Getting Started



No matter what prerequisites you have, it is a good idea to read the tutorials.

The tutorials in the Fundamental Visual Prolog section describe differences between Visual Prolog and traditional Prolog, and introduce a program that is developed in Visual Prolog.

Other tutorials discuss the Visual Prolog Integrated Environment (IDE) and various Visual Prolog language features.

Online Help System

Once you are familiar with the concepts and principles, you also can use reference material from the following sections of the Help system:

  • The Language Reference that describes the syntax and semantics of the Visual Prolog language.
  • Integrated Development Environment (IDE) Help.
  • Prolog Foundation Classes (PFC) reference documentation.

This Help is reference material rather than tutorial, meaning that it is not a good place to learn Visual Prolog, but it is a very good place to seek answers to specific questions.

The Help system is available from the Integrated Development Environment.

Discussion forum

You are also welcome to join Visual Prolog discussion forum and seek assistance or share your knowledge in the Visual Prolog Discussion forums.

You will find a lot of interesting information in the Visual Prolog Tips, How To's, Code Samples, etc. And, of course, you are also invited to contribute your own tips, etc.


In the distribution there is a number of example programs. You can install these examples from the IDE, just press Help -> Install Examples.... You can install these examples again and again, so do not worry about experimenting with them.


Visual Prolog is made by the company PDC. We invite you to visit the PDC homepage to find descriptions of real-world commercial projects written entirely in Visual Prolog for:

  • Staff Planning
