Though I could do this in my function, it would not help as [0],[1], and [2] are all physically meaningful to me. If I use your suggestion, I loose the information that I seek. Unfortunately avoidance is not the best solution in this case, though I agree that if one can avoid problems, they are easily solved! :-) -- RAINMAN "How much does a piece of gum cost Ray?"
