Abstract
An improved electronic spreadsheet is provided for applications requiring conditional expression execution behavior. Each cell having an executable expression is cooperative with an implicit conditional execution wrapper. The execution of each cellular expression is implicitly conditioned on the state of an individually assigned logical switch expression. The improved electronic spreadsheet also includes a user interface by which a user can assign logical switch expressions to a cell, or to a range of cells. The improved electronic spreadsheet facilitates the use of spreadsheets for wider range of applications than was possible with conventional electronic spreadsheets.
