Sure you can do it. It's the EXPIRATION DATE field. To implement this field, you must use the SET VOL/RETENTION command. This keeps the EXPIRATION DATE updated within a specified window (default: 1 week). The window is to keep system overhead down. Updateing this field every time a file (e.g. MAIL.EXE) is accessed would be too expensive. The system takes no action on expired files. It is up to the manager to archive them (BACKUP/EXP/BEFORE=TODAY) and delete them (DELETE/EXP/BEFORE=TODAY). ANY file existing prior to the time volume retention is enabled will continue to show No Expiration Date until the file is accessed. R.
