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.
