Visual Prolog 8.0

If you ever thought of developing your own application, the Prolog Development Center offers you a comprehensive software program that allows you to fully control the details of your project, such as environment, variables, parameters and other settings.
The program is called Visual Prolog, and it's based on the logic programming language Prolog.

After a smooth installation, you face up quite an outdated interface, one that has no other skin themes than the default one, is composed of an upfront menu, with a mixed toolbar option beneath it and a large display window. I must mention that the toolbar icons seem a bit too overcrowded.

Skipping these small graphical inconveniences, Visual Prologue offers some high features.
One of them is an Integrated Development Environment, that is designed to make program's writing in Prolog easier. It is very useful for large projects and it includes a text editor, a menu editor, a graphics editor and many more facilities.

Moreover, Prolog programming language is fully object-oriented, supports direct linkage with C/C++, parametric polymorphism, and has an automatic memory management.

One last aspect, the Visual Prolog compiler can validate predicate mode, perform powerful type checking and resolve cross-references among declarations.

To summarize, Visual Prolog is a complex program, and though it has a forum for discussions and tutorials, it's addressed to experienced users. Therefore, if have an idea and you know how to build it, Visual Prolog offers you all the needed tools to complete your task.
