IBM-supplied control card file
and any new or changed sample
programs,
Disk-to-Printer Utility program
(DSKPRT) for listing the control
card file on the printer,
Physical and Logical Unit Tables
Service program (PSERV) for
including assignments for any
attached tape drives in the
standard Monitor,
Initialize Disk Utility program
(INTDSK) for printing VTOC and
initializing the work pack or
backup pack,
Core-Image and/or Macro Service
programs (CSERV and MSERV) for
obtaining the new program phases
and/or macro definitions from
the core-image and macro libraries on the modification pack.
After these are obtained in
cards or on a work tape or disk,
they can be used as input to the
f.
4.
CMAINT and MMAINT programs.
(The CMAINT and MMAINT must be
on your system pack to be updated.)
Any new or modified program
phases.
Macro library containing any new or
changed macro definitions.
•
A file containing any new or modified
sample pr.ograms.
•
The control-card file containing all job
control and program-control statements
for the jobs required to update your
disk-resident systems with the new and
changed pr.ogram phases and macro definitions. This file has been prepared to
be used in a job stream.
If you receive the modification package
on disk, the only cards you have to prepare
are the control cards for the Disk-to-Card
Utility program (JOB DSKCAR) to punch out
the control-card file.
When the modificat~on package is distr.ibuted on tape, you
will also have to prepare control cards for
(1) copying this tape onto a disk pack (JOB
RESTOR), (2) punching out the card-resident
part of the disk IPL (JOB PUNCH), and (3)
aSSigning one or more attached tape drives
(~OB PSERV)
i.f you are using the IBMsupplied standard r-~oni tor. At least one
tape drive must be aSSigned if you use a
tape as ~ntermediate storage media.
As soon as you have obtained the
control-card file in cards, remove the
program-contr:ol cards that will catalog or
include any program phases or macro definitions you do not need in order to update
your system.
During execution of the CSERV and MSERV
j.obs, halt OB40 (PAUSE) will occur. This
is requir.ed s,ince some system programs
(such as CMAINT and the Monitor) must be
cataloged i~ a predetermined sequence.
Therefore, do not change the sequence of
the job contr:ol cards; remove only programcontrol cards.
According to the configuration of your
Model 20 installation you must complete
certain ASSGN cards and prepare your system
for the jobs to be performed.
Details on
how to complete these cards and the
operating procedures you should follow to
update your systems are shown in the following charts (Charts F through J) •
A skeleton of the cards that will be

IBM Supplied Control-Card Fil6
This file contains all job-control and program-contral cards,
required for the DSKPRTand DSKCAR jobs and any CSERV,
MSERV, CMAINT, and MMAINT jobs to update your current
system. The comment portion of the listed control cards contains information to aid you in preparing and executing the
necessary jobs.
You must always have as many CMAI NT jobs as you have
CSERV jobs. Each CSERV job will punch out or write on tape
or disk the same number of program phases as the following CMAINT
job will catalog into the core-image library of your current
system. Likewise, each MSERV job will punch or write out the
same number of macro definitions as the following MMAINT
job will include in the macro library of your current system.
Therefor"for each I I PUNCH phasename card you remove
from the CSERV job, you must remove the corresponding
II CATAL phasename card from the CMAINT job; and for
each II PUNCH macroname card you remove from an MSERV
job, you must remove the corresponding II INCLD macroname

Required Coding
Figure 8 shows the coding required to generate the above Monitor. The numbered
comments below refer to the circled references in the right margin of the coding
sheets.
1•
Refer to the pertinent sections of the
SRL publication IB~_~~tem/360 Model
~QL_Qi~~_Rrogramming System, Control
~nd §ervi~~~rogE~~~, Form C24-9006.
Permanent assignments in existing Monitor:
2.
SYSIPT
SYSOPT
SYSLST
SYSLOG
Since the output is written into the
relocatable area only, the operand
NODECK must be added to the AOPTN
statement.
3.
Since a disk-resident Monitor is to be
generated, the macro instruction CDIPL
is crossed out.
4.
A disk-resident Monitor is to be generated with no transient phases and with
no inquiry facilities. Since the
default specification TYPE=DKRES corresponds to this type of Monitor, the
operand is crossed out and the default
specification is automatically assumed.
5.
The Monitor to be generated does not
support inquiry facilities, hence these
three operands are ignored by the
Assembler and are crossed out.
6.
The printer-keyboard is to be employed
as I/O device in this system. Since
this requirement is not identical with
the default specification, the operand
is specified.
7.
Since BSCA is not required, this operand is crossed out and the default
specification is automatically assumed.
8.
The default specifications are identical with the required specifications.
Therefore the operands are crossed out
and the default specifications are
automatically assumed.
9.
The operand TAPES=2 is specified
because the default specification differs from the required specification.

