Re: AW: How to call a RPG program from a RPG program?

[Scott Klement <midrange-l@xxxxxxxxxxxxxxxx>]

The easiest way to eliminate the pointer logic would be to call QCMDEXC 
with a prototype, and use the CONST keyword.

But, I'm guessing the underlying problem was that the programmer thought 
he couldn't call programs with prototypes.  That's not unusual -- many 
people go through a phase where they think that prototypes are only for 
subprocedures.

(There's also a crowd that thinks there's a distinction between calling 
a "bound module" and calling a subprocedure...  believe it or not, there 
are people who don't realize these are the same thing.)

Most will eventually learn ...  but, of course, we all leave behind code 
that was written during the time when we didn't know something, and so 
did it an alternate way.
