OS/MVS and DOS/VSE Group

The OS/MVS and DOS/VSE group consists of macros also provided by the OS/MVS and DOS/VSE operating systems. CMS supports these macros to make it easier to run CMS programs originally developed for OS/MVS or DOS/VSE.

See the z/VM: CMS Application Development Guide for Assembler for more information on the OS/MVS and DOS/VSE group.

Note: CMS macros, control blocks, and functions that are not part of the CMS defined programming interface are considered CMS internals. These macros, control blocks, and functions should not be used by programs other than CMS.
