In addition to what others said, if you really needed

my %mapping = (
  "a" => "1",  "b" =>  "2", "c" =>  "3", "d" >   "4", 
  "e" => "5",  "f" =>  "6", "g" =>  "7", "h" =>  "8", 
  "i" => "9",  "j" => "10", "k" => "11", "l" => "12", 
  "m" => "13", "n" => "14", "0" => "15", "p" => "16", 
  "q" => "17", "r" => "18", "s" => "19", "t" => "20",
  "u" => "21", "v" => "22", "w" => "23", "x" => "24", 
  "y" => "25", "z" => "26"

you could replace it with (untested)

my $new_ch = ( $old_ch - 'a' ) + 1;

my $new_ch = chr( ord( $old_ch ) - 96 );

Perl golfers, and those more confident than me, can reduce itr further.

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.
