DATASET specifies a data set dump operation, using filtering. See DFSMSdss filtering—choosing the data sets you want processed for an explanation of the filtering process used. Unless the ALLDATA or ALLEXCP keyword is specified, only used tracks are dumped for sequential and partitioned data sets and for data sets with no defined data set organization (for example, JES2/JES3 data sets). If the free space map in the VTOC is invalid, all tracks are dumped.
