ProLOGO is a LOGO-like language written in swi-prolog with XPCE graphic libraries. Almost all the basic commands are implemented but there is no support for procedures (yet).

ProLOGO commands can be given in english or in italian. For example it is possible to write:

repeat 4 [ forward 100 right 90 ]


ripeti 4 [ avanti 100 destra 90 ]

ProLOGO is not a complete LOGO language because there's no procedures implementation. We hope someone will help us to develop the project

Hey... they write about us in the site "Programación Lógica y Recuperación de Información"
