You use arrays whenever you have a set of data that you want to work with as a unit—lists and tables are typical examples of when to use an array.

To prove that the stored prices are numbers, I calculate the tax on each price before displaying the table in the Immediate window:
Sub ShowVariantArray( ) Const RATE = 0.06 Dim PriceChart(4, 1) As Variant PriceChart(0, 0) = "Grudgeon" PriceChart(0, 1) = 24.95@ PriceChart(1, 0) = "Pintle" PriceChart(1, 1) = 11.15@ PriceChart(2, 0) = "Tiller" PriceChart(2, 1) = 93.75@ PriceChart(3, 0) = "Rudder" PriceChart(3, 1) = 42.49@ Dim i As ...
