Abstract
Abstract A novel graphic system and associated computer keyboard for easily and effectively programming a computer is disclosed. Specifically, a linear and structured flow chart using easy to understand graphic symbols allows transfer of the program represented by the flow chart directly into a computer via a keyboard which has associated graphic symbols designated on each of the individual keys.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
284 words
A method for entering a source program written in a high level graphic programming language into a data processing system for use with an interface such as a compiler or interpreter to generate a machine level object program, said data processing system having a standard typewriter style keyboard and a multicolumn graphic keyboard, said method comprising the steps of, preparing a single path programming flow chart consisting of accessory symbols, CPU symbols and re-route symbols, said preparing step including the steps of choosing selected ones of said accessory symbols, CPU symbols and re-route symbols to define a data processing program and arranging said chosen symbols in a single sequence from a commencement point in said single path flow chart to a termination point in said single path flow chart, selecting from said multicolumn graphic keyboard, comprising a first column of accessory symbol keys, a second column of CPU symbol keys and a third column of re-route symbol keys, a first symbol key corresponding to a first symbol in said single path programming flow chart and activating said selected first symbol key, and selecting and activating, in sequence, subsequent to activation of said first symbol key, keys from said multicolumn keyboard corresponding to each symbol in said single path programming flow chart from said commencement point in said flow chart to said termination point in said flow chart, whereby a user of said data processing system may input a computer program represented by said single path programming flow chart directly into said data processing system by selectively activating accessory symbol keys, CPU symbol keys and re-route symbol keys corresponding to said accessary symbols, CPU symbols and re-route symbols chosen for said single-path programming flow chart.

A method for entering a source program written in a high level graphic programming language into a data processing system for use with an interface such as a compiler or interpreter to generate a machine level object program, said data processing system having a standard typewriter style keyboard and a multicolumn graphic keyboard, said method comprising the steps of, preparing a single path programming flow chart consisting of accessory symbols, CPU symbols and re-route symbols, said preparing step including the steps of choosing selected ones of said accessory symbols, CPU symbols and re-route symbols to define a data processing program and arranging said chosen symbols in a single sequence from a commencement point in said single path flow chart to a termination point in said single path flow chart, selecting from said multicolumn graphic keyboard, comprising a first column of accessory symbol keys, a second column of CPU symbol keys and a third column of re-route symbol keys, a first symbol key corresponding to a first symbol in said single path programming flow chart and activating said selected first symbol key, and selecting and activating, in sequence, subsequent to activation of said first symbol key, keys from said multicolumn keyboard corresponding to each symbol in said single path programming flow chart from said commencement point in said flow chart to said termination point in said flow chart, whereby a user of said data processing system may input a computer program represented by said single path programming flow chart directly into said data processing system by selectively activating accessory symbol keys, CPU symbol keys and re-route symbol keys corresponding to said accessary symbols, CPU symbols and re-route symbols chosen for said single-path programming flow chart.
Claim 3
Dependent Claim
28 words
The improved method of claim 1 wherein there is further included the step of establishing a fixed relationship between keys on said graphic keyboard and said programming symbols.
Claim 4
Dependent Claim
44 words
The improved method of claim 1 wherein said entering programming information step includes the step of selecting keys on said graphic keyboard from functional groups of keys, said functional groups of keys representing selected computer functions of internal processing, editing, branching, and accessory selection.
