### 4.1.1 What and why?

The purpose of the GNU Pascal project is to produce a Pascal compiler (called GNU Pascal or GPC) which

- combines the clarity of Pascal with powerful tools suitable for real-life programming,

- supports both the Pascal standard and the Extended Pascal standard as defined by ISO, ANSI and IEEE (ISO 7185:1990, ISO/IEC 10206:1991, ANSI/IEEE 770X3.160-1989),

- supports other Pascal standards (UCSD Pascal, Borland Pascal, parts of Borland Delphi and Pascal-SC) in so far as this serves the goal of clarity and usability,

- may be distributed under GNU license conditions, and

- can generate code for and run on any computer for which the GNU C compiler can generate code and run on.

Pascal was originally designed for teaching. GNU Pascal provides a smooth way to proceed to challenging programming tasks without learning a completely different language.

The current release implements Standard Pascal (ISO 7185, levels 0 and 1), a large subset of Extended Pascal (ISO 10206, aiming for full compliance), is highly compatible to Borland Pascal (version 7.0) with some Delphi extensions, and provides a lot of useful GNU extensions.
