http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/DGT2I2A0/B.0? The keywords you would be interested are INDEXED--The data component has an index; it is key-sequenced aka KSDS. LINEAR--The cluster is a linear data set aka LDS NONINDEXED--The data component has no index; it is entry-sequenced aka ESDS. NUMBERED--The cluster is a relative record data set aka RRDS.
