It was derived from the Greek logos meaning word or thought by Feurzeig,2 to distinguish itself from other programming languages that were primarily numbers, not graphics or logic, oriented. A general purpose language, Logo is widely known 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. Tortuga Pc Game' title='Tortuga Pc Game' />The language was conceived to teach concepts of programming related to Lisp and only later to enable what Papert called body syntonic reasoning, where students could understand, predict and reason about the turtles 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 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 the best facilities for handling lists, files, IO, 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. Logo is usually an interpreted language, although there have been developed compiled Logo dialects such as Lhogho and Liogo. Logo is not case sensitive but retains the case used for formatting. HistoryeditLogo was created in 1. Bolt, Beranek and Newman BBN, a Cambridge, Massachusetts research firm, by Wally Feurzeig, Cynthia Solomon, and Seymour Papert. Its intellectual roots are in artificial intelligence, mathematical logic and developmental psychology. The first four years of Logo research, development and teaching work was done at BBN. The first implementation of Logo, called Ghost, was written in LISP on a PDP 1. The goal was to create a mathematical land where children could play with words and sentences. Modeled on LISP, the design goals of Logo included accessible powerclarification needed and informative error messages.

The first working Logo turtle robot was created in 1. A display turtle preceded the physical floor turtle. Modern Logo has not changed too much from the basic concepts before the first turtle. The first turtle was a tethered floor roamer, not radio controlled or wireless. At BBN Paul Wexelblat developed a turtle named Irving that had touch sensors and could move forwards, backwards, rotate, and ding its bell. The earliest year long school users of Logo were in 1. Muzzey Jr High, Lexington MA. The virtual and physical turtles were first used by fifth graders at the Bridge School in Lexington, MA in 1. Turtle and graphicseditLogos most known feature is the turtle derived originally from a robot of the same name,7 an on screen cursor that showed output from commands for movement and small retractable pen, together producing line graphics. It has traditionally been displayed either as a triangle or a turtle icon though it can be represented by any icon. Turtle graphics were added to the Logo language by Seymour Papert in the late 1. Paperts version of the turtle robot, a simple robot controlled from the users workstation that is designed to carry out the drawing functions assigned to it using a small retractable pen set into or attached to the robots body.

As a practical matter, the use of turtle geometry instead of a more traditional model mimics the actual movement logic of the turtle robot. The turtle moves with commands that are relative to its own position, LEFT 9. Some Logo implementations, particularly those that allow the use of concurrency and multiple turtles, support collision detection and allow the user to redefine the appearance of the turtle cursor, essentially allowing the Logo turtles to function as sprites. Multiple turtles are supported by MSWLogo, as well as 3. D graphics. Input from COM ports and LPT ports are also allowed by MSWLogo through windows GUI. Interrupts can be triggered via keyboard and mouse events. Simple GIF animations may also be produced on MSWLogo version 6. Turtle geometry is also sometimes used in environments other than Logo as an alternative to a strictly coordinate addressed graphics system. For instance, the idea of turtle graphics is also useful in Lindenmayer system for generating fractals. ImplementationseditApple Logo redirects here. For the logo of Apple Inc., see Apple logo. Some modern derivatives of Logo allow thousands of independently moving turtles. There are two popular implementations MITs Star. Logo and Northwestern University. CCLs Net. Logo. They allow for the exploration of emergent phenomena and come with many experiments in social studies, biology, physics, and other areas. Net. Logo is widely used in agent based simulation in the biological and social sciences. Although there is no single agreed upon standard, there is a broad consensus on core aspects of the language. As of March 2. 00. Logo, each with its own strengths. Most of those 1. Commercial Logos that are still widely used in schools include Micro. Worlds Logo and Imagine Logo. Apple Logo, developed by LCSI, was the most broadly used and prevalent early implementation of Logo that peaked in the early to mid 1. Atari Logo was released on cartridge by Atari for the Atari 8 bit family. Color Logo was released in 1. Tandy for the TRS 8. Color Computer. Exper. Logo was released in 1. Expertelligence Inc. Macintosh1. 28. K. Hot Logo was released in the mid 1. EPCOM for the MSX 8 bit computers with its own set of commands in Brazilian Portuguese. TI Logo for the TI 9. A computer was also used in primary schools, emphasizing Logos usefulness in teaching computing fundamentals to novice programmers. IBM marketed their own version of Logo PN 6.

Subsequently, George Mills at MIT used UCBLogo as the basis for MSWLogo which is more refined and also free. After that, Jim Muller wrote The Great Logo Adventure which was a complete Logo manual and which used MSWLogo as the demonstration language. The book is now out of print, but Jim has released all the files in pdf format. Check the Logo Foundation website for details. MSWLogo has evolved into FMSLogo An Educational Programming Environment.
