PROBLEM TO BE SOLVED: To provide an interactive file updating processing system for delay type processing system with which the load of a host processor can be reduced by decreasing the number of times of communication and the host processor can be easily recovered without requiring any update journal of terminal equipment even in the case of fault. SOLUTION: This system is provided with a front end processor(FEP) 12 having an input log file 123 and a blocking table 124 connected through a packet line 14 to terminal equipment 11 and connected through a high-speed LAN 15 to a host 13. In this case, the file 123 exists on a disk and preserves all the update execution request telegraphic messages from the terminal equipment 11, and the table 124 exists on a memory and preserves the fixed number of update execution request telegraphic messages 112 from the terminal equipment 11. When the update execution request telegraphic message 112 is received from the terminal equipment 11, the FEP 12 outputs the contents of the telegraphic message to the file 123 and the table 124 and returns a response telegraphic message to the terminal equipment 11 after blocking. |
