Doh!  There *must* be something wrong with this; it's *way* too simple!  Well,
if you don't want a "tell" message sent to the original session, see my post
on this thread.

(Nice job! I'm not sure what the "continue" before the "bye" is supposed to
do, though.  If the "bye" fails, you want the udc to finish?)

Change the tell to
tell !hpjobname,!hpuser.!hpaccount Someone else is trying your signon.

And, just for fun, add a SETJCW CIERROR 0 before the "xeqtell..." command.
