Re: Sockets programming in RPG-ILE

 >> As long as you're on this thread :-) may I ask about error handling in
the
mixed environment (AG QILE vs AG *DFTACTGRP)  I am calling this QILE pgm
from an OPM CL program.  I'm not going to get any nasty surprises, am I?

The majority of the problems in error handling arise when you are
repeatedly crossing the ILE/OPM boundary.  If you have a CL program in OPM
calling an ILE program, doing all of its work and then returning, you're
not likely to see a lot of problems.  If on the other hand the ILE program
represents a frequently called function so that you are back and forwards
all the time you have to be more cautious.  Even so, the major problem lies
with things like coding an error indictor on the RPG CALL and then not
doing anything with it.  The compiler considers that the indicator means
that the programmer wants to handle errors, so any error is "swallowed" by
setting the indicator and will never be seen unless the programmer uses the
indicator.  An OPM program would still have displayed the "Cancel Dump,
etc...." message.

As for other problems, if you do proper error handling you won't have much
of a problem - most difficulties arise with unhandled error behaving
differently.
