Abstract

This invention provides the capability of displaying cursor-dependent status fields on dependent display stations without severely degrading performance. In a word processing environment, there are a number of fields on a display screen that need to be updated based on the cursor position. However, updating these fields on each keystroke potentially causes an unacceptable performance burden on the I/O processor (Work Station Controller (WSC) if the operator is keying at a fast rate. If updating these fields is deferred until the cursor has come to rest for a small period of time (100 to 200 milliseconds), the performance burden is considerably reduced at the expense that the fields are not always current.
