Unfortunately, I don't understand the explanation below -- more precisely, I
don't understand what it fixes. Can anyone explain the need for this Feature
Request to me?
I just cannot grasp what it serves to mark a tape Used when it has been unused
for a certain period.
It also seems to me that ANDing together two different directives is a new
concept, which could add complexity to the existing plethera of directives.

Kern
