Re: Monitor messages (was RE: Hans)

I think monitor works quite nicely for divide by zero, etc.  Actually I 
think the Monitor reads better than MONMSG.  Granted, having some control 
over throwing your own messages would be nice.  But, I'd rather they spent 
more time making IFS access easier.

Has there ever been a good error trapping mechanism in RPG? I do not think 
so.

*PSSR, the error extension on some operations, checking the status, the 
error handlers (CEE API's), never got on in some way.

You could use Receive Programme Mesage and/or Send Programme Message 
API's.

But how do you handle decimal data errors, divide by zero and more of 
those nasty bugs. I think this should have a better method to deal with: a 
"simple" recovery method, in which you could correct the variable in error 
and return to the statement in error to continue.

I have looked at some of those alternatives but not one of them can deal 
with the mentioned bugs properly.

Just my thoughts. I may be mistaken, but then i like to hear how others 
have solved error trapping in RPG properly.
