<p>PURPOSE:To grasp, at first sight, current states of on-line utilities, corresponding to application programs, without the need to change over screens, even if the host side starts plural APs. CONSTITUTION:A host 10 which starts APs exchanges data by way of a communication line 20 with a data transmission process control part 30 and a data reception process control part 40. A main control part 50 secures and releases the areas for child screens (1), (2),... (n) by way of memory control of an OS60. The input/output operation by an operator 100 with regard to a SLAVE screen is controlled by an input/output control part 51 and executed by using respective service functions of the OS60. Further, the input/output control part 51 displays, by using the OS60 having a multi-window displaying function, a slave screen on a CRT 90.</p> |
