    Anyone know of a way of view the carriage returns of a text file? i.e. to determine if it has a unix style line break or a DOS one? Thanks

    Well I was thinking of an application rather than any particular language. Something that would allow me to see the (ASCII?) actual characters.

    Most decent editors will tell you this, I think - I know that both UltraEdit and jEdit put this in their status bars. Otherwise, assuming you're using something more sophisticated than notepad, the following guide may be useful:

    \r\n (i.e. ASCII 13/xD, ASCII 10/xA, or CR, LF) means DOS/Windows;
    \n (i.e. ASCII 10/xA, LF) indicates Unix (and possibly Mac OS X, not certain)
    \r (i.e. ASCII 13/xD, CR) on its own indicates Mac (at least, System 9 and earlier)

    CR = Carriage Return
    LF = Line Feed

    (a hangover from the old days of teletypes, this stuff)

    Hope this helps,
    Gadget
