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

Just re - read :

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