.Figure 39. Job Control Cards Required for Execution of the Sample frogram
~~,g~~Y1iQ'!! (a) the tape IPL deck up to and includ-
The sample programs have been designed for
execution on systems with the following I/O
devices:
~ For the master Frogram:
• An IEM 2501 Card Reader
• An IEM 1403 or 2203 Printer
• The Binary Synchronous Communica-
tions Adapter (Feature No. 2074)
b) For the slave program:
• An IBM 2520 Card Punch
• An IEM 1403 or 2203 Printer
• The Einary Synchronous Communica-
tions Adapter (Feature No. 2074).
If the user's I/O configuration differs
from that shown above, the DTFSR cards in
the source sample program (s) (see Figure
38) must be changed.
It is assumed that 16,384 bytes of main
storage are available for execution; if the
user's Model 20 has a different storage
capacity, the a~propriate job-control card
(statement 4 in Figure 39) must be changed.
OPERATING PROCEDURES
!22~1!!121Y
The following steps must be taken to
assemble the master or the slave source
program and obtain the object program in
the required form~
1. Place into the hopper of the loading
unit:
ing the END card,
(b) an ASSGN card for SYS1HS (prepared
by the user)
ec) an ASSGN card for SYSRDR (prepared
by the user) if SYSBtB is not the
IBM 2501 Card Reader
(d) the end-of-file card (/* in columns
and 2).
2. ~ount the system tape on the drive
assigned to SYSRES and press the Load-
Rewind key and the Start key of the
drive.
3. ~ount work tapes on the drives assigned
to 5YSOOO and SYS001. Press the Load-
Rewind keys and the start keys of these
drives.
4. If the object program is to be put onto
tape in card-image format for sutse-
quent execution under control of the
!E2~-resident system, perform the addi-
tional steps (a) and (1:;) l::elcw. Other-
wise, (if output in cards is required)
continue with steF 5.
a) Change the ASSGN SYSCf'I card
(statement 7 of Figure 38).
b) Mount an output tape on the drive
assigned to SYSCfT and press the
Load-Rewind key and the Start key
of the drive.
5. Place the job-control cards (statements
1 to 9 in Figure 38) into the hopper of
the card reader assigned to SYSRDR.
fress the start key of this device.
6. Place the sample source program into
the hOfper of the device assigned to
