Re: User-generated errors

That would certainly be an improvement Barbara - but personally I'd rather stay "within the language".

In other words it doesn't make a lot of sense to me to have to go outside the language and use an API to cause the exception so that you can monitor it with a language feature.

Now of course if you'd like to do both ...

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;
