PURPOSE:To realize a stable operation of a computer system, by starting a program abnormality interrupt-processing routine when program abnormality occurs, so that a file belonging to a control-processing program which is stopped due to abnormality is released, and preventing a state that the whole computer system is stopped due to abnormality of a partial control-processing program. CONSTITUTION:In case when program abnormality occurs in a control-processing program 2a by some reason when a control program 2b is standby, abnormality of this program is informed to a program abnormality interruption control program 5, and also is informed to a program abnormality interrupt-processing routine 6a. Subsequently, the program abnormality interrput-processing routine is started, whether inhibition of write to a file 3 is being declared or not is decided, and when the inhibition of write is being declared, the write inhibiting declaration is released. After processing of the program abnormality interrupt- processing routine 6a is ended, the control-processing program 2a ends abnormality, and the control-processing program 2b can write to the file 3, therefore, the processing is continued. |
