ABSTRACT:
In a display control system, when a continuous command requiring a continuous display updating process on a display screen is received from an application software, a corresponding display processing sequence is produced and stored in a time table. The time table defines titles of subroutines to be executed in terms of time. A timer interrupt routine is executed at every given timing for looking into the time table and identifying the subroutine to be executed at that time point, and for calling and executing the identified subroutine. Accordingly, the identified subroutines are executed in turn in the timer interrupt routines so as to accomplish the continuous display updating process. Since the continuous display updating process is executed as timer interruption, a simple command requiring a simple display updating process or a further continuous command can be received and processed while the former continuous display updating process is executed.
