Abstract for MVS Programming: Assembler Services Reference, Volume 2 (IARR2V-XCTLX)

Purpose of this information

This information describes some of the macros (or macro instructions) that the system provides. The macros described in this information are available to any assembler language program.

Programmers who code in assembler language can use these macros to invoke the system services that they need. This information includes the details, such as the function, syntax, and parameters, that are needed to code the macros.

Who should use this information

This information is for any programmer who is coding an assembler language program.

How to use this information

This information is one of the set of programming information for MVS™. This set describes how to write programs in assembler language or high-level languages, such as C, FORTRAN, and COBOL.
