Hierarchically layered tables are stored in a mass memory. Each table has entries containing a symbol of a telecommunication network item, location data of the symbol to be displayed in a display unit, and an identifier specifying a lower-layer table. A pointing device is used for selecting an symbol being displayed corresponding to a symbol of an upper layer table. A relocation processor is responsive to a keyboard command for detecting a given entry of the upper layer table that contains the selected symbol, reading information from all entries of a lower layer table specified by the given entry of the upper-layer table, securing a space around the selected symbol using the location data of the read information, and storing it into that entry of the upper layer table. A display processor displays, in the second space, multiple symbols stored in the given entry of the upper layer table. |
