FMSLogo for Windows

Product overview

FMSLogo is a free development application created by David Costanzo. It implements the classic Logo programming environment and has been used for many years in education and hobbyist programming. The program offers an interactive Logo interpreter, a simple graphical interface, and a collection of powerful utilities for working with graphics, multimedia, and hardware.

Visual and multimedia capabilities

• Draws both wire-frame and solid 3D perspective graphics for advanced visualization.
• Supports bitmapped and independent turtle graphics — up to 1024 separate turtles for simultaneous drawing.
• Exports and imports BMP images and can produce animated GIFs.
• Uses system fonts to display text and can create native Windows dialog boxes for user interaction.
• Integrates with multimedia stacks and provides MIDI device control for sound and music projects.

Hardware access and connectivity

• Directly controls external devices using I/O (requires administrator privileges for low-level access).
• Communicates over serial and parallel ports for hardware interfacing.
• Handles TCP/IP networking for networked Logo applications and remote communication.
• Provides facilities for exception handling to manage runtime errors during hardware or network operations.

Extensibility and developer tools

• Calls native dynamic-linked libraries (DLLs) to extend functionality with compiled code.
• Parses and executes Logo code interactively, suitable for learning and rapid prototyping.
• Offers utilities to work with system-level resources and to script complex behaviors.

Suggested alternative

If you need another free Logo implementation, MSWLogo is a commonly recommended option.
