Abstract

PURPOSE:To omit address calculation at the time of executing the field processing of a key part and a data part and the rewriting of an address register by continuously recording a counting part, the key part and the data part without forming gaps among them. CONSTITUTION:The counting part C, the key part K and the data part D are continuously recorded without forming gaps among these parts and gaps G2 are recorded on the rear of these parts together with an inter-record gap G3. Since no key part K exists in record '0', the record '0' consists of only the count part C and the data part D. Offset values up to the heads of respective fields are secured in a directory recorded on the gap G1. Thereby, the leading address of each record can be calculated. Since the data length of the counting part C is fixed and the count part C holds the data lengths of the key part K and the data part D, the key part K can be simply separated from the data part D.
