Can someone explain what is happening here? *Main> getTwoChars ab ('a','b') *Main> getTwoChars a ('\n','a')

The code is doing exactly what it says. getTwoChars reads two characters --- *not* a line. So the next character waiting to be read is the newline, which is returned by the next getTwoChars.

This may depend to some extent on the platform, as Unix defaults to a line-oriented input interface (at the OS level) but Windows to character-oriented input.

I can't confirm that. This is true for compiled programs, but when running liftA2 (,) getChar getChar on the GHCi command line, it seems to use NoBuffering. Greets, Ertugrul -- nightmare = unsafePerformIO (getWrongWife >>= sex) http://ertes.de/
