| Abstract: |
A user programmable calculator includes a keyboard, output display means and logic circuitry which generates to the output display means a prompting message indication of the type of data or function entry which the system's operative program, which may be a user stored program, next expects. The keyboard includes a special set of response keys in addition to the numerical and function keys normally incorporated on calculator systems. The special keys facilitate responding to data functional information requests by the calculator. The calculator may be programmed by the user to perform a series of functions upon data entries by entering a series of program steps from the keyboard or from a storage media such as magnetic card, paper tape or the like. The program steps which contain the prompting messages are stored in registers of the calculator system. Upon execution of the stored user program, each time data, functional or responsive information is required a coded representation of the particular entry required to proceed is generated by the logic circuitry and displayed to the user by the display means. The required data may then be entered from the keyboard and the program will continue until entry of further data is required from the user, thereby allowing the user to input in proper sequence a long series of inputs to execute a previously programmed operation on a desired set of data without referring to the program itself.

What is claimed is:
1. A programmable calculator having program storage and program execution modes comprising:
- a. a keyboard having function keys and alphanumeric data entry means and a plurality of response keys;
- b. storage means for storing data and user program instructions including prompting messages which indicate specific information required by a user program in order to proceed executing a user program with said calculator in said program execution mode;
- c. means selectively coupling said keyboard to said storage means for transferring data and user program instructions including prompting messages in a selected sequence from the function keys and alphanumeric data entry means to said storage means with said calculator in said program storage mode;
- d. control means for controlling the operation of said calculator in response to the user program instructions stored in said storage means;
- e. an arithmetic means for performing arithmetic operations on data stored in said storage means in response to the user program instructions under control of said control means;
- f. output display means for displaying data stored in said storage means and for displaying said prompting messages; and
- g. means selectively coupling said response keys to said control means for controlling said calculator to selectively proceed in the execution of the user program in one of a plurality of different preselected manners whenever said response keys are actuated in response to the display of said prompting messages.
