Pity. If VSI want to consider it, a nice enhancement to VMS would
be to provide an analysis module as part of each VMS-supplied device
driver which would plug into a public documented SDA plugin architecture.

Such a module would allow all the registers and data structures for
the device to be examined and formatted in a human readable format,
including being able to display, in one command, all the data structures
which were part of a specific higher-level data structure listed in
that command.

That way, you would easily, for example, be able to see the contents
of all the TD entries in a queue without having to manually examine
each entry one by one.
