Syntax: @(S)
S = a string representing a cell or range
@ returns a reference to the cell or range represented by S.
Example:
@(``B17'') = 17, where B17 = 17
SUM(@(``B2..B7'')) = 24, where B2..B7 = 12, 1, 0, 4, and 7
AVG(@(``B2..B7'')) = 4.8, where B2..B7 = 12, 1, 0, 4, and 7.
@(C1) = Error - improper argument type, because C1 must be in quotation marks to be a string.
