Logic programming is a type of programming paradigm which is largely based on formal logic.

Another author in the magazine that month wrote that the language's nonstandard, more structured syntax as making "source listings much more readable than those of standard Prolog".

While questioning the market demand for the language, Webster concluded that "Turbo Prolog may be as significant a leap in software design as Turbo Pascal represented three years ago", and recommended it to those "at all interested in artificial intelligence, databases, expert systems, or new ways of thinking about programming". He liked the user interface and low price, and reported that two BYU professors stated that it was superior to the Prolog they used at the university. Webster of BYTE praised Turbo Prolog in September 1986, stating that it was the first Borland product to excite him as much as Turbo Pascal did. Stdio::writef("move a disc from % pole to the % pole\n", A, C),īruce F. Move : (unsigned N, pole A, pole B, pole C). Hanoi(N) :- move(N, left, center, right).

The predicate hanoi takes an integer indicating the number of disks as an initial argument.

In the Towers of Hanoi example, the Prolog inference engine figures out how to move a stack of any number of progressively smaller disks, one at a time, from the left pole to the right pole in the described way, by means of a center as transit, so that there's never a bigger disk on top of a smaller disk. Since version 6.0 the language has been fully object-oriented. Version 7.0 introduced parametric polymorphism. Version 7.2 introduced anonymous predicates (a logical pendant to anonymous functions) and namespaces (see also Visual Prolog 7.2 New Features). Version 7.3 introduced generic classes and interfaces (see Generic programming), guarded monitors (see also Visual Prolog 7.3 New Features).

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 10 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.
