You say a very basic Perl operation " appears very complicated" and then repeat the tactics you've used to get others to do your work -- posting a code sample that's essentially no more than a few lines of boilerplate.
This time, what you're looking for is scarcely more than an extension or adaptation of the advice (and solutions) you've been given previously.
You'll do better to start now to try to solve your own homework(?) or $work(?). Twenty-one posts with little evidence that you've made a serious attempt to think through your own questions is not a good reflection on your desire to learn... which is what PM is largely about.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
