allow you to omit the parameter:

very interesting... will this work with both parameters, too? i don't
think i need it in this specific situation, though... i'm mainly wanting
to provide the original unmodified routine and my modification of it so
i can return something to that 3rd party library development...
Yes, provided that you don't also try to have a procedure with no
parameters. In general, the compiler will tell you if you're doing
something silly.
Assume that this is for value parameters only. In particular, I don't
think there's a way of defaulting a var parameter to a nil pointer.
