JS, thanks a lot for your suggestion to use Sum().
It never occurred to me to use it in this way. The example of
computing a moving average in the user manual made it look like a not very
useful function. Now I see that both sum and cum will allow me to do
very precise and extensive lookbacks at previous arrays. Ron D

still have not been able to grasp doing loops. If looping is a good
way to do this, I would sure appreciate seeing the below IIF coding made
into a looping function. Then, by knowing what it is designed to do,
I should be able to finally understand how looping works. Ron
