RPG II does not have a CALLP op-code. And whenever I use CALL, the compiler
listing gives me a warning (basically, "Are you really sure you want to do
this?").

If an RPG IV defined by activation group *Caller has prototyped procedures,
could it be called by an RPG II program without incident (i.e., bad vibes)?

But maybe I did not correctly understand Jon and Charles. As I read the
thread, if an RPG IV program is (at least explicitly) defined with the
Default activation group, it could not even have prototyped procedures.
Period.

Just curious. Never done that. Do not plan to do that.

Are you using CALL to call external programs or are you using CALLP to call
prototyped subprocedures (not subroutines)? CALL is a totally different
animal from CALLP.
CALLP is more tied to activation groups than CALL is.
