Appeal No. 1997-2862
Application 08/069,052
The present invention relates to a controller for the ARC/INFO geographic information system
(GIS) which enables command line (TTY) control using a keyboard and graphic user interface (GUI)
control using a mouse or keyboard without manually switching by the user.
Independent claim 11 is reproduced as follows:
11. A method for enabling command line (TTY) and graphic user interface (GUI) control of a
main program in a computer which schedules multiple threads of operations and in which a TTY
operation at the top of a first thread supersedes GUI operations at the top of a second thread, said
main program inserting a TTY control operation at the top of said first thread, comprising the steps of:
(a) inserting a dummy GUI operation on top of said TTY control operation in said first thread
that suspends said TTY control operation and causes said main program to be controlled by said GUI
operation on top of said second thread;
(b) displaying a dummy window as an artifact of said dummy GUI operation; and
(c) in response to a TTY control command, removing said dummy GUI operation from said
first thread and deleting said dummy window to cause said main program to be controlled by said TTY
control operation and thereby avoid the need for a user to manually dismiss the dummy window,
feeding said TTY control command to said main program, scheduling said first thread, and inserting said
dummy GUI operation on top of said TTY control operation in said first thread to cause said main
program to be subsequently controlled by said GUI control operation in said second thread.
The Examiner relies on the following reference:
Mauney et al. (Mauney) 5,214,757 May 25, 1993
(filed September 29, 1992)
Claims 11 and 13-20 stand rejected under 35 U.S.C. § 103 as being unpatentable over
Mauney in view of Appellant's admitted prior art.
