in thread searching for strings

Sorry! How strange of Perl to be asymmetric! Why is "--" not as magical as "++"? This will work instead... 
$char_up =~ tr/A-Z0-9/B-ZZ1-99/;
$char_down =~ tr/A-Z0-9/AA-Y00-8/;

    cauz if so it wouldn't be symmetric :)

    suppose you have "A00", if you -- you'll get "99" and then if you ++ you'll get "100"
