Register usage for return codes

Use the parameters of the macro to specify an explicit value or an address of a data field. They can be specified in any order. When the address of a data field is specified, registers 2 through 12 can be used. For example, SNAPDCB=(3) or a symbol, SNAPDCB=DCBAREA, can be used.

The application program must ensure that register 13 contains the address of a standard 18-word save area. The following return codes are placed in register 15 upon completion of the invocation:

Return code: Description
0: Function is successful
100: DFSMShsm is not running or the request could not be communicated to DFSMShsm
400: Invalid request ID
401: Attempt to free a MWE for an incomplete function (applies to ARCFMWE only)
402: Data set locate failure (applies to ARCHRCAL and ARCHMIG only)
403: Data set name specified was * or blank
404: The date specified with ARCHRCOV has format yyddd, but the system date is later than 1999.
806: Link error
Any other nonzero: Function fails
