[Tutor] help on scope

that's a good tip even it looks a little clumsy.

I'm writing a little program that makes anagrams. Something I failed to do 
miserably in basic when I first dabbled in programming 20 years ago. I'm 
using count to help me check whether the algorithm is working properly. As I 
use a recursive function I need to initialise my counter outside the function 
but increment with each new word. Passing the counter as an argument removes 
problems of scope but feels wrong. I agree, however, that it is better than 
using global. Am I missing something?
