Begin by typing FORWARD (or FD), then a space, and a number. You can also type BACK (BK), RIGHT (RT), and LEFT (LT). All of these move or turn the arrow (called a turtle). Type HIDETURTLE (HT) to make the turtle disappear. To make it reappear, type SHOWTURTLE (ST). Type HOME to bring the turtle back to the middle of the screen. Type DRAW or CLEARSCREEN (CS) to restart. You can type PENUP (PU) to make the turtle stop leaving a trail. Typing PENDOWN (PD) makes the turtle leave a trail again. After every time you type, press the enter key.
