The INDIRECT function can be used to generate the formulas. However, in
theory, the INDIRECT function can only retrieve values from an open
workbook. I once downloaded an add-in from somewhere that had an
updated INDIRECT function that claimed to be able to retrieve data from
open and closed workbooks, but I don't remember where I got it from.
