simplest way... use a recursive function that feeds itself the state as one of its arguments...

Mmm, yes I had thought of that. But I wasn't sure how it would work, as you can't have variables in the same sense as imperative languages. So if I create a mainloop sort of function, that passes the old state into itself, then would I have to modify the output within that fucntion to get it to display to the user, correct? Thanks for the response! Regards, Scott
