THE DISPLAY SCREEN
The display screen is the primary means through which the terminal com-
municates with you.
Data entries into the terminal, regardless of source, will
normally be displayed on the screen.
Thus, you can proof information entered from
the keyboard, read information supplied from an external device, fill in forms,
and in general readily converse with other equipment in a data communications
system.
