So instead of global variables, it's good form for functions to simply 
use arguments and act upon those?  If this is what you're saying, I can 
see that, since it makes the code more reuseable in scripts that don't 
provide these same [global] variables.

Isn't using a globalized varible just a way to save time/space by not 
having to declare it as an argument?

Always curious about good style,
