Abstract
PURPOSE: To perform the retrieval failure stably and easily in the electronic computer system, by providing the control information memory section receiving and memorizing the instruction designating to use the special applications to the specific peripheral memory unit from CPU.
CONSTITUTION: When a failure is taken place in CPU 5 and the system reset is issued to the controller 7, which confirms whether the bit corresponding to the magnetic tape memory unit 14 during being connected is set to the control information memory section 12 or not, and if it is set, the unit 7 immediately writes in the data of the specific pattern (representing the occurrence of failure and predetermined) to the unit 14 during connection via the control section, and if it is finished, the corresponding bit of the memory section 12 is reset, and next, whether other bits are set to the memory section 12 or not is checked, and the same step is repeated until the bits set to the memory section 12 are absent. On the other hand, when the on-line failure retrieval program performs retrieval operation, after rewinding magnetic tape, the read-in is continued until the data of the specific pattern is appeared, and the end of the data can be known stably and easily.
