I have a copy of the source for UNSW prolog that I have spent a lot of time hacking. Anyway, I've modified it so that it uses the same syntax as C Prolog, plus added a few of the "niceties" to it. The one thing I am lacking is the code for the 'retract' clause. I am willing to hack this in, but I was curious if anyone else had already done this. After I have completed this, I will post my diffs to whatever bulletin board is considered appropriate, and I will make the source available via anonymous UUCP from my home system. Thank you for your help. Thomas V. Frauenhofer ...!rutgers!rochester!cci632!ccird7!tvf *or* ...!rochester!kodak!swamps!frau!tvf *or* ...!attctc!swamps!frau!tvf "The Earth? I'm going to blow it up.
