OK.. you really should look at perlre. The regex /CI: x'(\w+)$/ looks for
"CI: x'<one or more word characters><end of line>". The parens around the \w+ capture that to the variable "$1". And that is going to be the code you're looking for. So in my example.. $1 == "503E". And for any line, it's going to equal whatever is between "x'" and the end of the line.
Hope that clairifies things. And also.. read all of perlre. All of this will be much clearer, and you're probably completely rewrite your script as a result of learning what you can do with regular expressions.

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).
