Abstract

A spreadsheet package allows a base formula to be copied to at least one adjacent cell to form a referencing array. The package maintains a list of bound arrays, at least one cell of a bound array being referred to from a referencing array formula. If a formula within a referencing array cell includes a reference to a cell outside a bound array, the package indicates an error in the formula.
