CountZero

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

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/;` [download]	[reply] [d/l]

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" Oha	[reply]
