Hi Michael,
I think for your problem you don't even need a nested macro definition.
Just one macro with varying contents of macro variables will do. Nesting
macro definitions only makes sense of you inner macro will have varying
contents, based on conditions in the outer macro. See als my example in the
(two line) URL:

Regards - Jim.
