OK. Did you really mean to use -s¹ in the
shebang line, or did you mean -w?
There are a lot of regular expressions in your program, but
no comments and every single variable name is composed of a
single character. It looks like it fell out of a 1970s
Fortran/Basic timewarp. The indenting is reasonable. Marks out
of 10: 3 (provisional, based on the assumption that you
meant to run with warnings enabled).
¹From the Perl 5 Pocket Reference:
-s Interprets -xxx on the command line as a switch
and sets the corresponding variable $xxx in the
script to 1. If the switch is of the form -xxx=yyy
the $xxx variable is set to yyy.

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).
