Re: RFE - Enhance CL/ILE CALLPRC command to support External Programs

Alan,

You're using CALLP implicitly...

Just like

myvar = someVar;

Uses EVAL implicitly...

dcl-pr MyProc;
var char(9) const;
end-pr;

CALLP MyProc('Hello');

is exactly the same as
MyProc('Hello');


While it's true you can't explicitly use CALLP when the procedure returns a
value; without losing said value. That doesn't mean that you're not using
CALLP.

Sorry, why do CALLP when I can simply do.

dcl-pr GetCount ExtProc('CLPROC');
PR_Field1 Char(9)
end-pr

GetCount(Field1);

why do I need CALLP?

dcl-pr GetCount Int(10) ExtProc('Cpro');
PR_Field1 Char(10);
end-pr;

How do I call this using a CALLP? I can't without discarding the return
value.

If I can prototype any call, then I don't need CALLP.

​Alan,

CALL is obsolete...

CALLB is call bound prcoedure & is also obsolete

CALLP is call using prototype; and is the only call you should be using.

In what circumstances must you use a CALLP?. What call cannot be
prototyped?

Why would you use CALLP in RPG? It has been obsolete for twenty

years.

Incorrect -- for more than one reason. It is optional in

certain

circumstances and required in others.
