I certainly wasn't trying to correct you, DAB. Just trying to throw in a fun fact. Any linear ordering of data for which we can perform comparison operations on the indices, so long as they are unique…

No problem, I was just making sure that we answered the question of an obvious newbie with simple explanations. There is plenty of time to bring them over to the dark side later. DAB
