I'm using AAIS Prolog, and I like it.  I'm no Prolog expert, but it seems to
be a righteous Prolog and it is a pretty good Macintosh program.  It includes
a large repertoire of predefined Mac ROM calls, and also a general mechanism
for making any ROM call by using its trap number.

It supports both the Edinburgh syntax and an extended syntax called AAIS
syntax.

It requires a good deal of memory, like a megabyte.  Given that, it runs
fine with MultiFinder, and with both recent and older System files.

The price is right; I forget what it was exactly but it was in the neighbor-
hood of $200.
