Toy Language: Logo
Logo is a programming language dedicated to introduce computer programming to novices. It manages a little turtle on the screen to draw geometrical figures. There are many versions of the Logo language but in this DSL, we use the one presented in the Wikipedia.
At the INRIA/IRISA TRISKELL team, the Logo language is used as an example for the executable metaprogramming language Kermeta. If you are interested on this implementation you can check out the available tutorial.
