The order that things are returned by keys(), values(), or list-context %hash is not sorted in any particular way, and depends on how things happen to be stored in the hash. There are Tie modules on CPAN that will enable you to always get things back in a particular sorted order, or in insertion order, but only at the cost of slowing down all accesses to the hash. Usually if you want some particular order, you sort the returned keys:
for $key (sort {$a <=> $b} keys %sortListArr) ...
or
for $key (sort {$sortListArr{$a} cmp $sortListArr{$b}}
keys %sortListArr) ...

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).
