I think they should come out to meaning the same thing, though the [0][0] form may be less efficient if it has to temporarily construct a slice of the next dimension of the array. On the other hand, a naïve implementation of the multidimensional subscripter might just do the same thing internally for the semicolon, so it could be a wash. Larry
