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

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.
