MOUSE POINTER HAVING CHANGEABLE EMULATION MODE

摘要

PURPOSE: To permit a mouse to control a pointer in an emulation window so as to be like the pointer of a target system and also like the pointer of a host system over a whole display. CONSTITUTION: When a host means 2 enters a host mode in a box 70(B70), it waits interruption in B72. The interruption is inputted by the button of a mouse or a key of keyboard. At the time of interruption, it is tested whether or not the change-over of an emulating mode is indicated from the host mode. When interruption is the emulating mode, the host 20 gets away from the host mode in B78 and becomes the emulating mode in B80. The host 20 updates the display and a memory and executes another operation in the emulating mode while waiting interruption in B82 in same way.
