The best thing to do is to have an IBM SE look at this and take a stack trace to
determine what component is causing the problem.  Also, they can record the
address of the instruction so as to determine the offset into the code that
'asserted'.  Another thing you can do is type in "quit dump" instead of just "quit".
This will force a dump to your primary dump device which you can then hand over
to your IBM rep.
