What is Free Pascal ?

Free Pascal is a compiler for 32-bit and 64-bit CPU architectures such
as Intel 32/64 bit, AMD 32/64 bit, SPARC, PowerPC and Intel ARM. It
is language compatible to Turbo Pascal, Delphi (till version 7), and
partly Metrowerks Pascal. It supports many operating systems: Dos,
Linux, Windows, OS/2, FreeBSD, NetBSD and OpenBSD, Novell Netware, Mac
