The framework for a macro library is
created during the LDSYS run.
Macro
definitions can, however, only be added to,
or deleted from, the library cy means of
the MMAINT (Macro Maintenance) program.
Therefore, if the system is to include a
macro library, the MMAINT program must be
included on the tape at retrieval
time~
This section describes the procedure fer
using the MMAINT program to include IBM-
supplied macros in the licrary.
It is also
applicable when these macros are to be
updated from modifications supplied by IBM.
Further notes on the macro library,
together with details of the procedures for
deleting unwanted items and for adding
user-written macro definitions will be
found in the section

The macro definitions supplied by IBM
are contained on the distribution tape in
three files:
1.
TPS Input/Output and Basic Monitor
macro definitions
2.
TPS Input/Output macro definitions
for the Binary Synchronous Communi-
cations Adapter
3.
TPS Input/Output macro definitions
for the IBM 1419 and 1259 Magnetic
Character Readers.
Any or all of these files (depending on
the user's requirements) are retrieved from
the distribution tape during the retrieval
run.
These files are now on the tape drive
assigned to SYSIPT in the LDSYS run.
Each
file is preceded by a tape mark.
On com-
pletion of the LDSYS run, the tape is posi-
tioned just before the first tape mark.
If only the Input/Output and Basic Mon-
itor macro definitions are to be used, one
MMAINT run will be sufficient.
If the sys-
tem also includes the BSCA and/or a Magnet-
ic Character Reader (1419 or 1259), two or
three additional MMAINT runs will be
required to insert the macro definitions
for these devices into the licrary.
The steps to be performed for each addi-
tional run follow the same pattern, as
described below.
1.
Remove the file-protection ring from
the system tape
(on the drive assigned
to SYSOPT in the previous run), remount
the tape on the drive, and press the
Load-Rewind key and the start key of
the drive.
2.
Place in the hopper of the loading
uni t:
a) the tape IPL deck up to and includ-
ing the END card;
b) an ASSGN card assigning the drive on
which the system tape is mounted to
SYSRES (this is the drive that was
assigned to SYSCfT in the LDSYS or
previous MMAINT run (s»
;
c) an ASSGN card for SYSRDB (if a
device other than the assigned one
is to be used) ;
d) the (corrected) REP cards (unless
the correct assignments were
inserted in the tape Basic Monitor
by means of the LDSYS program)
e) the end-of-file card
(/*
in
cols. 1-2).
3.
Place cards containing the following
job control statements in the hopper of
SYSRDR:
// JOE
.MMAINT
/ / DATE
/ / ASSGN SYSIPT
// FILES SYSIPT,1
// ASSGN SYSOPT
(same device as
during LDSYS or
previous MMAINT
run (s)
(used only if
SYSIPT refers to
a tape drive)
(tape d ri vel
// ASSGN SYSOOO
(tape drive:
required unless
assignment was
made during
LDSYS)
/ / A SSGN SYSLST, UA
(required if the
macro definitions
are not to be
listed)
// CONFG
Required if more
/ / EXEC
than 8K bytes of
main storage are
available.
(Allows faster
processing) •
4.
a)
If SYSIPT refers to the same card
reading device as SYSRDR:
• remove the separate control-card
deck (PRICR and CATAL cards)
from
the output deck produced by the
Distribution-Package Retrieval
program;
