    Action! Programming Language

    Action! Programming Language

    Action! - The Native Programming Language for Atari 8-bit Computers

    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.
