Visual Prolog 5.2

Visual Prolog version 5.2 offers many improvements compared to version 5.1. 

You will find serious improvements in the language/compiler and the VDE is now much more convenient.

The build time of large projects has been reduced that, together with the improved handling of domains, can result in a shorter edit/compile/debug cycle.

While creating Visual Prolog 5.2, we paid special attention to its Linux and SCO UNIX versions, because many of Visual Prolog programmers wanted to build their CGI and other console applications on these platforms. Visual Prolog 5.2 supports Red Hat 6.0 Linux.

Below you will find short descriptions of the major new compiler/language and VDE features. 

For a complete list of changes see Changes from Visual Prolog 5.1 to Visual Prolog 5.2.

To evaluate Visual Prolog 5.2, you can download and install the Personal Edition of Visual Prolog 5.2 . Please, read "Upgrade Notes" before installation.

Visual Prolog 5.2 Main Issues.

Improved Domain Handling Strategy

From VIP 5.2 the handling of global domains is improved, so that global domains no longer need to be included in all modules of a program.

 See detailed description.

Improved Class Declaration Handling Strategy

Class declarations no longer have to be included in each module (like global domains). 

Object Predicate Values (new language feature)

See detailed description.

Declaring Domains inside Classes. (new language feature)

See detailed description.

Class System is now Compatible with COM. 

Beginning with VIP 5.2 it is possible to use Visual Prolog classes for implementation of COM interfaces. Abstract class predicates can now have stdcall calling convention.
Please, see example in \VPI\Examples\MsCom.

Faster Rebuilt of Large Projects

Large multi-module projects are rebuilt faster than in previous versions of Visual Prolog.
