RE: OPTIONS(*OMIT)/style question

No I wasn't ... but that can hardly be the first use of RTFM
you've seen--even if not directed at you.

Nope, not in all the years I've been on this list. No, I'm not going to look it up in the archives!

Anyway, IIRC, the FM says that the special value *OMIT will

be passed.

Not really. It says that a null address will be passed
(paraphrasing but that's the gist of it).

Just re - read :

When OPTIONS(*OMIT) is specified, then the value *OMIT is allowed for that
parameter.

I guess that by passing *OMIT, I am expressly stating that

the caller

must not use the parameter. So in my view this seems to be the best
way.

No, you are expressly saying the receiver must not use the parameter.

Sorry, that's what I meant.


So, back to my problem.

I've a program

Parm1 CONST
Parm2 CONST
Parm3 CONST
Parm4 CONST
Parm5 CONST
Parm6
Parm7

Parameters 4 5 and 6 are always passed, 6 being an error message. Parm7 represents an optional pointer to data structure. As parameters 1 to 3 aren't always needed I wanted to use *OMIT on these. I have *NOPASS on Parm7. The program knows when which parameters are supposed to be present. As this may be called by many other programs I thought calling like this :

MyPgm ( *OMIT :
*OMIT :
*OMIT :
Parm4 :
Parm5 :
Parm6 );
OR

MyPgm ( *OMIT :
*OMIT :
*OMIT :
Parm4 :
Parm5 :
Parm6 :
Parm7 );

Would make it perfectly clear that parameters 1 to 3 were not to be used.
