From the "z/OS v1r6.0 JCL Reference Manual":

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2B650/12.19?DT=20040712170508

CATLG Indicates that, if the step terminates normally, the system is to place an entry pointing to the data set in the system or user catalog.

KEEP Indicates that the data set is to be kept on the volume if this step terminates normally. Without SMS, only KEEP is valid for VSAM data sets. VSAM data sets should not be passed, cataloged, uncataloged, or deleted. With SMS, all dispositions are valid for VSAM data sets; however, UNCATLG is ignored. For new SMS-managed data sets, KEEP implies CATLG.
