Re: Exception message in Joblog

[Dave McKenzie <davemck@xxxxxxxxxx>]

Now I'm confused again (not unusual :-)
The MODEXCP can be used to turn exception monitors on (handle) and off
(skip),
plus several other states (ignore, resignal, defer).  Are you saying
that
originally you didn't have a MODEXCP and it caught the exception, but
still put
the MCH1202 in the joblog?  If that's the case, I don't have an
explanation.

In C, for exception handlers, you can specify _CTLA_HANDLE, and
_CTLA_HANDLE_NO_MSG.  Maybe what you got was the equivalent of the
first, not the
second.
