Action! Programming Language

Action! is a programming language for the Atari 8-bit family of microcomputers. It features an integrated editor, a debugger, and a 6502 compiler. Action! was created by Clinton Parker and released on cartridge by Optimized Systems Software (OSS) in 1983. Its syntax is similar to that of ALGOL 68. Action! is significant for its high performance, which allows games and graphics demos to be written in a high-level language without the use of hand-written assembly language code. Action! language constructs were designed to map cleanly to 6502 opcodes. In 2015, Clinton Parker released the Action! 3.6 source code to the public under the terms of GPL. This project is intended to preserve the Action! source code, provide fixes for known bugs, and add new features in version 3.7. Join us at AtariAge https://forums.atariage.com/topic/217770-action-source-code for questions and discussions. Check out https://atariwiki.org/wiki/Wiki.jsp?page=Action for related information.

MPL Bytecode Compiler

NEWS: The MPL language is now completely defined. No more language changes are to be made. The compiler is complete and should be easy to translate to other languages if you so choose. MPL is a small, simple language based on BCPL, B, C and Jesusonic. The compiler and interpreter are written in portable Pascal. I have successfully compiled MPL for CP/M, DOS, Windows, Atari ST, Amiga and the Tandy Colour Computer. MPL is designed to be tiny in every way, while implementing all the important features of BCPL & B. The result is a compiler written in a high level language (PASCAL) which compiles to under 16K (CP/M). The symbol table, language syntax, and bytecode are all optimized for size. I will write a MPL Reference Manual in time. Contact myself if you want to help get that written.

CodeSnip

CodeSnip is an open source code bank for storing and viewing code snippets. It not only manages, displays and manipulates your own code snippets but it can also incorporate snippets downloaded from the online DelphiDabbler Code Snippets Database. > CodeSnip's source code is now developed over on GitHub: https://github.com/delphidabbler/codesnip Designed with Pascal code in mind, CodeSnip enables Delphi or Free Pascal code snippets to be test-compiled with any installed Delphi or Free Pascal compiler and results to be reported. Use this feature to validate the syntax of code without switching to your compiler. Compilable Pascal units containing selected snippets can be generated. Code in other languages can be stored in CodeSnip although the source file generation and compiler checking features will not be available. Compilable Pascal units of selected snippets can be generated. Selected snippets can also be exported and shared with other CodeSnip users.
