My CODE did take into account <end-of-line> inside.
and I don't plan to spend the time to create a HTML reader.
< and > will show if the character following < is not a letter
or an (!) exclamation point.

The proper way to show < is with &lt; and > with &gt; meaning
LessThan and GreaterThan. You are suppose to follow &lt with
the semicolon. To show & you are suppose to use &amp which
means Ampersand.

<dummy> and <I have created a dummy >
<! This is a HTML comment>

This is an Euphoria list it should not have turned into a HTML
lesson.

I and my Parsing accomplice where trying to show how Parsing
would be handled.  We had no intentions in creating a full blown
parser for HTML files.  (well at least I didn't :] )

But of course Reaper is right.  We should have mentioned that
we had not handled all the details of HTML.

My apologizes for not making that clear.
