Subparameter definition

z/OS MVS JCL Reference

Specifies the retention period, in days, for the data set. The nnnn is one through five decimal digits ( 0-93000).
Note: At releases z/OS 1.10 through z/OS 1.12, the system will accept RETPD values up to 93000, however, when the value coded is above 9999, then 9999 will be used.

The system adds nnnn to the current date to produce an expiration date. For SMS data sets, the system adds nnnn to the data set creation date to produce an expiration date. The calculated expiration date uses 365-day years and 366-day leap years. However, if the produced expiration date exceeds December 31, 2155, then the expiration date will be set to December 31, 2155.

Note: If you code RETPD and the calculated expiration date is December 31, 1999, the expiration date is set to January 1, 2000.
