Check out ord and chr. `=item ord EXPR =item ord Returns the numeric ascii value of the first character of EXPR. If EXPR is omitted, uses C<$_>. For the reverse, see L</chr>. =item chr NUMBER =item chr Returns the character represented by that NUMBER in the character set. For example, C<chr(65)> is C<"A"> in ASCII. For the reverse, use L</ord>. If NUMBER is omitted, uses C<$_>.` [download]	[reply] [d/l]

chr

    =item ord EXPR

    =item ord

    Returns the numeric ascii value of the first character of
    EXPR.  If EXPR is omitted, uses C<$_>.  For the reverse,
    see L</chr>.



    =item chr NUMBER

    =item chr

    Returns the character represented by that NUMBER in the 
    character set. For example, C<chr(65)> is C<"A"> in ASCII.