10. Tapes are to be supported and tape
error statistics are required. Since
the default specification is TES=YES,
the operand is cr9ssed out.
11. The operand LUBSIZE=10 is specified
since the desired specification differs
from the default specification.
12. These assignments for SYSIPT and SYSOPT
are made because the required assignments differ from the default specifiMonitol Generation
51
statement is required since only one
additional Monitor phase is generated.
cations. Assignments for SYSLST and
SYSLOG are not required because the
printer attached is automatically
assigned.
Output:
13. Both ASSGN macro instructions are
crossed out because the default specifications are identical with the
required assignments.
The result of the assembly and CMAINT runs
is a disk-resident system including the
following new phases
•
14. SYS002 and SYS003 are assigned the two
drives of the 2415 Tape Unit with the
addresses 80 and 81.

Required Coding
Figure 9 shows the coding required to generate the above Monitor. The numbered
comments below refer to the circled references in the right margin of the coding
sheets.
1.
Refer to the pertinent sections of the
SRL publication IBM System/360 Model 20
Qisk_E~Qg~~~ming_~ystem, Control and
Service Programs, Form C24-9006.
2.
Since no cross-reference list is
desired and the output is to be punched
into cards, the Assembler AOPTN statements with the operands NODECK and
CROSSREF are crossed out.
3.
Since a disk-resident Monitor is to be
generated, the Macro instruction CDIPL
is not required and is therefore
crossed out.
4.
Since a disk-resident Monitor with
transient routines is to be generated,
the operand TYPE=TRANS is specified.
5.
Inquiry facilities cannot be supported
by this Monitor. For this reason the
operands INQIPT, INQOPT, and INQMSG are
ignored by the Assembler and are therefore crossed out.
6.
Since the printer-keyboard is not to be
supported, and since the default specification for this operand is NO, the
operand is crossed out.
7.
Since BSCA routines are not required,
this operand is crossed out and the
default specification is automatically
assumed.
8.
The default specification of each of
these five operands is identical with
the required specification. Therefore
all five operands are crossed out and
the default specifications are automatically assumed.
9.
The operands RWC=YES and QUEUES=NO must
be specified to override the default
specifications.
Disk-resident Monitor

•
for main-storage capacity of 12,288
bytes
•
for two disk drives
•
for six tape drives
•

•
without BSCA routines
•
with RWC feature
•
without queuing of disk and tape 1/0
requests

10. The ASSGN macro instructions for SYSIPT
and SYSOPT are specified since their
required assignments are not identical
with the default specifications.
Output:
11. These four ASSGN macro instructions are
crossed out since their default specifications are identical with the
required assignments.
The output of the assembly run is a card
deck consisting of the following phases
•
12. SYS002 through SYS007 must be assigned
as shown in order to insert the physical addresses for magnetic tape drives
into the six physical unit blocks
(PUBs) which will be reserved in the
Monitor by the default specification
TAPES=6.
Permanent Link Data Area (Communication
Region, LUBs, and PUDs)
Physical IOCS (Scheduler, Disk Error
Recovery routine, and Disk and Tape
Start I/O routines)
Core-resident Fetch routine
Transient Area
13. The remaining ASSGN macro instructions
are superfluous since no further
assignments are required.

14. Since the output of the assembly run is
to be a card deck, these control statements are automatically generated and
included in the output deck. Therefore
they are crossed out on the coding
sheet. However, a // END statement
must be placed behind the Monitor deck
before it is used as input to the
