History
The compiler was quite popular in the BBS scene, probably because of its OS/2 port and being one of the few affordable multi-target compilers. Also Turbo Pascal had been popular in the BBS scene too, but its successor, Delphi was suddenly for Windows only. Virtual Pascal provided a migration path for existing codebases.
There has been pressure from some users for Virtual Pascal to be made into open-source software. This has not been done, provided the following reasoning:
- The compiler source is mostly written in Intel assembly which is hard to change and maintain.
- Part of the run-time library is proprietary to Borland
- Documentation and help are 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)

Famous quotes containing the word history:
“The history of mankind interests us only as it exhibits a steady gain of truth and right, in the incessant conflict which it records between the material and the moral nature.”
—Ralph Waldo Emerson (1803–1882)
“In the history of the United States, there is no continuity at all. You can cut through it anywhere and nothing on this side of the cut has anything to do with anything on the other side.”
—Henry Brooks Adams (1838–1918)
“The best history is but like the art of Rembrandt; it casts a vivid light on certain selected causes, on those which were best and greatest; it leaves all the rest in shadow and unseen.”
—Walter Bagehot (1826–1877)
