Abstract: A method and apparatus for continuously updating a display of the coordinates of a light pen as it moves across a display screen involves executing a single iteration of an approximation calculation every refresh cycle of the display. The absolute screen coordinates are updated by the light pen tracking system and converted to application parameters written by the host computer into the display buffer work space. The orthogonal displacements, dx and dy, from a fixed reference point are determined. The distance and direction values from the reference point are converted to character form and inserted in the display buffer.

Abstract: In a distributed data processing system running multiple applications A1, A2, A3 located on a client system 4, resources specific to an application and which have no impact on the overall display at a server 2 are stored in application address space. Resources which have an effect on the overall system and which are managed in the client system are stored in protected, common, presentation address space in the client system. Resources which have an overall effect and are managed in the server system are stored in the display server system.

Abstract: PCT No. PCT/GB89/00883 Sec. 371 Date Apr. 2, 1991 Sec. 102(e) Date Apr. 2, 1991 PCT Filed Aug. 3, 1989 PCT Pub. No. WO91/02305 PCT Pub. Date Feb. 21, 1991.A workstation and data processing network in which having an application selection mode simultaneously displaying representations of both local and remote applications from which either remote or local applications may be started using a common selection procedure. When a remote application is selected a surrogate application is run on the workstation which establishes a communication with the remote processor. The provision of this common selection procedure means that the workstation is easier to use.
