Free Pascal is a multi-dialect, multi-platform Object Pascal compiler. Originally started to replace the retired Turbo Pascal compiler, it now attempts to follow the Delphi dialect still being developed by Embarcadero Technologies. It has compiler modes for Delphi, Turbo Pascal and Mac Pascal. It also has two modes for its own superset dialect: One mode with exceptions, classes and interfaces, and mode one without.

Free Pascal is a multi-dialect, multi-platform Object Pascal compiler. Its main focus are the Delphi and Turbo Pascal dialect, but a substantial Mac Pascal subset and a minor ISO Pascal mode exist as well.

Free Pascal is available for most common architectures and operating systems.
