- For a floor turtle, the unit of distance is however far the turtle can

- the TV screen. (Note: on some displays, one dot horizontally may not
- be the same length as one dot vertically. The setscrunch command al-
- lows you to control the relative sizes so that squares come out
- square.) The turtle moves in whatever direction it is pointing when
- you use the command.
