Don't confuse random access with direct access.

There is no MCCHHHHR, only an MBBCCHHR.

You're confusing the DCB with the DEB. Take a dump and look at what is in

The is no TTTR either.

No; if you were using the normal methods then you wouldn't be having the
problem.

Specifying the extent number implicitly specifies the UCB address, which
in turn specifies the volume.
