File No. S360-35 Form C27-6940-2 DOS Systems Reference Library IBM System/360 Disk Operating System 1401/1440/1460 Emulator Programs Compatibility Support/30 Compatibility Support/40 Program Number for CS/30: 360N-EU-484 I Program Number for CS/40: 360N-EU-485 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.
