Introduction

Welcome to the Tcl tutorial. We wrote it with the goal of helping you to learn Tcl. It is aimed at those who have some knowledge of programming, although you certainly don't have to be an expert. The tutorial is intended as a companion to the Tcl manual pages which provide a reference for all Tcl commands.

It is divided into brief sections covering different aspects of the language. Depending on what system you are on, you can always look up the reference documentation for commands that you are curious about. On Unix for example, man while would bring up the man page for the while command.

Each section is accompanied by relevant examples showing you how to put to use the material covered.
