This is a simplified version of the programming language Logo. Use it to draw shapes by moving the turtle (arrow) around the screen using the following commands:
Example: fd 10 will move the turtle forward ten steps.
Example: bk 5 will move the turtle backwards five steps.
Example: rt 90 will turn the turtle 90o to the right.
Example: lt 45 will turn the turtle 45o to the left.
The turtle can move without drawing a line.
Example:
repeat 4[fd 10 rt 90]
will draw a square.
Example: pc 2
0 = black, 1 = blue, 2 = red etc
