Visual Prolog, also formerly known as PDC Prolog and Turbo Prolog, is a strongly typed object-oriented extension of Prolog. 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 can build Microsoft Windows GUI-applications, console applications, DLLs (dynamic link libraries), and CGI-programs. It can also link to COM components and to databases by means of ODBC. Logic languages are traditionally interpreted, but Visual Prolog is compiled. 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. 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. == Brief Release History == Version 7.5 contains http server and LALR(1) parser generator (see also (New Features in Visual Prolog 7.5 )). Version 7.4 can generate 64 bit windows code (see also (New Features in Visual Prolog 7.4 )). Version 7.3 introduced generic classes and interfaces (see Generic programming), guarded monitors (see also (New Features in Visual Prolog 7.3 )). Version 7.2 introduced anonymous predicates (a logical pendant to anonymous functions) and namespaces (see also (New Features in Visual Prolog 7.2 )). Version 7.0 introduced parametric polymorphism. Since version 6.0 the language has been fully object-oriented. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Visual Prolog」の詳細全文を読む スポンサード リンク
