Abstract
Abstract An operator prompting system for a calculator of the type having stored program control for performing a limited number of pre-programmed calculations, the prompting system being adapted to guide an operator through the different programs by directly indicating the need for a data entry and the nature of such entry. In a preferred embodiment, the calculator display is of the alpha-numeric variety, and means are provided for driving the display to directly indicate upon such display the nature of the data required. The program module within the calculator may be configured to carry out complex calculations in various specialized fields, such as navigational, financial, scientific or engineering, the alpha-numeric display being used to display the numerical data as entered and the results, and also to directly call for the data required for the different programs or uses.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
231 words
In a self-contained electronic computer for mathematical problems having: a housing including a plurality of data input keys, a plurality of program selector keys, a visual numerical display, calculator means for performing mathematical operations, a stored program controller, said controller having a plurality of programs stored therein for solving a plurality of mathematical problems, each of said programs comprising a routine of program steps, means coupling the controller to the calculator means for causing said calculator to perform the mathematical operations indicated by said program steps, at least some of said program steps requiring the manual entry of data during the course of the program via the data input keys of said keyboard, means coupling said program selector keys to said controller for selecting associated ones of the programs stored in said controller, an operator prompting system comprising means for visually indicating in conversational language with data titles the individual types of data to be entered during said programs, and means for driving said indicating means and operative in conjunction with said program steps requiring manual entry of data for displaying selected ones of said data entry titles to prompt the operator as to the type of data required by said program steps, whereby selection of a program is effective to cause said computer to demand the necessary input data in sequence and manipulate said data to calculate the desired results.
