Free Pascal is a mature, universal, open-source Pascal compiler. It can run on many processor architectures. Supported operating systems include Windows 64-bit. Free Pascal (full name Free Pascal Compiler, often abbreviated to FPC) is a freely distributed compiler of the Object Pascal programming language.

Alternatives

Main features: writing, compiling, and debugging programs written in Pascal, comes with a runtime library and a Freepascal component library, provide global properties, function overloading, and operator overloading, and offers an active user community. The language syntax is perfectly compatible with TP 7.0 and with most versions of Delphi (classes, RTTI, exceptions, ANSI strings, sweeping strings, interfaces). A Windows 64-bit Pascal mode is also available, largely compatible with Think Pascal and Metrowerks Pascal. In addition, Free Pascal supports function overloading, operator overloading, global properties, and some other advanced features. The project is also currently developing Lazarus, a free development environment analog of Delphi, and Lazarus Components Library (LCL), a free widget library similar to Delphi's VCL.

Why download Free Pascal to Windows 64-bit?

It works very fast on this device. You will be delighted when you get this app. It is compatible with the Borland Turbo Pascal 7.0 and Delphi 7 language supports, although it has better improvements for them, such as the over boarding operator. The Free Pascal environment's interface is in text mode, as before, and is also similar to that of Turbo Pascal and Borland. Other features of Free Pascal are processing overhead, register loading variables, code optimizer, flow level analysis data assembler, global properties, and so on. Links to some older versions (no longer supported) of FPC for platforms for which no better alternative currently exists can be found here. Do not try to report any bugs in these older releases - we will not fix them. The main reason these platforms are no longer supported is the lack of maintainers - if you are interested in upgrading these platforms, contact us.
