This topic contains general-use Programming Interface and Associated Guidance Information.

This topic lists the variables you can use for automatic class selection (ACS) routines during DFSMSdss copy, restore, and CONVERTV operations, and describes the processing of ACS routines. This information is provided for guidance purposes only. It is not associated with any interface provided by DFSMSdss.

Messages generated by ACS routines are not printed by DFSMSdss unless the ACS routine returns a non-zero return code.
