Yes, but there is one other thing: My arrays are two-dimensional, based on a
row and column structure, like a range. If I use ReDim Preserve to increase
the big array to add the non-duplicate elements, I can only increase the last
dimension of the array. Since I'm adding rows in effect, I guess I would
need the array structure to be Array(column, row) instead of Array(row,
column). Right?

dunno :)

What kind of values have you got in the inner array? could you
consolidate them to a string using Join method - for the time of
comparation, and array redimensioning, and then do a loop throughout
the array to split them back? It's just a loose idea, as I'd prefere to
see the example itself
