	I tried sending this letter to you through Netmail but it 
  bounced back.  Sorry for cluttering the newsgroup.

	The computer lab at Case Western Reserve uses SBprolog for the
  CMPS 391 Introduction to Artificial Intelligence course taught
  by Prof. Leon Sterling.  The software is public domain and can
  be ftp'ed from megaron.arizona.edu  The program is INCREDIBLY SLOW 
  when running on our Vax 2000 under Unix.  It hogs 2 Megs of memory 
  right off the bat.  It's debuging pales to Sicstus or Quintus Prolog. 
  Yes it does Prolog -- cuts, not, member and all that stuff, but I could 
  never see it really be used in a serious way.

	I am a BIG fan of prolog!  But SBprolog just doesn't cut it.
  For any real work I use Sicstus or Quintus -- they are superior.
  If you can afford a real Prolog get one.  Remember you get what you 
  pay for -- and SBprolog is free.
  BTW our sp and qp run on Sun 3/60 's which may also account for their
  speed.

	This is only my humble opinion based on my experience as the TA
  of CMPS 391 and my useage of SBprolog.  Verdict: thumbs up for Prolog; 
  thumbs down for SBprolog.
