A script that scrolls the contents of a textarea automatically.

<script language="javascript" type="text/javascript">

<!-- HTML comment to placate non JavaScript capable browsers
/* Typing Text Area Page Scroller
This script was created to provide another alternative to those erratic and
hard to read sideways scrolling text and status bar displays.  This script
uses TEXTAREA to create the effect of text scrolling up the page.
