Abstract
A method and apparatus for constructing edit mask entry fields for display panel data, in a system including a host processor, a workstation controller, and a number of workstations, each workstation having a keyboard and display screen. The edit mask entry field mask positions are protected when display panel information is modified, by special hardware and software operations performed within the workstation controller. In particular, certain keyboard edit function keystrokes are processed by the workstation controller to permit the edit functions to be performed, without disturbing the position or display panel presentation of preselected edit mask characters.
