Module Code Definitions                              Home Up

From the earliest modules up through the mid-1990's, TSR used module codes which corresponded (usually) to either the modules' theme, setting, or content.  The system eventually got out of hand, and was dropped.  The module codes' commonly accepted definitions are as follows (thanks to Brett Easterbrook, Kent Kelly, and Paul Stormberg for help with this compilation):
