SETSPEED determines the speed at which the turtles or bitmaps move on the screen when being issued a movement command. SETSPEED accepts a number from .1 to 1 as an input. A speed of 1 is the fastest speed and .1 is the slowest. When Logo starts, the turtle speed is 1.

SETSPEED slows down the execution speed of any movement commend. To have the turtles and bitmaps move independently, use the SETVELOCITY command.

To retrieve the current speed, see SPEED.
