Logo (programming language)
Logo is an educational programming language, designed in 1967 by Daniel G. Bobrow, Wally Feurzeig, Seymour Papert and Cynthia Solomon. Today the language is remembered mainly for its use of "turtle graphics", in which commands for movement and drawing produced line graphics either on screen or with a small robot called a "turtle". The language was originally conceived to teach concepts of programming related to Lisp and only later to enable what Papert called "body-syntonic reasoning" where students could understand (and predict and reason about) the turtle's motion by imagining what they would do if they were the turtle. There are substantial differences among the many dialects of Logo, and the situation is confused by the regular appearance of turtle graphics programs that mistakenly call themselves Logo.
Logo is a multi-paradigm adaptation and dialect of Lisp, a functional programming language. There is no standard Logo, but UCBLogo has best facilities for handling lists, files, I/O, and recursion in scripts, and can be used to teach all computer science concepts, as UC Berkeley lecturer Brian Harvey did in his Computer Science Logo Style trilogy. For tertiary level teaching, however, Logo has been superseded by Scheme, and scripting languages.
MSWLogo
MSWLogo is an interpreter language based on Logo, with a GUI front end. It was developed by George Mills at MIT. Its core is the same as UCBLogo by Brian Harvey. It is free software, with source available, in Borland C++.
MSWLogo supports multiple turtles, and 3D Graphics. MSWLogo allows input from COM ports and LPT ports. MSWLogo also supports a windows interface thus I/O is available through this GUI- and keyboard and mouse events can trigger interrupts. Simple GIF animations may also be produced on MSWLogo version 6.5 with the gifsave command. The program is also used for educational purposes. Jim Muller wrote The Great Logo Adventure, a complete Logo manual using MSWLogo as the demonstration language.
MSWLogo has evolved into FMSLogo: An Educational Programming Environment, a free, open source implementation of the Logo programming language for Microsoft Windows. It is released under the GPL and is mainly developed and maintained by David Costanzo.

MSWLogo, as of v6.5b, has following support of various functionality:
