... because DIRECTXA looks at the ALLOCATION MAP on the volume to find the DRCT area. Kind of prehistoric, after a fashion, but it makes sense when you remember that DIRECTXA is also designed to run standalone. As an experiment in the lab (always wear eye protection and use a fume hood): 1. Create a 1-cyl minidisk immediately in front of the DRCT area 2. Create a mindisk that deliberately and with malice of forethought overlaps both areas. 3. Link the 1-cyl disk, CPFMXTXA FORMAT, then DETACH 4. Link to the the mdisk that overlaps BOTH. 5. Then CPFMTXA ALLOC cyls 1-END as DRCT. In theory, you now have a minidisk that doesn't expose the entire volume but can be used by DIRECTXA. It'd be nicer if DIRECTXA had an option to say "I know it's a minidisk. Now shut up and use it." Alan Altmark z/VM Development IBM Endicott
