Data display arrangements.

摘要

In a data display arrangement which is adapted to operate as electronic information apparatus, a quantity of data stored in a display memory is displayed as an entity on a CRT display device. The stored data is selected from a large background memory under processor control in response to user command signals. The mode of selection involves the progressive comparison of each of a sequence of command signals with key data codes to transfer discrete portions of the data from the background memory to the display memory as determined by each command signal in conjunction with each preceding command signal. Fig. 5 shows a flow chart of the selection mode.
