Back in ancient days when I worked with tape drives, the wizards at the divisions that made the drives decreed (in their infinite wisdom) that only on-line events caused host interrupts. Off-line events did not. If this is still the case, it explains why SHOWDEV doesn't change when you remove the tape. It doesn't know you did. -Larry "supported serial disc in another life" Byler-
