Subject Re: variables or a counter ?

Just a note, be careful about recursively calling a macro...  You will 
eventually get a stack overflow.  I did something like this with a 
simulated for-loop using Ant Contrib's Math task.  I found after around 
300 - 400 iterations I'd get a stack overflow...
