  Undefined variables

I am trying to create a macro:

   #macro BlurredReflection(InPigment, InFinish, InNormal)
     ...
   #end

But I don't want to *always* pass a value to the macro. Is there a way 
to pass a "null" or "nil" value to the macro, and then check for it 
using a conditional statement?

Thanks.

Mike
