I moved from Turbo Prolog to Arity Prolog, and am fairly happy with it.  Arity
was substantially less expensive than the PC Prolog marketed by Quintus, and
has all of the features you mention in your list.

On the other hand, Arity and as far as I know every other major PC prolog
except Turbo limits you to 64k of stack space.  It's possible to get useful
work done in spite of this, as long as you are willing to use side-effects
(and if you don't need to backtrack through a really large search space).

I keep hoping they'll get embarrassed by this silly limitation and fix it--
in most other respects they have a top-notch product.
