Weird... I never knew this, although I had noticed-in-passing that hitting ^Z to exit the interpreter didn't always work as intended. Nice to have an explanation why. On a related note though: EOF _is_ recognized in mid-line if you are just reading from a file (in text mode, obviously, not binary mode). I wonder what freakish design decisions led to that situation... -Peter -- http://mail.python.org/mailman/listinfo/python-list
