PURPOSE:To improve the execution efficiency of plural continuous strokes by setting the number of storage blocks of a main memory device at a value in which at least one is added on the maximum number required for the development of data with maximum length, and retrying the stroke by a data execution means when abnormality is generated at the time of executing the plural strokes. CONSTITUTION:The number of storage blocks of the main memory device 4 is set at the value in which at least one is added on the maximum number required for the development of the data with the maximum length out of a data group corresponding to the plural strokes. And the data execution means 2 is constituted in such a way that it retries the stroke when the abnormality is generated at the time of executing the plural strokes. In such a way, it is possible to improve the execution efficiency of the plural continuous strokes, and also, to retry the stroke immediately without performing complicated wok even when the stroke under execution is interrupted accidentally. |
