I should have been more specific.  In native I/O, put an indicator on the
WRITE or UPDATE in the error column. Or use %error in RPG IV.  You then have
trapped the I/O error that occurs.  Then it's up to you to deal with it
however your program sees fit.

Is the "standard message handler" mentioned here an RPG program or CL?  Does
it only check for 3 messages, or is that just a subset of it's capabilities?
