Determining the Subsystem Name and Type

A caller must provide a subsystem name and type on the IWMWMCON macro. To determine the subsystem name or type, a caller can use the REQASCL SYSEVENT. The REQASCL SYSEVENT provides information about an address space's classification information. The originating subsystem should issue REQASCL, and pass the information with the work request.

For information about how to use the REQASCL SYSEVENT, see z/OS MVS Programming: Authorized Assembler Services Reference SET-WTO.
