Hello Alan,

What it seems to me is that you are describing nested procedures vs.
procedure calls.

I have not found a way to do a nested procedure in ILE RPG and suspect that
there is not a way of doing it without resorting to some fancy pointer
stuff.

For example in Borland's Delphi I could code the procedures like this to
arrive at the same problem you are having with observability.
var
X1

Procedure  ProcA
Var
SomeChar : Char;
begin
        ProcB
end;

Procedure ProcB
Var
SomeOtherChar : Char;
begin
    ...
end;

Now the variable X1 is visible to both procedures because it is in global
scope. But ProcA can not see ProcB.SomeOtherChar Nor can ProcB see
ProcA.SomeChar

In ILE RPG I would think the way you could get around this is by exporting
the variables that you need to share and only importing them in the modules
that need them. This way you can share the variable's address space between
those procedures that need that sort of communication.

I hope that helps
Eric
