This could probably be refactored more elegantly, but it seems to do the job in a single pass without undue complexity.
use strict;
use warnings;
my @values = qw( 5 3 2 12 2 );
my @names = qw( Cat Bat Cow Dog Rat );
my $min;
my @indices;
foreach my $ix ( 0 .. $#values ) {
if( ! defined $min or $values[$ix] < $min ) {
@indices = ($ix);
$min = $values[$ix];
}
elsif( $min == $values[$ix] ) {
push @indices, $ix;
}
}
print "Lowest value: $min\n";
print "$_ => $names[$_]\n" for @indices;

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).

or How to display code and escape characters
