PURPOSE:To reduce the number of logic processings, to improve the activity ratio of a main memory device, and to reduce load on its own electronic computer, by performing check accessing whether it is remote accessing or local accessing at a first stage of interruption processing. CONSTITUTION:When the remote file accessing of a user program from the electronic computer A to B is performed, an interruption processing part 10 investigates the accessing whether it is the remote file accessing, and performs the branching of remote/local accessing. Branched remote file accessing assembles the bit of parameter information of a supervisor call (SVC) in a packet at a packet generating part 11, and sends the packet from a transmission part 3 to the electronic computer B through a local area network (LAN) control part 4, and a LAN5. At the computer b, a packet receiving signal 6B receives the packet, and a local SVC issuing part 7 issues a local SVC call. And it is branched and processed according to the kinds of calls at a processing part 8, and a bit of information obtained from the above result is assembled in the packet by a response generating part 9, and is sent back again to the computer A by a transmission part 3B.
