<XMP>NN all   IE all   HTML <4
<XMP>...</XMP>End Tag: Required
 

The XMP element displays its content in a monospace font as a block element, as in computer code listings rendered 80 columns wide. In most browsers, the font size is also reduced from the default size. Browsers observe carriage returns and other whitespace in element content. This element has been long deprecated in HTML and has even been removed from the HTML 4.0 specification. You are encouraged to use the PRE element instead.

 
Example
<XMP>
&lt;SCRIPT LANGUAGE="JavaScript"&gt;
   document.write("Hello, world.")
&lt;/SCRIPT&gt;
</XMP>
