PURPOSE:To prevent a stop of an operation whose stop is not desired, by stopping the operation in accordance with the prescribed priority, when a stop key has been depressed. CONSTITUTION:The priority can be set arbitrarily by an operator, and a control part 1 allows the operator to confirm successively an operation to be stopped in accordance with the prescribed priority, and thereafter, stops successively the operation to be stopped. Also, when a stop key 43 has been depressed, the stopped operation is informed to the operator. Moreover, the control part 1 displays a line which is being operated, and also, designates a line whose operation is to be stopped, from among lines which are being operated, of a display means. In such a way, when the stop key has been depressed, it is prevented that the operation whose stop is not desired is also stopped.
