Virtual Pascal is a free 32-bit Pascal compiler, IDE and debugger for OS/2 and Microsoft Windows, with some limited Linux support. Although it had a wide user base in the late nineties, VP has not evolved significantly for several years, and the owner declared in 2005 that development had ceased. Virtual Pascal was developed by Vitaly Miryanov and later maintained by Allan Mertner. There has been pressure from some users for the compiler source to be made into open-source software.

  • Virtual Pascal is a free 32-bit Pascal compiler, IDE and debugger for OS/2 and Microsoft Windows, with some limited Linux support. Although it had a wide user base in the late nineties, VP has not evolved significantly for several years, and the owner declared in 2005 that development had ceased. Virtual Pascal was developed by Vitaly Miryanov and later maintained by Allan Mertner. There has been pressure from some users for the compiler source to be made into open-source software. This has not been done, the main reasons being: The compiler source is mostly written in Intel assembly and is complex and hard to maintain, adapt and stabilize after change. Part of the run-time library is proprietary to Borland Documentation and help is maintained with expensive proprietary tools There is nobody who fully understands the code. Alan said that some of the deeper areas were no-touch for him (original code by Vitaly) The compiler is compatible with Turbo Pascal, Borland Delphi and Free Pascal, although language- and RTL-compatibility is limited for features introduced after Delphi v2 and FPC 1.0.x. VP was primarily useful for the following purposes: Easily port existing 16-bit Turbo Pascal programs to 32 bits Port existing 16-bit OWL programs to 32-bit Windows Write console (text-mode) programs for several platforms Pascal development using the 32-bit Windows API (the classic development, no COM!) Learn object-oriented programming Significant features of Virtual Pascal include: Text-mode IDE Debugger of VP is built directly into the IDE and is reminiscent of Turbo Debugger Fast compilation Tool-chain written mostly in Intel assembly
