ILE Application Using CRTRPGMOD

with programs in different activation groups. If you want file across activation groups, you must open it at the j specifying SHARE(*YES) on an override command or create the file with SHARE(*YES).

Errors	When	you		call	an ILE RPG	program or procedure in the sa
	vation		group,		if it gets an exception that would previous
	caused		it to		display an inquiry message, now your calling
	will	see		that	exception	first.

If your calling program has an error indicator or *PSSR, t program or procedure that got the exception will end ab without the inquiry message being displayed. Your calling will behave the same (the error indicator will be set *PSSR will be invoked).

When you call an			OPM program or		a	program	or main procedu
in a	different		activation	group,	the exception			handling wi
same as in OPM RPG, with each program handling its own
exceptions.		The	messages	you see may have new				message
so if you monitor for a				specific		message	ID,	you may
change	that	ID.

Each language processes its own errors and can process t errors that occur in modules written in another ILE langua example, RPG will handle any C errors if an error indicat been coded. C can handle any RPG errors.
