Extension(s) .alan, .a3c
Released 2002

ALAN 3 is an interactive fiction system first created as a successor to ALAN 2 around 2002[1], and officially replacing ALAN 2 in 2005[2]. As with most interactive fiction systems, it uses two formats: a "source" format, which is human-readable and -editable, and a "compiled" format which is run by an interpreter.

ALAN 3 can by run with Gargoyle using a plugin distributed from the ALAN 3 website.

Contents

Extensions

Source files use the extension .alan, as did ALAN 2. Compiled files use the extension .a3c. Unlike ALAN 2, which is a multi-file format, ALAN 3 games have no accompanying .dat file.

Identification

.alan files have no magic number, but they probably contain the ASCII strings "verb", "isa", "does", "the", "end verb", and "exit", with varying capitalization.

a3d files start with the ASCII magic number ALAN.
