IBM System/360 20 User Manual

• an IBM 2560 MFCM
• an IBM 1403 Printer
• an IEM 2415 Magnetic Tape Unit, any
model, (9-track drives with unit numbers
starting at 80) •
If the user's Model 20 system has a dif-
ferent I/O configuration or different tape
unit numbers, the ASSGN cards in the sets
of job control cards and/or the REP cards
supplied with the tape IPL must be changed.
If the user's Model 20 system includes
two tape.drives only, the last two sample
jots (sorting of records and printing of
sorted records) cannot be performed.
The following steps must be taken to
perform the five (stacked) sample jobs:
1. Mount the system tape (containing the
utility programs and, if the Sort job
is to be performed, the Sort/Merge pro-
gram) on the tape drive assigned to
SYSRES (see ASSGN card in group X90).
Press the Load-Rewind key and the Start
key of the device.
2. Mount a blank tape on the tape drive
assigned to SYSOOO in card group X90,
and press the Load-Rewind key and the
Start key of the drive.
3. Remove the ASSGN cards for SYSRES and
SYSRDR from card group X90 and place
them in the IPL deck, in front of the
REP cards (if use~ and the end-of-file
card. Place this deck into the hopper
of the loading unit (2560 primary feed
in the example).
4. Remove the CONFG cards from card groups
X90, V90, and W90. (These cards are
used in a card-resident system run.)
5. Place card groups X90-V91 and W90-W91,
in the sequence shown in the above
list, into the hopper of SYSRDR (2560
primary feed in the example).
6. If the Sort job is to be performed,
place card groups S90-W93 into the
hopper of SYSRDR, behind group W91.
7. Place card group V92 (data cards) and
an end-of-file card into the hopper
of SYSIPT (2560 secondary feed in the
example) •
8. Fress the Start key of the card device
used.
9. Install forms in the printer, and press
the Reset key and the start key of the
device.
10. Set the Register-Data/Address switches
on the CFU console to an even main
storage address between hexadecimal
009C and the end-of-storage address
minus hexadecimal 0052.
11. Set the Mode switch on the CEU console
to PROCESS.
12. Press the Load key on the CEU console.
A volume label is written on the tape
mounted on SYSOOO. Then, the data is read
from the cards and written onto the tape.
In the third jot, the data is read from the
tape and listed on the printer.
If the ~odel 20 system has two tape
drives, the sample run is completed. If
the system has four or six tape drives, a
PAUSE card is read after the third job, and
the code OE40 is displayed. Perform the
following steps:
1. Mount an unlabeled output tape on the
drive assigned to SYSOOO in card group
S90 (job control cards for Sort job).
2. Mount an unlabeled work tape on the
drive assigned to SYSC05 in card group
S90.
3. Press the Load-Rewind keys and the
start keys of the drives.
4. Fress the start key on the CEU console.
After halts 1COA and 1C41 are displayed
(warning messages), press the Start key
on the cpu console.
The data is read from the labeled tape,
sorted by the contents of column 27, and
written onto the unlateled output tape.
!hen, the sorted records are read from the
tape and listed on the printer. Code 01DO
is displayed, completing the sample-program
run.
