PURPOSE: To decide easily the RAM data for control and to simplify the production of a program by securing a RAM disposition equal to a display data array and also delivering the framing for screen display.
CONSTITUTION: Plural terminal 12 are connected to a CPU11 for communication of a controller 1 of a CRT monitor system, and the communication is carried out between the controller 1 and the terminals 12. The various data given from terminals 12 are stored to a RAM4. At the same time, a CRT display device 2 is connected to a serial/parallel converter 7 of the controller 1 together with a key switch connected to the device 2. The screen display of the device 2 has an array equal to the data array of the RAM4. Then the controller 1 displays only the data on the address indicated by the control of a CPU5 on the device 2 as it is. Furthermore the controller 1 delivers data to the device 2 every fixed period of time.
