Abstract

In communications from a host data processor, such as the IBM System/370, to a receiving word processing display workstation, such as an IBM Displaywriter, the material communicated from the host is customarily displayed on the display terminal. In the case where an ongoing data stream is being communicated to the Displaywriter, provision must be made for screen updating. In conventional data processing operations wherein a central processor such as a 370 communicates with a plurality of display terminals, such as IBM 3270 terminals, it is conventional procedure for the terminal screens to be updated periodically as the data is received from the host processor. In accordance with the present approach, all of the received data is buffered until data indicative of a complete screen has been received from the host processor.

Communicating Word Processors Workstation Screen Updating

In communications from a host data processor, such as the IBM System/370, to a receiving word processing display workstation, such as an IBM Displaywriter, the material communicated from the host is customarily displayed on the display terminal. In the case where an ongoing data stream is being communicated to the Displaywriter, provision must be made for screen updating. In conventional data processing operations wherein a central processor such as a 370 communicates with a plurality of display terminals, such as IBM 3270 terminals, it is conventional procedure for the terminal screens to be updated periodically as the data is received from the host processor. In accordance with the present approach, all of the received data is buffered until data indicative of a complete screen has been received from the host processor. At this point the whole screen is updated or changed. The present expedient provides advantageous results over systems wherein the screen is updated at the receiving terminal as the information is received. In addition to purported aesthetic and operator attention characteristics, the present approach represents a considerable saving in software processing time. In a communications protocol, such as SNA (System Network Architecture), where data is transmitted in chunks, there are a great deal of software routines which must be repetitively carried out with each screen update. This is part...
