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 ...
Beginning of Program: Indicates the start of a new program to be assembled separately from previous programs in the same card deck. EQU: Equivalence: Equates a symbol to an absolute, regional, or symbolic value. SYN: Synonym: Equates a symbol to an absolute drum address. The address is marked unavailable for assignment
IBM's original OS/360 sort/merge program, 360S-SM-023, program name IERRCO00 (alias SORT), supported only IBM's first-generation direct-access storage devices (DASD) [d] and tapes (2400). 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).

The output is binary data in the twelve card rows 12, 11, and 0–9. Each row contains two 36-bit words in columns 1-36 and 37-72, indicated as left (L) and right (R) respectively. Data is conventionally numbered by row and position, for example, columns 1 to 36 of row 9 are designated 9L, columns 37 to 72 of the same row are 9R.
