Re:

Why?  At first glance, I can see no reason to want to do this...the
information you get back wouldn't seem to be too useful.  E.g., if you
have MPEXL_SYSTEM_VOLUME_SET with classes DISC and FRED, and USERS with
classes DISC and SALES, "FRED" and "SALES" aren't interchangable...a file
can only be put on disk in a class in the one volume set the group is HOMEVS'd
to.

I suspect you could create an MPEX script (or sh/grep/cut :) that would
do what you want:

   DSTAT ALL
and manipulate that.

Here's an awkward example.  It's awkward because of the @#$%^ incompatibilities
between the shell and the rest of the world.  Specifically, "callci VOLUTIL ..."
usually fails on my 6.0 system because VOLUTIL is unhappy about the output file
(I think).  Other attempts to have a shell-only solution resulted in multiple
"waitany pid" error messages (Mark Bixby is familiar with that problem!).

So, I created two files:

   /usr/local/bin/classes.part1            (marked:  chmod +x)
and
   CLASSES.CMD     (in my HPPATH path)

/usr/local/bin/classes.part1 is two lines (the second line is a longgg line):
   rm -f /tmp/classes.tmp
   callci "DSTAT ALL" | grep " MASTER " | cut -d "(" -f2  | cut -d "-" -f1  |  xargs -iX echo volutil \"showset X classes\" >> /tmp/classes.tmp

CLASSES.CMD is:
   run sh.hpbin.sys;info="/usr/local/bin/classes.part1"
   xeq /tmp/classes.tmp
   purge /tmp/classes.tmp

Obviously, two users couldn't use this at the same time.

Here's a sample run:

   :classes

You could add code to strip the blanks, and the VOLUTIL/MIRVUTIL prompts.

Note that I avoided "END OF PROGRAM" from the "sh.hpbin" by using
XEQ instead of RUN....I couldn't safely avoid that via an implied run,
because both "sh" and "sh.hpbin.sys"
might trigger someone's "sh" UDC/command file, getting incorrect results.
