difference between function and command and sending parameters

Thanks Eric. It sure helps to get a simple explanation like that in addition
to the docs. It seems like I can never understand any simple program concept
and use it properly without lots of examples and simple explanations.
But what if the function "CurrentUsers" is in a card in some other stack
that you are using?
then how do you say: quote return "William" is among the lines of
CurrentUsers() of card "othercard" in stack "mystack" end quote?
