Just in case it's not intentional: You'll lose every 80th character as python intervals do not include the upper bound. The same problem affects the for loop -- e. g. when output[0] has less than COLUMNS columns nothing is printed: >>> range(0, 79/80) [] Peter -- http://mail.python.org/mailman/listinfo/python-list
