Since glob has not been mentioned yet, here's another solution (TIMTOWTDI).
use strict;
use warnings;
my $start = 'zzy0'; #-- start including this 'number'
my $end = 'zzz5'; #-- end including this 'number'
my $set = '{' . join(',', 0..9, 'a'..'z') . '}';
#-- max. range is '0000' .. 'zzzz'
for ( glob "$set$set$set$set" ) {
print $_,"\n" if /$start/ .. /$end/;
}
Caveat: This approach is not efficient. It can consume lots of memory and time (filtering).

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).
