How?

RPG doesn't have a mechanism to throw exceptions.  At least not the RPG
I work with (which is, by necessity, a few releases back from the
current GA version).

I use the QMNSNDPM api.  It sends and *escape message up the call stack.

I write very modular code ... but never throw an exception ... exception
throwing is not normal in RPG, so it shouldn't be done except in
extraordinary situations.

In RPG I use MONITOR to catch exceptions and QMNSNDPM to throw them. (
actually in practice I throw exceptions a lot more than I catch them.
I worry too many MONITOR blocks will slow the code.down. )

Who said?  Formats are nothing but a contract between the sender and
receiver.  If you write your client & server properly, and a multiple
formats are required, the server will work out the data format on it's own.

I agree that if you code the dtaq application properly you will not
have any out of the ordinary problems.
