PURPOSE:To dissolve contradiction between memories, by editing rewriting data on a stack and performing data rewriting processes with the data on the stack when a flag is turned on at an abnormal time. CONSTITUTION:When a command is thrown in by means of a command throwing device 1 and a command processing program 7 is started, command input information 4 is analyzed and whether a command error exists or not is checked, and then, updated new data are stored in a stack 5 after edition. After the edition is completed, a data rewriting flag 6 is set to a data processing one and the content of the stack 5 is rewritten to aimed data 8. At the moment when the rewriting is completed, the flag 6 is returned to the non-processing one, and thus, processing of a rewriting command is completed. When abnormality occurs in the operation of this system, an abnormality occurring time program 9 is started and the flag 6 is referred. When a process is executed, the new data edited on the stack 5 are transferred to the data to be processed 8 and, if the process is completed up to the edition, the flag 6 is returned to the non-processing one and the command process is completed. |
