HyperProlog is actually Delphia Prolog (produced in France and
distributed by Arity).  It is a complete extended C&M implementation,
with additions to allow it to work with HyperCard, with or without
multifinder.  I have just ordered it and will be happy to give a review,
though I expect it will be quite a while before I really test its
capabilities. 

Regarding price - everything is relative, and $395 list is not
cheap, but it isn't unreasonable.  Look at Quintus - $595 for
the compiler/interpreter/editor and another $495 for the runtime
generator.  I looked for prolog/m, which made a $95 version, but
they don't seem to be in business any more.  If anyone knows
where they are located, please let me know.

The name of HyperProlog is misleading - it is not an add on for
hypercard.  Instead, it is a complete prolog system that has
XCMDs and XFCNs to interface with hypercard.
