Visual Prolog 5.x fully runs and supports OS/2 Presentation Manager. VPI Programs
can easily be recompiled to run under OS/2 PM. We can not assure that every VPI program
will look equally under Windows and OS/2, but as far as we know, there are no other
programming tool that gives such a wide portability as Visual Prolog. Visual Prolog under
OS/2 can now be used without buying a C compiler.
New conversion utility can be found in the BIN directory for each platform. It helps in
the conversion Win16 (32) Projects to OS/2 and back. Conversions of the .VPR and .HAM
files to the text representation and back also supported by this utility.
The Professional version of Visual Prolog 5.x and Visual Prolog 5.1 contain a command-line compiler so it is
possible to create command-line textmode utilities to run under SCO UNIX and LINUX.
At the moment we does not supply VPI or support direct binding from Visual Prolog to
any standard GUI functions under UNIX platforms. Therefore, it is possible to use Visual
Prolog under UNIX only in cases when GUI is not necessary, for example, CGI applications.
There exist some more restrictions:
