the addition of "Sheet" just means that you can work from multiple pages, but the nature of the thing is basically the same..
some time ago, I ran up an Excel prog to do my business accounts, and the "Sheet" instruction
featured quite often, to transfer data to and fro from the Capital and Accounting modules..
it's useful when you want to do a projection
you can update a single entry and see what the effects are..
great for passing data to a graph, etc..
