Abstract

PURPOSE:To collectively display a program of the output instructions, by constituting a series of element instructions organizing output instructions in group instructions in collected forms, and by displaying patterns by the group instructions. CONSTITUTION:Addresses designated by means of an address retrieval circuit 2 are given as the preset input of a counter 3, and become incremental by step pulses from a clock source 11 sent from an and gate 10. A reading circuit 4 extracts information from a memory 1 or 20 by the indication of the counter 3, and affords the information to a structure detecting circuit 5. The circuit 5 compares information from the memory and instructions memorized to a temporary memory 8, and writes the value to a temporary information memory 9 when it detects the change of structure. The change of the structure is collectively displayed to a pattern display device 23 through a detector 15, a group number decision circuit 16, a group information memory 20 and a display converting circuit 22.
