passing along *NoPass arguments

["Jon Paris" <Jon.Paris@xxxxxxxxxxxxxx>]

Steve, *OMIT appears to be the only way to go for your requirement.  It does
of course mean that instead of using %Parms to determine if the parameter
was passed, you will have to check for *Null instead (wouldn't it be nice if
we could check for *Omit - hint hint Barbara!) but it has the advantage that
you can pass on the parm with impunity.

The compiler does not defend against passing unpassed parms - just as it
doesn't stop you from attempting to reference those fields.  Unlike called
programs, attempting to reference an unpassed parm on a bound call will not
necessarily blow up - sadly.  If there is a valid pointer on the stack it
will use it and you'll be passing goodness knows what data.

Seems to me that it would be a nice compiler option to be able to specify
that any attempt to reference an unpassed parm would result in a null
pointer being used.  That would have given you the result you expected.  For
compatibility reasons we're stuck with the current behavior as the default
and I know it would be less efficient, but the current situation is just
plain dangerous.
