Introduction

There are limited commands in Little Turtle for younger students. They are limited versions of the move, left, and right commands.

• M (move 2 steps)
• L (turn left 45°)
• R (turn right 45°)

Note: The color, size, up, down, home, xy, bearing, and circle commands are not effected.

The limited commands are disabled in Little Turtle. There are two ways to enable them.

1. To permently enable the limited commands, edit the file turtle.js and change the global variable cmdLimited to true.

2. To temporarily enable the limited commands, add a parameter to the URL. http://server/turtle.html?limited
