Introduction to newLISP

Welcome to this introduction to newLISP! You'll find newLISP easy to learn and powerful, combining some of the power and elegance of classic LISP with the facilities of a modern scripting language, such as regular expressions, network functions, Unicode support, multitasking, and many others.

This book is a straightforward and simple description of the basics of the language. You should be familiar with using a text editor, and ideally you'll have done a bit of scripting before, but previous programming experience or knowledge of LISP isn't required. I hope it's enough to get you started, and ready to start exploring the real power of newLISP.

I'm writing this on a MacOS X system, but it shouldn't make any difference if you're using Linux, Windows, or one of the many other platforms that newLISP supports. The examples are designed to be run in newLISP version 10.

This is an unofficial documentfor the official and definitive description of newLISP refer to the excellent reference manual that is installed with the software.
