PURPOSE:To make the identification of altered part easy, by adding a function displaying the altered part with a mark in a block diagram together with forming and display function of the new block diagram corresponding to the change in a program. CONSTITUTION:In inserting an AND element between blocks 2 and 3, a cursor is matched to a block 3. An address 2606 number indicated with the final address pointer EP is stored as the final address before the correction. On the other hand, the head address 2603 of an operation specification table 1152 is inserted to the 3rd of an operation sequence table 1151, and the 3rd one is shifted to the 4th. Next, the content of the table 1151 is compared with the final address 2606 address before the correction sequentially to discriminate that only macro AND designated at the 2603 address of the table 1152 is inserted. Thus, the 4th operation macro block number is 3 as originally unchanged and the block number of the macro AND newly inserted is displayed as 2A newly. |
