Abstract

PURPOSE:To make it possible to announce the results of the inspections of a key information storage part obtained by allowing a channel unit to execute a series of channel commands by a chain. CONSTITUTION:The input-output system is provided which consists of channel unit 1, input-output controller 2 and large scale memory unit 3 stored with file 4 composed of records 5-0, 5-1 and having key information storage part K in each record and has the value of the key information storage part at the head of each record given a prescribed significance. Channel unit 1 executes a series of channel commands 6, including search commands search contents of key information storage part K, by a command chain, and input-output device 2 executes processes, of reading the value of the key information part of a record belonging to a file indicated in large-scale memory unit 3 on the basis of a search command, comparing it with a value indicated by the search command, and counting the number of times of coincidence, over all records belonging to the file, so that the channel unit side will be informed of the results.
