Support for second-generation disk drives was provided by IBM program products such as 5734-SM1 and the later 5740-SM1 (DFSORT, alias ICEMAN, also SORT). SORT is frequently executed as a stand-alone program, where it normally reads input from a file identified by DD SORTIN and writes sorted output to a file identified by DD SORTOUT .
CALL/360:BASIC was an IBM dialect of the BASIC programming language for the System/360 and later platforms. It was based on mid-1960s versions of Dartmouth BASIC but added a number of extensions. Most of these were related to file handling, which, at that time, Dartmouth lacked.
Release 9 was issued in 1981. In 1983, IBM repackaged SSP on a new computer called the IBM System/36, which was not object-code compatible with the S/34. In 1994, IBM repackaged SSP on an updated model of the S/36 called the Advanced/36. The A/36 was an IBM AS/400 which had the SSP implemented as a "virtual machine". Major releases of SSP ...
The application program interfaces of IBM's mainframe operating systems is defined as a set of assembly language "macro" instructions, that typically invoke Supervisor Call (SVC) [e.g., on z/OS] or Diagnose (DIAG) [on, e.g., z/VM] instructions to invoke operating system routines. It is possible to use operating system services from programs ...
