Visual prolog
Version 7.3 introduced generic classes and interfaces (see Generic programming), guarded monitors (see also Visual Prolog 7.3 New Features).
Visual prolog 64 Bit#
Version 7.4 can generate 64 bit windows code (see also Visual Prolog 7.4 New Features). Version 7.5 contains http server and LALR(1) parser generator (see also Visual Prolog 7.5 New Features).

Version 8 introduces presenters, for more user friendly data presentation in debugger and running program (see also Visual Prolog 8 New Features). Version 9 introduces bounded polymorphism, extension predicates, threadsafe lock free fact databases, named parameters (see also Visual Prolog 9 New Features). Version 10 introduces object expressions, support for master/slave processes, Microsoft Edge webView2 control and some support for Direct2D+DirectWrite+Windows Imaging Component (see also Visual Prolog 9 New Features). The core of Visual Prolog are Horn clauses, algebraic datatypes, pattern matching and controlled non-determinism like in traditional Prolog, but unlike traditional Prolog, Visual Prolog has always been strongly and statically typed. This provides the important improvement of converting traditional Prolog-typical run-time errors to compiler warnings, which ensures a better robustness of the finished applications. Logic languages are traditionally interpreted, but Visual Prolog is compiled.

It can also link to COM components and to databases by means of ODBC. Visual Prolog can build Microsoft Windows GUI-applications, console applications, DLLs (dynamic link libraries), and CGI-programs. As Turbo Prolog, it was marketed by Borland but it is now developed and marketed by the Danish firm Prolog Development Center (PDC) that originally developed it. Visual Prolog, formerly known as PDC Prolog and Turbo Prolog, is a strongly typed object-oriented extension of Prolog.
