Free Pascal

Free Pascal is an open-source, cross-platform, and highly compatible Pascal compiler and integrated development environment (IDE). It was originally developed in 1993 and has since evolved into a mature and powerful tool for developers.

Pascal is a versatile programming language known for its simplicity, readability, and strong typing system.

Free Pascal 64bit extends these advantages by providing a modern IDE and robust compiler, making it an ideal choice for developing applications across multiple platforms.

The language syntax has excellent compatibility with TP 7.0 as well as with most versions of Delphi (classes, rtti, exceptions, ansistrings, widestrings, interfaces).

A Mac Pascal mode, largely compatible with Think Pascal and MetroWerks Pascal, is also available. Furthermore Free Pascal 64 bit supports function overloading, operator overloading, global properties, and several other extra features.
