Re: Latest RPG Updates

Jon,

Assuming the FORMAT procedure and its candidate procedures are all in a service program, how do I use it in another RPG program?  I would guess that I have to put the prototype in the RPG program, yes?  Do I have to put all the candidate prototypes in there too? My thought was the RPG program using it would simply have

Dcl-Pr Format Override( ProcA, PgmB, JavaC );


but now that I put it that way, the compiler would have to go to the service program to check my usage against each of those candidate prototypes to see if it's allowed.

FORMAT is never exported because it is only really a compiler directive.

For example thing of it this way.

Dcl-Pr Format Override( ProcA, PgmB, JavaC );

This is handled by the compiler much like a conditional compilation directive such as ...

/IF ParmMatches ProcA
CallP ProcA(parm);
/ELSEIF ParmMatches ProcB
CallP PgmB(parm);
/ELSE
....

It is that simple.

Is FORMAT exported? There will be times when I want it exported and other times I don't. My best guess is that it inherits from the actual procedures.

Actually it doesn't matter if the procedure is exported or not. In fact the overloaded routines can include programs, Java calls, and subprocs.
