<h2>Definition and Usage</h2>
<p>The open() method opens a stream to collect the output from any
document.write or document.writeln methods.</p>
<p><b>Note:</b> If a document already exists in the
target, it will be cleared. If this method has no arguments, a new window
with about:blank is displayed.</p>
<h2>Syntax</h2>
