Hi Brandon, I am writing up what you just said for my keepers file. Would you please define for me what you mean by the following: 1) expressions 2) the difference between "expressions" and "general expressions" 3) Quoting. The difference between "" and <> 4) "interpolating" as it refers to Perl (not math, where you "guess" what a value is based on values on both sides of you). Many thanks, -T Did a bad interpolation on a matrix once and the bad formula turned out to be a sine wave which really messing up interpolating based on it. Chuckle! Always a good idea to graph your formula before using it to guess values! -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Computers are like air conditioners.
