That is because FF(i) expands to F_i() and there is no F_i defined.
Presumably in NEWW(i) the value of i does not matter.  You seem to
want the pre-processor (which runs once when you program is built) to
know about the value of variables at run-time.  It just can't.
 
Back up a bit and explain what you are doing and why you think this is
the right solution.
