If I could get awk to issue a mminfo command, I may give it a try.

Plus, you don't want to do the sort physically since that would mean
moving the same volumes several times. You want complete the sort in
your array without physically moving anything. Then move each volume
once to get it where the array says it should be.

:-)  I've thought of doing this many times over the years, but never
actually written one.  I've often thought that this particular problem
would be a great follow-on to the typical sorting problems that one has
to write in the early undergrad CS classes, because it differs from the
typical sorting in two important ways:

- your "array" may have elements that don't contain anything.
- you may need to use *two* temporary holding spots (two load port
slots)
   in your swap() routine if your jukebox doesn't support direct slot to
   slot moves.

Let me know if someone else sends you one or you write one yourself.  I
would be interested in seeing it too.  Since we don't "Match volume
names to barcodes" here, I would want to be able to sort on either.

Our StorageTek FSEs used to have a program they would use on their huge
silos at another customer's site, to make the robot "look busy" when
tours of VIPs were going through the machine room there.  Having a
"jbsort"
would be even more useful than just having a "jbdance".  ;-)
