This pUblication contains information on the emula-
tion of 1401, 1440, and 1460 object programs under the
control of the Disk Operating System. Compatibility
Support/30 and Compatibility Support/40 allow emulation
of these programs on the IBM System/360 Models 30 and
40, respectively. Compatibility Support/30 comprises
the IBM 1401/1440/1460 Emulator Program, Number 360N-
EU-484, and applicable Compatibility Features for the
Model 30. Compatibility Support/40 comprises the 1401/
1440/1460 Emulator Program, Number 360-EU-485, and the
applicable Compatibility Features for the Model 40. In
addition, the 1401, 1440, and 1460 object programs can
be run on the IBM System/360 Model 25 using the
1401/1440/1460 Emulator Program for Compatibility
Support/30 in conjunction with applicable Compatibility
Features for the Model 25.
General information concerning machine requirements,
program generation, simulation techniques, data for-
mats, control cards, and programming considerations is
included, as are detailed explanations of Operator
Service Functions, operating procedures, console mes-
sages, and special instructions added by the Compati-
bility Features for the Models 30 and 40.
The 1400 Emulator Programs under DOS allow the user
to run 1401/1440/1460 programs, with little or no
reprogramming, under the Disk Operating System in
conjunction with the Compatibility Features. This
allows 1400 programs to be run in a stacked job
environment, mixed with System/360 jobs.
