<p>PURPOSE:To decrease the number of program steps for a process where a screen to be displayed next is searched by using a screen hierarchical managing table to manage a linkage relation between a screen which is under display and a screen to be displayed next. CONSTITUTION:In a central supervisory processing system 21, an overall system constitution diagram, the picture information 29 on an intra-office system diagram of a terminal station 22A, etc., and a screen hierarchical managing table 10 are stored in a memory 28. The table 10 is loaded into a processing part 27 and used. When an operator supplies an indirect instruction input (m) for search of a screen via an input part 25, the part 27 decides the number of the screen to be displayed next based on the table 10. The desired picture information is loaded from the memory 28 and outputted to a display via an output part 26. Thus the operator can easily display the next screen in response to the present display screen.</p> |
