Open Source BASIC Compilers for BSD

Open-source, free, multi-platform BASIC compiler, with syntax similar MS-QuickBASIC (including the GFX statements), that adds new features such as pointers, unsigned data types, inline assembly, a pre-processor and many others.

GCBASIC is an open-source BASIC compiler for 8 bit Microchip PIC, Atmel AVR legacy, AVRDx and LGT microcontrollers. See https://ko-fi.com/post/The-Story-of-GCBASIC-Making-Microcontroller-Progr-D1D319SJ72 for story of GCBASIC. This is a continuous release project. The latest release is always available. This will give you the most complete development toolchain to create and program 8-bit PIC, AVR and LGT microcontrollers. We have added new capabilities that make GCBASIC the easiest tool set available - supporting over 1400 microcontrollers with tools to make this fun and simple. Please see the download section for your options. We have two IDEs, we have just the compiler and we have a minimal install - it is your choice. Please see the homepage here: https://gcbasic.com

X11-Basic is a dialect of the BASIC programming language with graphics capability that integrates features like shell scripting, cgi-Programming and full graphical visualisation into the easy to learn basic language on modern computers.

The purpose of this project is to create and update a beginners guide to FreeBASIC. Over the years I have noticed that there was only three real ways to learn FreeBASIC. The FreeBASIC Documentation, the FreeBASIC Community Forum, and A old beginners guide written by Richard D. Clark and Ebben Feagan. Each of these sources are great, but they all assume some experience with a programming language. This Project is taking Richard D. Clark's and Ebben Feagan's "A Beginner's Guide to FreeBasic" and is editing, updating, reorganizing, and simplifying this guide. Mr. Clark and Mr. Feagan generously open sourced there guide so I could start this project. Without being able to stand on their shoulders I could not have even started this project. Please check out my homepage for updated information and ways you can help with this ongoing project. If you can please buy me a hamburger as it is hard writing a book.

A compiler and cross-compiler for (Currently) Cobol (with Fortran being added later). It is intended to be the first self-hosted open-source Cobol Compiler, e.g. the compiler itself will be written using Cobol.

nbasic - bytecode compiler+vm for middle level programming language, like basic. nbs - small and fast C-coded object orientated basic (compiler+vm) for embeded applications. Purpose: scripting support for C/C++ project.

Modern object oriented Basic compiler, generates equivalent C++ code, maganing QT widgets and classes natively.

Elice is a free compiler for programs written in the proprietary language PureBasic. It compiles those programs to C++ and then uses g++ to generate an executable. This is an old version. Development has moved to https://gitorious.org/elice/
