KDATE System Option—Keep Date Determination

Use the KDATE system option to specify how a keep date is determined by indicating whether JCL, if coded, overrides the default retention. It also determines how calculated keep dates from the RMF will be handled.

Note: For information on keep date determination, see the User Guide.

This system option has the following format:

KDATE=[DEF|JCL|MAX]
DEF

The default retention will override EXPDT/RETPD in the JCL. TRS will use the calculated keep date if a count field is specified in the RMF entry.

See DEF= Tape Default Retention by Data Set Name for defining DTAB entries.

JCL

EXPDT/RETPD in JCL, if coded, will override the default retention. TRS will use the calculated keep date if a count field is specified in the RMF entry.

MAX

(Default) The larger of EXPDT in JCL or the default retention will be used as the keep date.
