Thanks to all of you! In fact, I sort of came to this same conclusion. I 
started with a class, but realized there wasn't much of a point since 
I'm just doing some 'work' and returning the cryptogram.

I might try the other suggestion too about convert_quote = make_code, 
that might be ok. Or I can simply call make_code.

Thanks!
