1. A method, executed in a computer system, of implementing a sum function in an application program under the operation of a user during a user session, where the application program uses a worksheet to store and manipulate data, where the worksheet comprises a two dimensional grid of intersecting columns and rows, where the intersection of each column and row is a cell, where a cell may contain data, and where a plurality of cells is a contiguous range of cells in the same column or row, the method comprising the steps of:

  • (a) during a user session, choosing a cell within the worksheet where a sum result will be displayed, the chosen cell having a location in the worksheet,(b) during the user session, requesting execution of the sum function;

    (c) in response to steps (a) and (b), the computer system automatically determining during the user session, which of a plurality of cells to select based upon the location of the chosen cell in the worksheet and without prior programming or input by a user to explicitly select the plurality of cells; and

    (d) responsive to the execution request, calculating the sum result of data associated with the determined plurality of cells and displaying the sum result in the chosen cell.
