Abstract
Abstract A software system that simulates the appearance and operation of a calculator provides a user interface to graphic waveform data base manipulation software. The calculator includes a plural key calculator pad, with the keys in the pad being associable in the system with different vector operators. It also includes a subwindow area in which the symbolically encoded operands and operators that form the expression to be evaluated are maintained for viewing by the user. The calculator's keys, which may be operated by conventional cursor control means, are labeled with a descriptive legend representing the currently assigned vector operator. A post-fix operand entry protocol resembling that used in conventional scientific calculators is enforced for keypad input, while in-fix notation is used in the subwindow's representation of the expression to be evaluated. The calculator may be used, in conjunction with an interactive simulator, to facilitate the user interface to graphic waveform manipulation software.
