PURPOSE:To make the display easy to confirm visually and to facilitate checking a program by displaying data words, which are commanded in a preceding block but are not commanded in a current block, distinctively from and together with commanded data words. CONSTITUTION:A part program is read from a part program memory 1 to a one-block reading part 2 block by block, and commanded data words are stored in individual addresses of an address-classified data word storage part 4 by a data word storage control part 3. A non-commanded address determining part 5 determines non-commanded addresses on a basis of one block read by the reading part 2. A one-block non-commanded data word discriminating part 7 discriminates commanded data words, non-commanded necessary data words, and non-commanded unnecessary data words from one another and sends them to a display part 8. Thus, they are displayed on a CRT 81 together distinctively from one another.
