Tiny Pascal for TI83p and TI84

Tiny Pascal for TI8x is a full Pascal and Assembly language tool chain for Texas Instrument TI-8x calculators. It allows production of programs and application for TI83+ and TI84 calculators. The benefits are : · All the features of assembly programs and applications are available without the inherent complexity on Z80 assembly programming · Programs will run much faster that TI-Basic equivalent · A standard library is available (gotoxy, ClrHome, flush, crlf, …), and it will be expanded when needed · Built in access method to TI8xPlus system routines from Tiny Pascal programs · TI-8x menus support To show what you can do with this tool chain, we have coded an Othello/Reversi like game.

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.

.Net Native Interface Library

The .Net Native Interface Library (DotNetNativeInterface) is a native programming interface which provides a way for programming languages such as C, C++, Fortran, Assembly, Pascal, Java, VB etc to interact with applications and libraries written in any of the .Net languages (such as C#, VB.Net etc). Programmers can use DotNetNativeInterface native methods to access .Net 3rd party libraries or .Net Framework Libraries without the need for registry entries, COM registrations or changes to the .Net libraries. The following examples illustrate when you need to use DotNetNativeInterface native methods: 1. You want to access and use .Net Framework Class Library in your application. 2. You want to access and use 3rd party .Net Libraries in your application. Competitive Advantages: 1. Access to .Net Framework Class Library. 2. No COM registration of .Net Libraries is required when deployed. 3. Allows any programming language to consume .Net libraries as if they were native code.
