Date: 10 Dec 1982 1449-PST From: PEREIRA at SRI-AI Subject: [PEREIRA at SRI-AI: Re: Prolog] To: bts.unc at UDEL-RELAY Some of the infomation on the following message might be useful for the prolog newsgroup. --------------- CProlog is a system for serious work, and is relatively well developed. I am continuing to improve and debug it here at SRI. For legal reasons, I cannot distribute the system, except to people that have already a license from Edinburgh. I don't have the time to send copies of my improved version of the system to other people on a regular basis, but I will be glad to answer any specific queries and gripes. CProlog was designed to run on large address space machines, and so it would be very difficult to port it to the Onyx machine, as it gives only 128k bytes per process. However, there is another Prolog in C that will run on a Z8000, UNSW Prolog from Claude Sammut Dept. of Math and Computer Science Saint Joseph's University 5600 City Avenue Philadelphia PA 19131 That system has also a number of nice features in its interface with Unix, that CProlog lacks (on the other hand, CProlog has floating point numbers and some powerful database features that other Prologs don't have). Overall, the two systems are very nearly compatible. Although there are network connections with Edinburgh from the US, it is two painful to send large files through them (I have given up ...). However, the mail connections are reasonably good: some machines in the UK are on USENET, and there is also an Arpanet gateway that allows mail between various nets in the UK and the US. Prolog is being used at many universities and companies in the US. Here is a sample: Syracuse, Kentucky, Stanford, Caltech, Rochester, Duke, New Hampshire, North Carolina, Yale; SRI, DEC, IBM, HP.
