Although Turbo Prolog has been characterized by some wags as a "brain-dead implementation" I think its mixture of strengths and weaknesses would be more accurately described as those of an idiot savant. Some of the extensions, such as the built-in string editor predicates, are positively serendipitous, and you get most of the development time advantages of a fifth generation language for a conventional application plus good runtime performance for only $70. On the other hand, one tires quickly of writing NP-incomplete sets of type declarations which are unnecessary in any other implementation.... If nothing else, for $70 you can prototype something that can be used to justify spending $700 for a real PC Prolog compiler, or $18,000 for a VAX implementation. John Reece Intel
