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. end implement hanoi goal console : : init (), hanoi : : hanoi ( 4 ).

move ( N, A, B, C ) :- move ( N - 1, A, C, B ), stdio : : writef ( 'move a disc fromВ % pole to theВ % pole ', A, C ), move ( N - 1, B, A, C ).

class predicates move : ( unsigned N, pole A, pole B, pole C ). clauses hanoi ( N ) :- move ( N, left, center, right ). end class hanoi implement hanoi domains pole = left center right. The predicate hanoi takes an integer indicating the number of disks as an initial argument.Д¬lass hanoi predicates hanoi : ( unsigned N ).

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).
