FMSLogo is a free implementation of a computing environment called Logo, which is an educational interpreter language. GUI and Extensions were developed by George Mills [1] at MIT. Its core is the same as UCBLogo by Brian Harvey. [1] It is free software, with source available, written with Borland C++ and WxWidgets.
MSWLogo has evolved into FMSLogo: An Educational Programming Environment, a free, open-source implementation of the language Logo for Microsoft Windows. It is released under the GNU General Public License (GPL) and is mainly developed and maintained by David Costanzo.
Logo's most-known feature is the turtle (derived originally from a robot of the same name), [5] an on-screen "cursor" that shows 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).
MSWLogo and its successor FMSLogo, for Microsoft Windows, are commonly used in schools in the United Kingdom and Australia. [citation needed] For input/output (I/O), text may be written to the command window (output stream) using print and to the graphics window using label. Animations require both the ability to draw and to erase shapes.
Turtle graphics are often associated with the Logo programming language. [2] Seymour Papert added support for turtle graphics to Logo in the late 1960s to support his version of the turtle robot, a simple robot controlled from the user's workstation that is designed to carry out the drawing functions assigned to it using a small retractable pen set into or attached to the robot's body.
MicroWorlds is a family of computer programs developed by Logo Computer Systems Inc. (LCSI) that uses the Logo programming language and a turtle-shaped object to teach language, mathematics, programming, and robotics concepts in primary and secondary education.
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
MicroWorlds JR is a computer program using a simplified version of the Logo programming language to teach non-readers or early readers to program in Logo. It was first launched in 2004 by Logo Computer Systems, Inc. (LCSI), and as in their original line of MicroWorlds programs, the object on the screen begins as a turtle and can be controlled with basic commands to make it move.
