in reply to Problem printing @arrays

I suspect you are reading a file created with \r\n (carriagereturn-linefeed) line endings (e.g., on a Windows system) on a system (e.g., *nix) that uses \n (linefeed) line endings. On the reading system, the line-feed is chomp-ed off leaving the carriage-return. This can be simulated with something like:

    I'll have to study this a little more. The dd command isn't what I would call intuitive. I'm sure, though, that I'll learn something by it I cannot learn any other way; much like holding a cat by the tail :)
