Deleting expired data sets

For non-SMS-managed data sets, DFSMShsm deletes those data sets that have passed their expiration date. For non-VSAM data sets this would be the expiration date in the data sets' VTOC entries and for VSAM data sets this would be the expiration date in the data sets' catalog entries. For these data sets, the EXPIREDDATASETS parameter of the SETSYS command controls whether the data sets are deleted.
