I'm looking for a good public domain prolog for use in teaching my AI class. Currently, we're using PD-Prolog which is not sufficient for this class due to its lack of many basic features (like tracing!). What I need is the following: a. Run under MS/DOS b. Follow Clocksin/Mellish syntax, more or less c. Have a sufficient feature set to be able to do some interesting projects d. Be cheap or free, so that the students can afford it. e. Be free of large bugs. There must be some out there, so please give me a call or send me e-mail if you know of one. Thanks for any help, --Kim Tracy, AT&T Bell Laboratories and Illinois Institute of Technology ...att!ihlpa!tracy (708) 979-4164

ALS Prolog is not free or PD, but the "personal" version for the PC is pretty cheap. (If I remember correctly my copy was about AUS$140.) > > yes a. Run under MS/DOS > > yes b.

A student came across one case where it silently failed to compile a clause that was rather complex, but since listing/1 works on compiled code in ALS Prolog you can check that. The way they integrate grammar rules into the system is in my opinion a design mistake, but it does work as documented. > BORALND HAS DISCONTINUED TURBO PROLOG!!!!!!!!!!!!! > Is that shocking or what?????????????? It's the best thing that's happened to the Prolog market for a long time. However, "PDC Prolog" is still on the market, it's no longer Borland that sell it. Let me put it this way: the Turbo Prolog environment has more windows, but ALS Prolog is less "pane". -- I am not now and never have been a member of Mensa. -- Ariadne.

Otherwise, it is a fine product for a small money. > >> BORALND HAS DISCONTINUED TURBO PROLOG!!!!!!!!!!!!! > >It's the best thing that's happened to the Prolog market for a long time. > I totally agree. I hope everyone else does, too. PS. Does anyone know if there is a later version of ALS (>1.2) available?
