MSWLogo 6.5b

This introduction does not do LOGO justice but its a start. LOGO is a programming language, pure and simple. There are two models that languages come in, compiled and interpreted.
What is a compiled language?
In a compiled language the program is written and fed to a compiler. A compiler reads all your code and converts it to an executable form that your computer understands.
What is an interpreted language?
An interpreted language does not get compiled; instead, as each line is read by the interpreter it executes it. This is a slow process to execute (on the fly) like this, but has the advantage of not requiring a complete compile for each change. Its ideal in a learning environment.
So have guessed what type of language LOGO is yet?
Right, its an interpreted language; at least this LOGO is anyway.
LOGO also has another unique feature not offered in many other languages (none that I know of). That is, whats called "Turtle Graphics".
What are turtle graphics?
Turtle graphics is a simple and powerful set of commands to manipulate a turtle.
