Lim,

Have you tried to check the address of a *nopass parameter if it wasn't passed? I get *NULL when I check in my test program and the program doesn't break.

Subject: Re: Calling similiar (overloaded) procedure that has *nopass *omitinthe parameter

I think the problem is on the *nopass parameter. A *nopass parameter could
have a non-null address even when caller is not passing the parm. But if
you attempt to access the parm, the program breaks. That is the reason why
we can't simply check "if %addr(param) <> *null" for *nopass parameter. For
a *nopass parameter, we have to also check if %parm(param2) <= 2 .... quite
annoying....

Basically I mean there's no way to define a standalone null capable
variable...

Using *OMIT:*NOPASS means jumping though hoops when you need to just
pass them along to other procedures...

In the OP's case, I could see where better null support would allow
proc1 to just call proc2 (disregarding the differences in type for
parm1).

No idea what this means. Can you elaborate?
