PURPOSE:To decrease the number of software stages and to reduce greatly the deterioration of system processing performance as well as system faults, by handling the read-out contents of a storage circuit given from an access controller as the intra-file record addresses to be successively recorded. CONSTITUTION:An input/output circuit 11 of an access controller 5 receives an indication and a selection signal supplied from a file controller 3 or 4 and delivers the selection signal to a selection circuit 9. The circuit 9 selects an address from a storage device 8 based on said selection signal and increases its holding contents by one. The circuit 11 transmits the read-out contents given from a replacement circuit 10 to the controller 3 or 4 which supplies an indication and a selection signal via a signal line 12 or 13 and records them successively. |
