Method for cursor control of scrolling movements on certain computer workstations

Claim 1

A method of expanding and enhancing cursor control and scrollable panel display in a plurality of dependent workstations connected to a workstation controller, comprising the steps of: a) prestoring, in said workstation controller, format tables to describe display screen scrollable panel areas, selection fields and entry fields, list entries and informational text, and scrollable panel data, all relating to cursor position, for each of said plurality of dependent workstations; b) asynchronously receiving cursor keystroke signals in said workstation controller from any of said plurality of dependent workstations; c) identifying, within said workstation controller, as to each of said asynchronously received cursor keystroke signals, the particular dependent workstation from which such signal is received, and retrieving the scrollable panel data for said particular dependent workstation; d) developing, within said workstation controller, a new cursor target position and display screen image corresponding to the received cursor keystroke signal from the particular dependent workstation and the retrieved scrollable panel data; and e) transmitting a new display screen image to the particular dependent workstation to modify the cursor target position and display screen image in said particular workstation to correspond to the workstation controller-developed new cursor target position and display screen image.

Claim 2

A method of expanding and enhancing cursor control and scrollable panel display in a plurality of dependent workstations connected to a workstation controller, comprising the steps of: a) prestoring, in said workstation controller, format tables to describe display screen scrollable panel areas, selection fields and entry fields, list entries and informational text, and scrollable panel data, all relating to cursor position, for each of said plurality of dependent workstations; b) asynchronously receiving cursor keystroke signals in said workstation controller from any of said plurality of dependent workstations; c) identifying, within said workstation controller, as to each of said asynchronously received cursor keystroke signals, the particular dependent workstation from which such signal is received, and retrieving the scrollable panel data for said particular dependent workstation; d) developing, within said workstation controller, a new cursor target position and display screen image corresponding to the received cursor keystroke signal from the particular dependent workstation and the retrieved scrollable panel data; and e) transmitting a new display screen image to the particular dependent workstation to modify the cursor target position and display screen image in said particular workstation to correspond to the workstation controller-developed new cursor target position and display screen image.

Claim 5

A method of controlling cursor-sensitive scrolling on a plurality of dependent workstation display screens respectively located in a plurality of dependent workstations, from a single workstation controller, comprising the steps of: a) prestoring, in said workstation controller, format tables and scrollable panel area definitions as to each of the plurality of dependent workstations; b) independently receiving cursor keystroke signals from each of said plurality of dependent workstations into said controller; c) comparing each received cursor keystroke signal in said workstation controller with the format table and scrollable panel area definitions for the dependent workstation corresponding to the independently-received cursor keystroke signal; and d) forming a new display screen image in said workstation controller and transmitting said new display screen image to the dependent workstation corresponding to the independently-received cursor keystroke signal, for each independently-received cursor movement keystroke signal, to initiate a scrolled display panel area on the dependent workstation corresponding to the independently-received cursor keystroke signal.

Claim 6

A method of controlling cursor-sensitive scrolling on a plurality of dependent workstation display screens respectively located in a plurality of dependent workstations, from a single workstation controller, comprising the steps of: a) prestoring, in said workstation controller, format tables and scrollable panel area definitions as to each of the plurality of dependent workstations; b) independently receiving cursor keystroke signals from each of said plurality of dependent workstations into said controller; c) comparing each received cursor keystroke signal in said workstation controller with the format table and scrollable panel area definitions for the dependent workstation corresponding to the independently-received cursor keystroke signal; and d) forming a new display screen image in said workstation controller and transmitting said new display screen image to the dependent workstation corresponding to the independently-received cursor keystroke signal, for each independently-received cursor movement keystroke signal, to initiate a scrolled display panel area on the dependent workstation corresponding to the independently-received cursor keystroke signal.
