We have version 5.1  ... we haven't built up enough experience with it to
comment on its bugginess or reliability as another poster has done, but at
this early stage I can give three pluses :

1) Good support - They seem to be there on the phone,  quite knowledgeable and
   helpful - it took one call and about  30 seconds for  the support person to
   diagnose and solve  my installation peculiarity ...  we ended up installing
   it on a different PC than  we had originally  expected.  It looks as though
   it will run on about any MS-DOS machine in the spectrum.

2) Good features - perhaps some of them don't work as advertised,  once we get
   around to pushing the system, but if they all do, this is  one great set of
   extensions  to the  Prolog  environment.  It  interfaces very  openly  with
   Fortran,  C,  databases,  and  has internal   options  for C   and database
   applications as well.

3) Good policies - they give educational discounts  and don't copy-protect the
   disks,  which  made conversion to our  3.5" floppy machine much easier than
   with some other programs like DBASE.

One  concern with all  PC prologs  is that once you get  to a hefty task, will
there be unbearable speed or size limitations?  We don't know yet ...
