Greatgrandson (S,X):-man(S), parent(P,S), parent(Y,P), parent(X,Y). Granddaughter (G,X):-woman(G), parent(P,G), parent(X,P). Grandfather (G,X):-man(G), parent(P,X), parent(G,P). Grandmother (G,X):-woman(G), parent(P,X), parent(G,P). Scripts & SDK: SDK: extend processor modules, plugins and loader API to be able to use a C++ class for internal implementation. hexrays: use standard Rename address dialog in pseudocode view to rename global names. Second_coustin_aunt(V,Z):-parent(X,L),parent(X,K),parent(L,N),parent(K,M),parent(N,Q),parent(M,Z),parent(Q,V),parent(Z,C),man(Q),man(C),woman(Z),woman(V),not V=Z. hexrays: support some inlined string/memory operations for wide (16-bit) characters.

Granddaughter(Y,X):-parent(X,Z),parent(Z,Y),woman(Y). Since that time the Prolog Development Center has been developing and improving its compiler.Grandparent(X,Y):-parent(X,Z),parent(Z,Y),not X=Y. The Visual Prolog compiler is a successor of the Turbo Prolog compiler created in 1980s that was the first Prolog compiler.The Browse Facilities supports search for specific entities, 'go to definition' and 'go to declaration'.The Build Facility supports inserting of necessary packages and include directives.The Graphics Editor is a convenient tool for creating, viewing and editing icons, cursors and small bitmaps.

The Toolbar Editor allows to create various kinds of toolbars.The Menu Editor allows to create both pull-down and pop-up menus.The Dialog Editor provides standard controls to design dialogs.The Text Editor supports convenient text editing and browsing to declarations and implementations.Tree representation of modules, include files, and resources in the Project window helps to group project items into packages and thus gives an extra level of abstraction.It might be especially useful in developing of large projects.Visual Prolog Integrated Development Environment (IDE) is designed to make it easy, convenient and fast to develop, test, and modify applications written in Visual Prolog.Graphical Integrated Development Environment (IDE).supports direct calling of Win32 API functions.

based on logical programming with Horn clauses.

With the Commercial Edition you get additional GUI controls, COM support, ODBC support, sockets, HTTP ActiveX Support, etc. The Personal Edition has limited library support compared to the Commercial Edition. There is library support for: file system, console, registry, environment variables and GUI programs. The Personal Edition is for non-commercial usage only. Visual Prolog is a full-featured programming environment with: * Automatic memory management (garbage collection) * Multi-threading (not supported in the Personal Edition) * Logical programming concepts (backtracking, pattern matching) It supports advanced client-server and three-tier solutions is especially well suited for dealing with complex knowledge. The goal of Visual Prolog is to support industrial strength programming of complex knowledge emphasized problems. It counts PDC Prolog and Turbo Prolog as its predecessors. Visual Prolog is a powerful programming language combining best features of logical, functional and object-oriented programming.
