GNU Pascal

GNU Pascal 是一个免费开源的 Pascal 编译器，具备如下特点：

• GPC is a 32/64 bit compiler,
• does not have limits like the 64 kB or 640 kB limit known from certain operating systems – even on those systems –,
• runs on all operating systems supported by GNU C, including
  • GNU Hurd,
  • Linux on Intel, AMD64, Sparc, Alpha, S390, and all other supported types of hardware,
  • the BSD family: FreeBSD, NetBSD, OpenBSD,
  • DOS with 32 bits, using DJGPP or EMX,
  • MS-Windows 9x/NT, using CygWin or mingw or MSYS,
  • OS/2 with EMX,
  • Mac OS X,
  • MIPS-SGI-IRIX,
  • Alpha-DEC-OSF,
  • Sparc-Sun-Solaris,
  • HP/UX,

  and more (note: the runtime system only supports ASCII based systems; that includes almost all of today's systems, but a few IBM machines still use EBCDIC; on those, the compiler might run, but the runtime support might need major changes),

• can act as a native or as a cross compiler between all supported systems,
• produces highly optimized code for all these systems,
• is Free Software (Open-Source Software) according to the GNU General Public License,
• is compatible to other GNU languages and tools such as GNU C and the GNU debugger.
