CDSVERSIONBACKUP (OCDSBACKUPDSN): Specifying the initial characters of the backup data set name for the offline control data set

Explanation: OCDSBACKUPDSN(dsname) is an optional subparameter of the CDSVERSIONBACKUP parameter specifying the initial characters of the data set name when allocating the backup data set for the OCDS. For dsname, specify the initial characters of the data set name. You can use up to 35 initial characters, including the periods (.); however, the 35 initial characters cannot end with a period. DFSMShsm appends a final qualifier of .Dnnnnnnn or .Vnnnnnnn to the backup name you choose. DFSMShsm uses the total name to allocate the backup data set for the OCDS.
