IBM System/360 20 User Manual

• place the deck of macro defini-
tions produced by the
Distribution-Package Retrieval
program (beginning with a FRIOR
card and a CATAL card, containing
interpersed PRIOR and CATAL cards,
and terminated by a 1/ END control
card) in the hopper of the device,
behind the EXEC card.
b) If SYSIPT refers to a card reading
device other than that assigned to
SYSRDR:
•
place the separate control-card
deck produced by the Distribution-
Package Retrieval program in the
hopper of SYSRDR, behind the EXEC
card;
• place the deck of macro defini-
tions, terminated by the // END
card, in the hopper of SYSIPT.
(The interpersed PRIOR and CATAL
cards in the deck are ignored by
the MMADl'I program) •
c) If SYSIPl' :cefers to a tape drive,
place the separate control-card deck
produced by the Distribution-Package
Retrieval program in the hopper of
SYSRDR. The input tape en which the
macro defini tions are stor ed is
still mounted on SYSIPT from the
LDSYS or previous MMAINT run (s) ;
5. If SYSOOO refers to the same tape drive
as in the preceding LDSYS or MMAINT
run, the work tape is still mounted and
positioned.
If a different drive is used as SYSOOO,
mount a work tape on the drive; fress
the Load-Rewind key and the start key
of the drive.
6. Mount an output tape on the drive
assigned to SYSOPT; press the Load-
Rewind key and the start key of the
dri ve.
7. If the printer (SYSLST) is used to list
the macro definitions, press the Reset
key and the start key of the printer.
8. Press the Start keys of any required
I/O units that are not yet ready.
9. Press the Load key on the CPU console.
After the IPL procedure, the Mr.AINT pro-
gram is read into storage and executed. A
number of programmed halts may occur during
processing. The halt codes displayed and
the appropriate restart procedures are
described in the section g~Qg££~~g~-H~l!
~~~~l~E-Eng_]~~!E£!_I£g~gQre§.
On completion of the f~AINT run, the
system halts, and code OD10 is displayed in
the E-S-T-R registers on the CPU console.
The system tape, which now includes a
macro library, is on the drive assigned to
SYSOPT.
If more macro definitions (i.e., those
for the 1419/1259 and/or for the BSCA) are
tc be included, additional MMAINT runs
should be executed. Repeat steps 1 through
9 described above, but note that SYSOPT
from the previous run becomes SYSRES in the
next run: SYSRES from the previous run can
be assigned to SYSOPT in the next run.
Figure 13 is an example of the tape
handling to be carried out when a system
tape is being created for a system with
four tape drives, and when all three files
of IBr.-supplied macro definitions are
required. If the 14-19/1259 macro defini-
tions, but not those for BSCA IOCS are to
be included in the macro library, the
second MMAINT run represents the tape-drive
handling for inclusion of the 1419/1259
macro definitions.
