Here's a snippit that will initialize an array and select a number while the array still has elements...what you do with the element is up to you...
use strict;
my $max = 200; #number of elements for
+array
my @array = (0..$max-1); #initialize array
while(@array !=0){
my $index = rand @array; #pick a random element o
+f the existing array
my $element = $array[$index]; #extract the element
my @newarray = grep {$_ !=$element} @array; #remove the element
@array = @newarray; #reset the array
}
Addendum: See BrowserUk's reply for a more tidy/efficient method of extracting the element from the array

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).
