Hi all, I have a small script as follows. I wonder how I can change 65 66 67 back to ABC. Thanks, Li C:\Documents and Settings\chen73>irb irb(main):001:0> str="ABC" => "ABC" irb(main):002:0> str.each_byte{|b|puts b} 65 66 67 => "ABC" irb(main):003:0> ____________________________________________________________________________________ Choose the right car based on your needs.
