Another approach using array slices.

c:\@Work\Perl\monks>perl -wMstrict -MData::Dump -le
"my @AoA = (
   [ '00' .. '09' ],
   [ '10' .. '19' ],
   [ '20' .. '29' ],
   [ '30' .. '39' ],
   );
 dd \@AoA;
 ;;
 print join '-', @{ $AoA[1] }[ 3 .. 7 ];
 print qq{@{ $AoA[2] }[ 2 .. 5 ]};
"
[
  ["00", "01", "02", "03", "04", "05", "06", "07", "08", "09"],
  [10, 11, 12, 13, 14, 15, 16, 17, 18, 19],
  [20, 21, 22, 23, 24, 25, 26, 27, 28, 29],
  [30, 31, 32, 33, 34, 35, 36, 37, 38, 39],
]

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
