Introduction

Logo is a programming language developed in the 1970's by Seymour Papert. It is an excellent language to begin learning with, as it teaches the basics of things like loops, tests, procedures, etc. The user moves an object called a "turtle" around the screen using commands as simple as forward, back, right, and so on. As it moves, the turtle leaves a trail behind it, and so it is therefore possible to create drawings. Operations on lists and words are also possible.

For example, forward 100 right 90 will first make the turtle move 100 steps forward, and then turn the turtle 90 to the right.

This very intuitive graphical approach makes Logo an ideal language for beginners, especially children!

XLogo is a Logo interpreter, written in Java. It supports seven languages, (French, English, Spanish, Arabic, Portugese, German and Esperanto) and is licensed under the GPL.
