Free Pascal is a 32-bit and 64-bit compiler for various operating systems and processor architectures, including Intel x86, Amd64/x86_64, PowerPC, or Sparc models.

It is compatible with Borland Turbo Pascal 7.0 and Delphi 7 languages, but implements some improvements such as operator overloading.

The Free Pascal development environment interface is the same as before in text mode, similar to that used in Borland’s Turbo Pascal.

Other Free Pascal features include process overloading, register variable loading, code optimizer, assembler data flow level analysis, and global properties.
