RE: Remark on the Compiler

Scoping variables is something I've been asking IBM for in RPGIV, but they say
"no one is asking for it" so I suppose it'll never be introduced in my lifetime.
I don't mind the way C++ does it with the :: prefix.
D myVar  S    10A

P myProc   PI
D  myVar      S   3P 0


    //  access the local variable
       myVar += 1;
    //  access the global variable
       if (::myVar = 'COZZI');
    ...

Ok Bob

I agree with what you say , I suppose i was thinking along the lines of
Java where THIS is used to differentiate between local and instance
varaiables.

 

Still it does create quite a difficult to find bug and using a more
strict naming convention may be a way to avoid this. Gxxxx for global
and lxxxx for local variables
