Re: How do you pass an omitted parameter to a procedure? -- RPG400-L

Personally I would say this should be flagged as an illegal operation. I suspect the number of customers affected by any compiler changes is probably limited to one <grin>

I am amazed that it actually allows this for *Omit and find the * syntax rather confusing since it looks like a multiply operation with no operands. Don't think I'd have ever guessed from reading the code that that was what it was doing.

However - if they do fix the compiler (or even if they don't) I would really like to see the way *Omit is handled in the receiving program/procedure get fixed too. It always seems to me you should be able to say:

If parmName = *Omit; // or *Null for that matter

or even

If %Addr(parmName) = *Omit;

The current requirement that you pass *Omit on the call and then test for something completely different has always seemed a little silly to me - but so few people use *Omit at all that there's never been any real demand for change.

This is a survey that I started as a result of an APAR that I opened at
IBM. The actual problem I have is that RDI 9.0 issues a warning for the

"Outline" view.

sendMessage(*: THIS); // - unexpected token(s) ignored
sendMessage('Hello': *); // - unexpected token(s) ignored
sendMessage(*); // cannot detect whether or not it is
// a procedure call or an indexed array
sendMessage(); // legal statement

Now IBM says that the compiler causes the problem, because actually it
should not accept the '*' as a replacement for '*omit'. Finally they asked
me whether or not I want to open an APAR to fix the compiler. Since
changing the compiler would cause a lot of work for us I am not sure what
to do and I like to know whether or not you were affected when IBM changed
the compiler.

Please select:

[ ] Not affected, let IBM change the compiler

or

[ ] STOP, never change the compiler

Feel free to add additional comments.

Thank you.

Thomas.
