OPTIONS(*OMIT)/style question

[David FOXWELL <David.FOXWELL@xxxxxxxxx>]

Hi all,

I am often finding that I am declaring a local variable just so I can call another procedure. In that case, the called procedure wouldn't use the variable. I see other programmers who don't declare the variable but just pass 0 or ' ' or *BLANK, etc.

Example

D client_type  S           LIKE ( REF_client_type )

client_number = 1;
MyProc (
                client_number :
                client_type   );


Instead of :

client_number = 1;
MyProc (
                client_number :
                '  '       );

I don't like this method as I often see this kind of thing :

MyProc (
                client_number :
                '  ' :
                0 :
                client_info  :
                more_client_info  :
                ' ' :
                );

Here one can only presume that the parameters with ' ' or 0 aren't used. In my first example, I can see that client_type isn't initialised so isn't being used, although it probably still needs a comment. Also when I declare the local variable, I use the same reference field that is used in the prototype.
D MyProc         PR
D client_number  S           LIKE ( REF_client_number )
D client_type    S           LIKE ( REF_client_type )



I just wondered if this is what *OMIT is for?

MyProc (
                client_number :
                *OMIT :
                *OMIT:
                client_info  :
                more_client_info  :
                *OMIT :
                );

Thanks.
