Subsequently modifying the expiration date of a backup volume

MAREN allows you to modify the expiration date of a backup volume at a later stage.

Example

All volumes of a save run are to be protected against overwriting for 31 days as of today. This involves changing the expiration date:

//MODIFY-TAPE-SET-ATTRIBUTES - 
//   SELECT=*BY-ATTRIBUTES(FILE-NAME=FDDRL.D.WORK01,VERSION=*ALL), - 
//   PROTECTION=*PARAMETERS(EXPIRATION-DATE=31)
