A centralized view and management of stored variables for calculators and pieces of software emulating calculators is provided. Users can glance at the status bar and know what variables are stored. A single click then brings up a window within which a list of the stored variables and their values is shown. In this window users can clear individual variables or the entire variable list. Users can be reminded that their calculations contain stored variables by displaying the stored variable names in one or more different colors so that errors can be easily detected and corrected.
