Visual Prolog is the complete programming environment based on the Prolog programming language. It contains everything needed for building large-scale commercial applications: Integrated Development Environment (IDE), compiler, linker, debugger, on-line Help, and Visual Prolog Foundation Classes (PFC). PFC is the collection of classes and interfaces that constitutes the foundation for writing various kinds of applications and software components. The classes and interfaces are organized in the package hierarchy. PFC supports: GUI, file system, fact databases, external databases, arithmetic, string handling, date and time, ODBC, registry, CGI, sockets/HTTP/FTP, Microsoft COM, multi-Threading, etc.

bin Contains executables and some supplementary files for Visual Prolog.
bin64 Contains executables and some supplementary files for Visual Prolog 64bit platforms.
dll Contains Visual Prolog runtime DLLs for 32bit targets.
dll64 Contains Visual Prolog runtime DLLs for 64bit targets.
icons Contains some freeware/shareware icons please read the license conditions in the directories
lib Contains the Visual Prolog libraries for 32bit targets.
lib64 Contains the Visual Prolog libraries for 64bit targets
pfc Contains the Visual Prolog Foundation Classes (PFC).
vip Contains the packages for dealing with the Visual Prolog system itself. In particular it contains the Visual Prolog parser (see vip\vipParser and vip\vipSyntax).
