The 2105 does not specifically say that either a Write Data or a Write Key and Data with a 0 length in the CCW byte count will cause an error if inside a Locate Record Domain, so I think they would work there, but they will cause a Unit Exception error outside a Locate Record Domain. >An EOF can have a key and you could then do an update write (WRITE >KEY/DATA CCW) to change the key, but no access method or program I know >of supports a key on an EOF. The control unit supports this bizarre combination on a formatting write.
