PURPOSE:To restart the processing from data in the correct re-execution start position of a source file by displaying and holding automatically the re-execution start position of the source file at the time of interrupting a data processing operation. CONSTITUTION:When a processing interruption instruction is issued from a processing interruption instructing device 6, the interruption processing means C of a CPU 1 interrupts the operation of a data processor A, and executes an interruption notice to a re-execution position informing means D. Also, the means C displays interrupting information on a display device 7 by using processing state information in a storage area 5. When the means D receives the interruption notice of the means C, the re-execution flag of the means A is turned on, the re-execution position of a source file 3 determined by deciding the processing state information of the area 5 is informed to the means A and held. Accordingly, when a start instruction is received from a processing start instructing device 2, and the re-execution flag is turned on, the means A executes successively a read-out processing from re-execution start position data from the means D without using the processed data to the file 3. |
