You don't get a fresh copy if it's serially reusable.

It actually implies the opposite - RENT modules need additional protection. When you execute a RENT module, you are executing something that may have been loaded weeks ago, and without storage protection may have been deliberately or accidentally modified. If a module is not marked RENT, you get a nice freshly loaded copy every time. -- Andrew Rowley Black Hill Software ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
