It's a bit like a crossword puzzle.

And you go from there putting the pieces together.
Giving the pieces names that mean something is the biggest part.
The bit that takes a character that you type in is something that I've never seen.
When you ask for a character most routines that I've ever seen say either, "Yeah, I've got a character for you" or "I have nothing, but let's wait a bit and I'll say no if there's still nothing."
This routine is like a cheesemonger that you ask for cheese and he says, "Maybe I have cheese or maybe I don't, but in either case it will take exactly five minutes to find out!"
