VBA Help
Problem
You'd like more information on Visual Basic for Applications.
Solution
Look in the VBA help guide. Select Help
Further, if you'd like to learn more about programming Excel in general, I can recommend Steven Roman's book Writing Excel Macros with VBA (O'Reilly). Steven's book covers most of the topics summarized in this chapter. He also covers topics I've left out that, while useful for general Excel programming, aren't immediately relevant to the calculations I discuss in this book.
