It's possible to occasionally and unpredictably get %Addr(Parm2) <>
*null when the parameter isn't passed.

If %Addr(Parm2) = *Null;
 // *Omit was used or there's a null pointer where Parm2 would have been
passed
Else
 // Parameter was passed or there's a valid pointer where Parm2 would
have been passed
EndIf;

Using that method is dangerous when the program is changing Parm2.  It
might change "something" that it shouldn't.
