"I was one of the authors of that book so I am familiar with the technique
- but it doesn't fully meet the need. Unless I am mis-membering I'm pretty
sure that the problem was that Monitor will only see a single error code as
a result. For a THROW type operation to really work well you need to be
able to designate the exception code. That way MONITOR can be coded to
monitor for specific exceptions. There is an open range of error codes not
used by RPG that could be made available for this purpose."

ON-ERROR could also be changed to accept specific message IDs.

MONITOR;
...
ON-ERROR 'XYZ0001' : 'CPF1234';
...
ENDMON;
