The LMMDEL service removes members matching the specified pattern from an ISPF library or MVS™ partitioned data set. All directory information associated with the member is deleted. The LMINIT and LMOPEN services must be completed before you use the LMMDEL service. The LMINIT must be done with either the ENQ(SHRW) or ENQ(EXCLU) option, and the LMOPEN must have been done for OUTPUT. An LMINIT with ENQ(EXCLU) is required when MEMBER(*) is specified.
