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.

Tiger

Tiger is a Delphi-hosted compiler infrastructure that lets you generate native x86-64 binaries for Windows and Linux — executables, shared libraries, static libraries, and object files — entirely from code. There is no source language to parse. Instead, you construct programs using a fluent Delphi API: define types, declare functions.

Myrissa

Myrissa is a modern systems programming language by Jarrod Davis, combining Pascal readability with robust C ABI interoperability. Written entirely in Delphi, its self-contained compiler generates native x86_64 code for Windows and Linux, with built-in linking, managed strings, unit testing, exception handling, and low-level control.

Ganymede

Ganymede is a high-performance, embeddable scripting engine designed to compile source code directly into native x64 machine code via Just-In-Time compilation. It eliminates the need for virtual machines or interpreters, providing a flat C-style API for seamless integration with C++ and Delphi applications.
