- setscrunch -- Command, one input. Abbreviation: setscrun
- This command is used only for display turtles. The input must be a
- number. The vertical component of turtle motion is multiplied by this
- number before each motion is taken. If squares come out too wide on
- your screen, you should increase the number; if too tall, you should
- decrease it. (You can also use setscrunch to deform the turtle's mo-
- tion on purpose, so for example a circle program will draw an ellipse
- instead.) The initial scrunch value depends on the terminal you are
- using: for the Atari and the Gigi, it is around 0.8 (your particular
- computer center will adjust this for the particular TV monitors you
- use), but for the ADM, Tektronix, and Sun, it is 1.0 because these
- terminals display the same size steps horizontally and vertically.
