In general, the tool is an interactive method of controlling the programmed flow of data in computer memory from an input table of rows and columns includes the steps of (1) generating a control grid (the crossbar) of rows and columns on a display monitor, (2) assigning each row of the grid to a respectively different column of the input table, (3) assigning each column of the grid to the role a different function a column of the input table may perform in generation of the output table, (4) inserting marks at selected intersections of rows and columns of the grid to set the functions selected columns of the input table perform in generation of the output table, and (5) controlling generation of the output table from data in respective input table columns selected by marks in accordance with the respective functions assigned to grid columns by the same marks.
