Virtual Pascal - Features

Features

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 (in theory)
  • 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 is integrated directly into the IDE and is reminiscent of Turbo Debugger
  • Fast compilation
  • Tool-chain written mostly in Intel assembly

Famous quotes containing the word features:

    “It looks as if
    Some pallid thing had squashed its features flat
    And its eyes shut with overeagerness
    To see what people found so interesting
    In one another, and had gone to sleep
    Of its own stupid lack of understanding,
    Or broken its white neck of mushroom stuff
    Short off, and died against the windowpane.”
    Robert Frost (1874–1963)

    Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.
    Henry David Thoreau (1817–1862)

    These, then, will be some of the features of democracy ... it will be, in all likelihood, an agreeable, lawless, particolored commonwealth, dealing with all alike on a footing of equality, whether they be really equal or not.
    Plato (c. 427–347 B.C.)
