Two ways:
c:\@Work\Perl\monks>perl -wMstrict -MData::Dumper -le
"my $aref = [
[ 'kept', 82 ],
[ 'notkept', 1 ],
[ 'repaired', 3 ],
];
print Dumper $aref;
;;
for my $i (0 .. $#$aref) {
printf qq{label $aref->[$i][0] };
}
print qq{\n ---------};
;;
for my $aref_2nd_level (@$aref) {
printf qq{label $aref_2nd_level->[0] };
}
"
$VAR1 = [
[
'kept',
82
],
[
'notkept',
1
],
[
'repaired',
3
]
];
label kept label notkept label repaired
---------
label kept label notkept label repaired

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
are good places to start.
