When you DETACH, CP will issue Rewind-Unload to the drive. There is a special UNIT CHECK that a tape drive is supposed to generate if it is in a NOT READY state when a Rewind-Unload is issued AND there is a cartridge in the drive. (What?!? You didn't know that!?!) :-D For a device that isn't really a tape drive, it sure does act like one. Alan Altmark z/VM Development IBM Endicott
