error as long as you have not yet written any new files onto the
disk. ('!'hat is, you have not yet caused CMS to rewrite the master
file directory.) Reissue the ACCESS command without the ERASE option. q. You should never attempt to access a disk in read/write status if
another user already has it in read/write status; the results are
unpredictable.
Q. When accessing as and DOS disks: a. You cannot specify filename, filetype and filemode when you
access as or DOS disks, nor can you specify any options.
b. In order to see as and DOS disks, you must have a read/write CMS A-disk available if you are going to use the LOAD command
with the MAP option. (MAP is a default option.) 10. If two or more disks have been accessed in CMS, and CP DEFINE
commands are executed that swap virtual addresses, then a
subsequent RELEASE command may write the master file directory on
the wrong aisk: for example: (CMS) (CM S) (CP) (CP) (CMS) liCCESS 193 C ACCESS 198 E
