The FLM00CVE REXX Exec can be invoked as a regular MVS™ Exec, but it is designed to be invoked as an SCLM change code verification user exit. If FLM00CVE is invoked as a user exit, the Information Management-specific arguments are passed by the SCLM option list defined in the FLMCNTRL macro. The SCLM-specific arguments are appended to the Information Management arguments.
