A goto-like usage of a function

[Tim Golden]

| I understand recursion to be a loop or a loop to 
| be recursion... however you prefer to look at it. 
| Whether it's a function calling itself until the 
| user gets the input right or a while statement w/i 
| a function waiting for correct input... IMO, it's 
| the same thing. With that said, there may be 
| performance issues that I'm unaware of that make 
| your approach better or worse  than mine... 
| outside that, I think either approach is worthwhile.

Fair enough. I wasn't sure if you were a novice
who'd seen the recursion as the only way of looping,
or someone who simply chose to recurse. You're free
to choose. I suppose it's just my background which
makes me lean to iteration rather than recursion.
I too am unsure about the performance implications.
