What is the .VPH File Extension?

.VPH File Extension Description:

The VPH file extension identifies help files of Virtual Pascal, a 32-bit Pascal compiler for OS/2 and Win32 platforms. It also supports the language of the Borland Pascal and the extensions of the Object Pascal coming from Borland Delphi.

Virtual Pascal compiles most of the existing applications without any need for code changes, enabling you to port existing applications to the 32-bit world of OS/2 in an instant. It is remarkably easy to use, and generates very fast. It can also compact executable files with 32-bits and can completely exploit the IBM's OS/2's powers.

Virtual Pascal has a Run-Time Library (RTL) that includes a special unit called the VpSysLow, which encapsulates and implements all platform dependent calls. The entire RTL is documented using the built-in help system stored in files with the .vph file extension. These files include documentation for all units in the RTL, except for Windows API calls.

Files with the .vph file extension as well as files with the .inf file extension document the base API of OS/2. These files include installation instructions, IDE usage, Pascal language reference, etc. They have been revised significantly and are included in two compressed PDF files with about 1.5MB in size. They also have the ASCII text only version, which is about 300Kb in size. The documentation for the Win32 API is not included in files with the .vph file extension since the API can be obtained from several other sources and is very large in size.

Several utility programs are included with Virtual Pascal in order to create files with the .vph file extension. One of these is the Virtual Pascal Help Generator called "HG" that allows you to generate your own online help files. The other one is called Tph2Vph that automatically converts Borland Pascal help files to files with the .vph file extension.
