I apologize my question is confusing and that I haven't followed proper update protocol. Please do not interpret my mistakes as a lack of care to post things the proper way on this forum. I changed around the question multiple times in order to attempt to make it more clear, and to try and address the previous answers. The script I posted doesn't compile because I edited all the variable names to try to make them generic and thus clear, and I left one unchanged by mistake.
All I want to do is learn how to use perl to accomplish the same thing done with the unix join command in a bash environment because it would make my life much easier if I didn't have to write a script every time I need to analyze a particular unison between two files. Join works great but I would like to have finer control than it allows.

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.
