Re: Optional Parms in Sub Procedure

Rory,

Were you bitten by a RTNPARM as a child? :-) Why do you hate them so
much?

This lets you use a parameter to send a return value, making it much
more efficient, but still allowign you to use the output in expressions
and other things. It's extremely useful, and I doubt that it required
very much in the way of work for IBM to implement.

Plus.. you don't even work with RPG for a living anymore, do you?

So why does this bother you so much?

Sorry Jon, I think of it as a solution in search of a problem. I never

had

an issue with large parameters (mainly because I passed them as

parameters

rather than as return values). I would rather then RPG budget have been
spent elsewhere...

"nonsense" ?

Sorry - don't agree Rory - it is a terrific feature and can provide a

huge

performance boost.

And if you "do it right" and use RTNPARM there is no problem - at least
within RPG.

Yes, use %PARMS

If you're on 7.1, you can use it in conjunction with %PARMNUM, too.

if %PARMS >= %PARMNUM(MyParameter);
// parm was passed
endif;

on older releases you have to know the parameter number.

if %PARMS >= 5;
// parm number 5 was passed.
endif;

All,
In a sub procedure, I have some parms defined as *nopass.
How do I test the number of parms passed to it?
Can I use %Parms?

Thanks,
