ADL successor
Way back in 1987, Tim Brengle and I created Adventure Definition Language and released the source code to Usenet. A small community has followed it over the years, and I even designed and implemented a successor language in the late 1990s, OADL. Recently, there has been renewed interest in ADL, so I thought I would post the documentation for OADL. You can find it here . Unfortunately, I don't have time to support it, so I won't be posting the source code to OADL for now. Maybe someday... Edit - here is the source to a program written in OADL for your entertainment - 99 bottles of beer .
