DALEXPDT specifies the date when the data set can be deleted or overwritten by another data set. This key is mutually exclusive with the long form of the expiration date (DALEXPDL), the retention period (DALRETPD), and SYSOUT (DALSYSOU) keys. IBM® recommends that you use the DALEXPDL rather than DALEXPDT to specify an expiration date.
When you code DALEXPDT, # must be one, LEN must be five, and PARM contains– five digits a two-digit year value and a three-digit day value (yyddd).
