PDC's Visual Prolog

(Visual Prolog is the successor of Turbo Prolog and PDC Prolog. The latest version is Visual Prolog 5.2)

  • Visual Prolog Professional 5.2 (ex. books) US$ 699
  • Visual Prolog Printed Handbooks. US$ 69
  • Educational Discounts

Visual Prolog Professional 5.2 (ex. books) US$ 350

On the Visual Prolog Books there is a 20% discount

 

 

 

  • Supported platforms:

  1. DOS
  2. Windows 3.x
  3. Windows 95 / 98
  4. Windows NT/2000
  5. OS/2 2.x and above
  6. SCO UNIX (Text-mode, command-line, CGI Scripts)
  7. Linux (Text-mode, command-line, CGI Scripts)

Includes a complete visual cross-development system for all 16 & 32 bit windows platforms plus 32-bit OS/2

 

  • Disk space required:

The Professional version including all examples, documentation and VDE source code may need more than 100 MB

  • Recommended machine configuration

Visual Prolog can run on a 66 MHz DX2 with 8 MB RAM. For good performance while developing 16 MB RAM and a DX4 100 MHz processor is recommended.

 

  • Backward Compatibility:

Visual Prolog is compatible with old PDC Prolog / Turbo Prolog DOS projects

  • Feature frame or rule-based systems, forward or backward chaining, pattern-matching systems, and constraint-resolution systems.
  • Strongly typed and compiled
  • Predicate mode checking
  • Declarative language. This means that given the necessary facts and rules, Prolog will use deductive reasoning to solve programming problems.
  • Contains four code experts: an application expert, a window expert, a dialog expert, and a toolbar expert.
  • Internet Support:

Internet support for sockets, FTP, HTTP, CGI scripts etc facilitate the development of intelligent web sites

  • Created expert systems can be attached to homepages.

 

  • Allows for graphical editing of dialogs, menus, toolbars, and more.
  • Includes tools to parse and generate HTML, IPF & RTF
  • Includes debugger for 32-bit applications.
  • Include support for project sharing and source code control
  • Includes new linker means programs can be built without the use of a C compiler.
  • Has predicates to trap run-time errors and exceptions as well as to maintain complete control over and detection of user-generated exceptions.
  • Contains tool to create installation programs for applications.
  • Very well suited for expert systems and similar AI applications.
  • Automatic backtracking mechanism helps in finding solutions through backtracking where all combinations are tried
  • Secure and homogeneous decision making
  • Few operating system-specific facilities and limitations
  • Can generate programs for a variety of platforms.
  • Powerful GUI-builder. VPI (visual programming interface) layer makes it possible to create portable GUI applications.
  • The high level of abstraction, and the ease and simplicity with which complex data structures are represented, allow a declarative approach to programming that benefits any discipline or problem solving strategy.
  • Has a full, very easy-to-use database engine.
  • Supplied with lots of tools and support for databases (ODBC, SQL, OCI and DB2).
  • Fast and easy information retrieval
  • Supports Internet development, which makes it an ideal tool for mixing Expert Systems and Java on the web
  • Visual Prolog, applications can be attached to the web. This gives possibility to use Visual Prolog programs through browsers.
  • Is a powerful platform for building Client-Server applications.
  • Well interfaced with others languages. The Object Oriented languages like Java, Visual Basic, Visual C++ and Delphi etc can use objects defined in Visual Prolog.
  • Visual Prolog DLL’s can be use from other languages like Borland Delphi, Java (Microsoft and Sun), Microsoft Visual Basic and Microsoft Visual C++ etc.

 

  • Possible to create and use pre-compiled libraries.
  • Short Development Time
  • Fast speed of compilation and linking
  • Code easier to modify, when aspects of the domain in question change.
  • Ongoing maintenance costs often lower.
  • Easy to Read.
  • Easy to learn.
  • Easy Manipulation of Complex Data Structures like trees, lists or graphs.
  • Highly optimizing compiler
  • User friendly
  • Provides an extra level of security in programming.
  • Support only the Intel platform i.e. runs on x86 machines only
  • Visual Prolog costs money
  • Visual Prolog does not include source code
  • Oriented towards exploratory programming
  • Visual Prolog is compiled language, one cannot write programs that create new clauses as they run (i.e. programs that write themselves).
  • The debugger is not for Win16 platforms.
  • Does not support multithreading.
