BTW, you probably want to learn why global names are a bad idea, I don't
have time to explain that here (or point you at references).  Going
through some of the online tutorials should address this.

"...string iteration isn't about treating strings as sequences of strings, 
it's about treating strings as sequences of characters.  The fact that
characters are also strings is the reason we have problems, but characters 
are strings for other good reasons."  --Aahz
