I think it would be helpful if you gave us a little context -- checking the value of it's contents seems like just one piece of a multi-step process.
I also tend to get suspicious when I see lots of things with names like "stepxxx" where "xxx" seems to be counting. When one has something like that, I, for one, wonder why isn't an array being used: Why doesn't your structure look like
$hash{opt}{step} = 001, 002, .....999;
This way, you could easily pull out element xxx and test its value.

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).
