Abstract

PURPOSE:To prepare a program efficiently in an easy-to-handle state by using a program diagram when a representation mode of arithmetic order and whether arithmetic is performed or not is preferably used or a control block diagram when a representation mode principally showing data arithmetic is preferable, and using them mixedly. CONSTITUTION:To display the control block diagram at a display part 6, an operation input part 1 is operated to move a cursor on the display screen of the display part 6 to a desired position on the display screen where a character or symbol is inputted and the key corresponding to the character or symbol to be inputted is operated; and then the code data corresponding to the key are inputted to an operation input storage part 2 and the character or symbol is displayed. An operation input-arithmetic instruction conversion part 3 converts the contents of the storage part 2 into an arithmetic instruction and stores it in an arithmetic instruction storage part 4. Thus, a program diagram is displayed on the screen consisting principally of the control block diagram together, so the basic arithmetic order is the same as before. Consequently, excellent program preparation environment is obtained.
