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.

BAScript

BAScript is a simple scripting engine written in Object Pascal you can use to add scripting to your Delphi, Lazarus or Free Pascal applications ("host program") to extend their functionality without the need of recompiling them. The virtual machine defines its own language, called the BAScript language. It is a low-level language, somewhat similar to the Assembler language, which is not intended to be easy to program but easy to execute. So it is recommendable to use other higher level languages and translate them into BAScript language. Package includes two compilers that translates from a higher-level language to the BAScript language. You should note that BAScript is intended to be lightweight, so it has not mechanisms to handle complex data structures or large amounts of data or code. On the other hand, it has less need for memory and resources than other scripting interpreters. If you need more power you may try PascalScript.

AppM Build Automation

AppM Build Automaiton is an open source and automated software application that is used to construct and build projects on different operating systems and using different development environments. General principles of implementation: -Each project must have a Build Project File, containing the necessary information on the construction of the project. For example, a unique name of the project, dependence on other projects and libraries, methods of construction, etc. Thus, the entire repository should be marked by the project description files to provide unambiguous information on the projects and their dependencies. - AppM Build Automaiton must be able to perform different actions (project construction, external applications launch, file copying, etc.) which are needed to build a -product. - All operations with projects should be carried out on the basis of information that build tool derives from the project description files.

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.
