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 compatibility mode is also provided to assist Apple users. Furthermore Free Pascal supports function overloading, operator overloading, global properties and other such features.

Requirements:

x86 architecture:
For the 80x86 version at least a 386 processor is required, but a 486 is recommended.

PowerPC architecture:
Any PowerPC processor will do. 16 MB of RAM is required. The Mac OS classic version is expected to work System 7.5.3 and later. The Mac OS X version requires Mac OS X 10.1 or later, with the developer tools installed. On other operating systems Free Pascal runs on any system that can run the operating system.

ARM architecture:
Only cross-compiling to ARM is supported at this time.

Sparc architecture:
16 MB of RAM is required. Runs on any Sparc Linux installation.
