For quantitative data, anyway, or things which can be ordered consistently. It's unclear to me how well this concept maps to other sorts of data. Complex numbers, for example. I think "not equal", at least the way our brains handle it in general, is not equivalent to "less than or greater than". That is, I think the concept "not equal" is less than or greater than the concept "less than or greater than". <wink> -Peter -- http://mail.python.org/mailman/listinfo/python-list
