Abstract: A computer system which tends to give priority to user commands rather than to screen updates includes an event command queue (38) to which both user commands (from 14) and system screen update commands (from event controller 230) are applied. The information to be displayed is stored in a data container (226), and is accessed by a display processor (2280 in response to screen update commands from the output (38r) of the event queue (38). In order to allow user commands to have preference over system screen update commands, the event controller monitors the number of commands in the event queue, and does not issue a screen update command so long as the number of commands in the queue is greater than a predetermined or threshold number. Thus, a stream of user commands will preempt the generation of system screen updates, thereby giving preference to the user commands.
