MSWLogo 6.5

Apply the techniques of symbolic computation by manipulating of words and ideas in a Logo-based programming environment based on the LISP programming language and using multiple calculations, integrity testing and data search procedures for project completion.

Logo is an interactive programming language for adventurers of all ages. It has borrowed the techniques of symbolic computation – the manipulating of words and ideas – from LISP, the programming language
in which Logo was originally written.
These techniques are combined with other powerful ideas such as the use of procedures, recursion, and the manipulation of programs as data to provide a unique interactive programming environment.
