|| PMPro Prolog
|| 1.03 (1998)
|| Gregory Bourassa
Simple interpreted Prolog
implementation introduced in 1998 whose unique selling point was the use of a Presentation Manager
interface alongside drag'n'drop and multimedia interface capabilities, in addition to the fairly low cost of 50 USD. There was talk of making available a version that enabled the user to distribute their applications via a re-distributable DLL, but that functionality never surfaced, possibly since PMPro was designed in Visual Prolog
that doesn't support DLL creation.
