IBM System/360 20 User Manual

The following steps must be taken to
build a system tape from programs obtained
as output from the Distribution-Package Re-
trieval program.
1. Place the card IPL deck, an ASSGN card
for SYSRDR and the card Basic Monitor
deck in the hopper of the loading unit.
(The tape unit numbers in the REP cards
of the Easic Monitor deck may have to
be changed to the numbers of the drives
act ually attached.)
2. Place in the hopper of SYSRDR:
a) phase 00, 01 and 02 of the card Job
Control program deck
b) cards containing the following job
control statements:
// JOE
// DATE
LDSYS
// ASSGN SYSIPT
// ASSGN SYSOPT
// ASSGN SYSOOO
// EXEC
(if not 2501)
(tape drive)
(if tape charac-
teristics have
to be added to
the standard
assignment)
c) phase 03 of the card Job Control
prog ra m deck
d) the Load System Tape program deck
3. If input for the LDSYS run is in
punched cards, the tape-resideRt Con-
trol programs (sequence num1:er 15) must
also have been punched into cards dur-
ing execution of the Distri1:ution-
Package Retrieval program. Follow
either procedure (a) or procedure (b)
below.
If input for the LDSYS run is from
magnetic tape, follow procedure (c).
(a) If SYSIPT refers to the same
card-reading device as SYSRDR:
i. Insert into the deck contain-
ing the tape-resident Control
programs any new or replace-
ment ASSGN and/or CONFG cards
required to change the stan-
dard entries in the taFe
Basic Monitor program to the
actual configuration of the
Model 20 system. (these
cards must be placed immedi-
ately after the Basic Monitol
program -- see Figure 5).
ii. Place into the hopper of the
card-reading device:
• the deck containing the
tape-resident Control
programs
• the deck containing the
user-selected programs
(sequ en ce num 1:ers 15 to 29)
to be included on the sys-
tem tape, in the same order
as they were punched by the
Distribution Package Re-
trieval program
• a // END control card (to
be prepared by the user).
(b) If SYSIPT refers to a card-
reading device other than that
assigned to SYSRrR:
i. Place into the hopper of
S YSRDB:
•
the // ~CNTE card from the
tape-resident Control pro-
gram deck (to be prepared
by the user)
• any ASSGN and/or CONFG
cards required either to
change the standard entries
in the tape Easic Monitor
program to the actual con-
figuration of the Model 20
system or to insert tape-
drive assignments
• a // END control card (to
be prepared by the user).
ii. Place into the hopper of
SYSIPT:
• the remainder of the deck
containing the tape-
resident Control programs
• the deck containin9 the
user-selected programs
(sequence numbers 16 to 30)
to be included on the sys-
tem tape, in the same order
as they were punched by the
Distribution Package Re-
trieval program
• a // END control card (to
be prepared 1:y the user).
