A method and apparatus for incorporating windowing techniques into computer systems having a host processor executing applications programs, and interconnected through a plurality of controllers to a number of non-programmable and programmable terminals, by distributing the processing steps required for windowing between the host processor and the controllers; the host processor generates a data stream defining the window parameters, the data stream is receivable by controllers for either programmable or non-programmable terminals, each controller being adapted to construct and display the window on the display screen(s) which it controls.

Method and apparatus for assisting in the presentation and removal of

A method and apparatus for distributing the processing of cursor-independent scrolling functions, between a host processor and a workstation via a workstation control interface, the workstation control interface being connected to a plurality of workstations, wherein the host processor formulates a data stream incorporating scrollable panel data, definitions of cursor-independent scrolling keys, definitions of scrolling increments, and definitions of scroll indicators; the data stream is transmitted to the workstation control interface, which may be embodied in a workstation controller (or PWS), and the workstation controller (or PWS) formulates a display screen image for transmission to a workstation to which it is connected. A cursor-independent scrolling request received from a workstation is received by the workstation controller (or PWS) and processed for scrolling without further communication with the host processor.

Method and apparatus for local function key control of scrolling on

A method and apparatus for distributing the processing of certain remote terminal keystroke signals, and formatting of display panels according to user interface rules, to a workstation control interface in a system having a host processor connected to a large number of remote keyboard/display terminals through an intermediate workstation control interface.
