See GotToBTru's post to create a proper example, but from your code, I see this:
# exported functions
That makes me think you copy/pasted something off of the Internet, and with the lines that follow that comment, it appears it closely resembles perl4 code (or someone coding perl5 that hasn't migrated to the perl5 mindset yet. This was nearly two decades ago!).
I feel that you need some new resources to read, research and reflect upon. Is this a project that you were forced into and are trying to adjust by chance?

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).

or How to display code and escape characters
are good places to start.
