AMOS extensions

From ExoticA

This aims to be a comprehensive list of AMOS extensions. It's currently a work-in-progress.


Introduction to extensions

AMOS not only supports its core language, but also allows loading extensions. These are written in assembly code, and they add more instructions and functions to the AMOS language.

Each extension has to be loaded into one of 25 slots. All extensions have a specific slot they're meant to be loaded into. Some extensions work in other slots, but many don't.

When you use extension instructions, the slot number you used gets saved into your source code. If you move the extension to another slot, suddenly your source code doesn't work any more. If you look at the source code in AMOS without the extension, your code just has "Extension M" or "Extension L" or another letter of the alphabet where your extension-specific command once was. When you try and test or run your program, AMOS says "Extension Not Loaded" at you.

Your choice of extensions, along with all other global settings, are stored in AMOS's system configuration file. This is :AMOS_System/AMOS1_3_PAL.env or :AMOS_System/AMOS1_3_NTSC.env in AMOS 1.x, or S:AMOSPro_Interpreter_Config in AMOS Pro.

Default AMOS extensions

These extensions are included with AMOS itself, or included with the official AMOS companion products: AMOS 3D and AMOS Compiler.

They're written by François Lionet, apart from AMOS 3D which was written by Anthony Wilkes & Richard Lewis.
