Carel;

I use them all the time. I have a condition handler that intercepts an
escape message, handles it, and places the relevant information in an
error structure (same as IBMs API error struct) and returns that to the
caller which then will determine how to deal with the error from the
procedure. 

Depending on your process you can set the error handling up as granular
or course as you want/need. You can also create "retry" and "exit" logic
using the C functions setjmp/longjmp. You can also imitate the error
handling of IBM APIs, pass an error struct and error info will be
returned (if one
occurs) otherwise the procedure will die hard.

If anyone is interested I can get some examples together sometime this
week.

Reading this thread I miss the mentioning of the Condition Handler APIs:
CEEHNDLR and CEEHDLU. 

It has to be registered at the beginning of a programme and unregistered
at the end (of course). It requires (a) special procedure(s) to handle
errors.
You can tell what action to be taken: perculate, promote, etc.

Joe Pluta wrote an article in MC on this in 2001.

Are those APIs not intended to do what you want to do? Or is it it just
one of the many (failed?) attempts to get a decent error handling
routine in an RPG programme?

Just wondering.
