The CICSPlex SM command-level interface

This section describes the command format, argument values, and value data areas of the CICSPlex® SM command-level interface.

z/OS restrictions

A number of general restrictions apply to all CICSPlex SM API commands.
  • The program must be in primary addressing mode when invoking any CICSPlex SM service. The primary address space must be the home address space. All parameters passed to CICSPlex SM must reside in the primary address space.
  • CICSPlex SM does not always preserve access registers across commands. If your program uses access registers, it should save them before invoking a CICSPlex SM service, and restore them before reusing them.

Language considerations

All of the language considerations that apply to the various environments (CICS®, z/OS® batch, TSO, and NetView) also apply to CICSPlex SM programs written to run in those environments.
