With the Commercial Edition you get multi-threading, additional GUI controls, ODBC support, sockets, HTTP and much more. 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. NOTE: The Personal Edition is for non-commercial usage only. Visual Prolog is a very safe and powerful programming language that combines the very best features of functional, logical and object-oriented programming paradigms in a elegant and consistent way. Visual Prolog supports advanced client-server and three-tier solutions and 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. Visual Prolog is a logical programming language that counts PDC Prolog and Turbo Prolog as predecessors.

In some cases, the вЂњinterfaceвЂќ is not required (if we are not going to create class instances), but the other two are must.Top Software Keywords Show more Show less вЂ“ вЂњImplementationвЂќ file that implements the clauses, etc. вЂ“ вЂњClassвЂќ file, that declares the class-specific interface вЂ“ вЂњInterfaceвЂќ file, which defines the interface/behaviour provided by the вЂњobjectsвЂќ of a class

Since Visual Prolog is вЂњobject orientedвЂќ, functionality is implemented in classes, whose code is distributed in three files: In case the integer вЂњkeyвЂќ is not present, it will assign вЂњ-999999вЂќ to the output argument.ДЄs you can see, Visual Prolog supports functions and procedures too, in addition to the regular non-deterministic вЂњHorn ClausesвЂќВ . The DLLВ provides the following:ДЎ) A function called вЂњfactorialвЂќ that takes an integer argument and returns the corresponding factorial of the argument.Дў) A procedure called вЂњlookupвЂќ that takes two arguments: an integer, which acts as a вЂњkeyвЂќ for lookup and and an вЂњoutвЂќ parameter that corresponds to the looked up value. Getting back to our main topic, I decided to create a DLL in Visual Prolog.

In that sense, since Prolog is a declarative language and is good at logical inferencing, we might consider using it to implement an application such as a Medical Diagnosis system that has an Expert System subcomponent.

The capability to use DLLs (in Windows environment) written in one language can come in handy if we want to exploit the languageвЂ™s special features for implementing specific functionalities, even though the main application is written in another language say, Erlang, Go, etc. I do this usually with other languages too, see for example this and this. Instead of writing the canonical вЂњHello, world! вЂњ program, I wanted to start by implementing a DLL that I can call from C/C++. I upgraded to the latest version (ver 10) a couple of weeks ago and decided to spend some time understanding the language and the environment.

There are a couple of PDF books but they cover an older version (ver 7.x or earlier). One reason is that it seems to have a steeper learning curve and there are not many video tutorials to explain the language and the environment. So, if you donвЂ™t need a вЂњStandardвЂќ Prolog, then Visual Prolog has a lot to offer.ДЄlthough I purchased the Commercial Edition of Visual Prolog a few years ago, I never got around to using it. Because of strong typing and compile-only strategy, the efficiency of generated code is likely to be superior compared to other interpreted environments. We can quickly build Console mode or GUI-based applications, DLLs, and even Windows Service using the platform. Visual Prolog is quite rich in functionality. So how is Visual Prolog different from other Prolog implementations out there, for example, SWI-Prolog or Sicstus Prolog?Дў) It is strongly-typed and is object-orientedДЈ) It is a compiled environment, not interpreted Visual Prolog supports advanced client-server and three-tier solutions and is especially well suited for dealing with complex. It is developed and supported by PDC A/S, Denmark. Visual Prolog is a logical programming language that counts PDC Prolog and Turbo Prolog as predecessors. Visual PrologВ has its roots in Turbo Prolog, which was popularized by Borland in the mid 1980s.
