Problem: The VERIFY command always finds hard disk errors with
large cylinder numbers

Diagnosis: VERIFY uses the DSKOP% jsys which will not access the
last few physical cylinders on a disk. For instance, there are
411 cylinders on an RP04, but TOPS-20 only uses the first 400.


Solution: Change the VERIFY code in FORMAT to only verify the
cylinders that TOPS-20 can use.
