Hmmm.   yes, that will work just fine.... in most cases...

Though I'm trying to only /initiate/ a loop with the macro - so the #end of the
for loop is what I need to avoid at the present.
I have not yet figured out if there's a syntax trick that's possible.

like so:
Loop(Fnord,0,10,2)
     [loop contents NOT in macro]
#end

Right - o.  That'll be great.   Especially since I can just use a string
function to look at the extension of the filename and avoid the declare
altogether.   :)
