AW: Problems with Prototyping and Calling RPGIII Programs

They are identical, because they are both defined in a copy member
that is embedded in every RPGIII and RPGIV source.
In both members an external datastructure is defined on the same physical
file.

We recompiled, we signed off but we get the same failure. MCH3601!
It was not possible to step into the RPGIII program with the debugger.
The failure occured as soon as the call was performed.

The funny thing is: after replacing the prototyped call
through a fixed format CALL the program worked as expected.

My problem is, my manager wants an explication and I really have no idea
what happened.
He already was skeptic when we started with RPGIV!!!
And such things will confirm his opinion ... with RPGIII we'd not get these
problems!

  It sounds like there's a buffer mismatch.  Check to make sure the fields
as defined in the /copy are the same in both the OPM and ILE programs.
