<pre wrap="">If you want to start writing code, I recommend you start by reading the
TeXbook. It is the de-facto standard of the TeX macro language:

If you don't want to spend money, I've also heard good things about TeX
by Topic, which is free to read. However, this has more of a reference
manual character:

David Salomon's <i>The Advanced TeXbook </i>is also worthy of
consideration, as is Stephan von Bechtolsheim's magnificent 4-volume
<i>TeX in Practice.<br>
