If you actually had a PI/PR for a program with VALUE, you should

have

gotten a compile time error.

No compile-time error because CL/LE doesn't support

prototypes.

Even if one side was CL, the other side would have had to been RPG to

use

VALUE...

You still should have gotten a compiler error on the RPG side..

There was no compile-time error. The RPG service program compiled
just fine with VALUE in the PR and PI. The CL program compiled just fine
defaulting the CALLPRC parameters as ByRef. But at run time the RPG
service program could not receive the parameters from the CALLPRC. As
soon as I changed the CALLPRC to specify ByVal and recompiled, then at run
time everything was fine.
