Return codes from user macros

When using the user macros, DFSMShsm sets a return code in register 15 that indicates the result of processing the request. In most cases, the return codes correspond to the message number that DFSMShsm issues to provide an explanation when the request fails. If there is a reason code associated with the failure, it is returned in register 0.

Table 1 lists the return codes that are placed in register 15 upon completion of the invocation of the macro.
