The reason the conditional is coming out as true is
that it is not parsed the way you think it is:
if ( ($key eq 'ID') or 'TITLE' or 'GENE' or 'CYTOBAND'
or 'LOCUSLINK' or 'CHROMOSOME' or 'SCOUNT')
# ...
}
... is the same thing. The strings 'TITLE',
etc. are considered true by perl.
(update: ... and everyone beats me and gives
better answers. Sigh...)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
