I think it was Greg Veal (the author of the CL book) who came up with the
msg queue. He also did something similar with debugging a "remote" job.
"Remote" meaning "another" in this case.

Well, to continue off topic:

There is yet  a n o t h e r  trick to make the SysReq line do interesting
things.  I thought it was Bob Cozzi who came up with it.  It involves
creating a temporary message queue object in QTemp and then send a message
to that queue via the SysReq line with option 5 and using the temporary
queue name.

The message you send to the queue is then interpreted, via a break program,
as a command.  You can basically make it do anything you want, according to
the logic of the message queue break program.  

I am surprised that Bob wrote a hook into the SEPT to accomplish similar
tricks.  Of course, I never heard of the SEPT until I read Leif's book.  

Anyway, Steven, if you want details on the message queue trick, feel free to
contact me off list.  The other tricks I had never heard of.  Anyway, these
things are still useful, although of course not essential.
