Early on it talks about storing UDG data inside the code in safe places and accessing it. Then how to put the maze data into a DIM. Then a faster way - store the screen image instead, since it's way faster to put up as a screen$ type block. Then function fastHalfSquares is discussed, which contains a data table, as well as the code that accesses it - and so on.
Hope it helps!
