Though A-code is not by any stretch of imagination (and despite its virtues)
a popular IF language, you never know – the built-in browser mode,
brave soul or two. Hence this page.
Not included are a few things, which as a putative user you are expected to
provide on your own:
- A text editor of your choice
- An ANSI C compiler
- And if you wish to try your hand in creating new games:
a dash of creative imagination.
Complete A-code system sources and documentation are supplied as a single
tarball (mipmip.org/acode/acode-12.79.tgz). Please see the tarball description document for

Building games from source
Firstly, let's deal with building runnable games from A-code source files
and the ways of running such games, once built.
A-code build types explained
Acode games can be built in five distinct ways: console, combined
browser/console, single-turn (for running in a cloud in a CGI, PHP or
what all these build types are are and what they are for.
Using the advbld script to build A-code
Since this file is a part of my A-code framework bundle,
you clearly have the advbld script installed. This document explains
how to use the script to build A-code games in various modes, so you don't
have to bother with the "how" of it.
Running A-code games
The A-code kernel understands a number of command line options, though some
of these need active support from the A-code source. E.g. adv550 does not
understand the name of a game save-file to restore being supplied on the
command line, and may land the player in limbo, with no source of light.
If you cannot or do not wish to use the advbld script for building
games, here are a couple of document explaining how to do it in a more
Translating A-code source into
compilable C code
To build an A-code game from its A-code sources
(files suffixed with .acd), you first have to use the acdc
translator to create derived C sources. This document explains how.
Creating an executable from
derived C sources
Once you have created (or downloaded) derived C
sources of an A-code game, you are ready to create various modes of
executables. This document explains how. (See a
separate document for an explanation of build modes.)

The library mode interface
In the ADVLIB mode, the A-code kernel presents itself as a
function called advturn. This document describes its
functionality and calling sequence.
The CONTEXT mechanism
A-code game is to run in a cloud, which is very useful for
beta-testing, it must not use the the QUERY directive. This
document explains how the CONTEXT variable can be used to avoid
use of QUERY. (The no-QUERY restriction may be removed in a future
version of A-code, in which case this page will become obsolete.)
Upward compatibility of saved
A-code is unusual in that with a little care a
game author can ensure that saved games are upward compatible and
can be loaded by later game versions. This document explains how.
Finally, some history... A-code
