I also find it useful to use PrettyCode.Print. It's a 3rd party add in that
er ... prints code. The advantage as far as this thread is concerned is that
it prints the code with nice little lines down the left bracketing the IFs,
DOs SELECTs and so on. If you don't mind the little advert at the bottom of
the page you don't even need to register... which makes it effectively free.
