Correspondingly, the of economic planning, statistical, data retrieval and keys of the words in the working file, which are used other problems requiring the processir/g of a large for the grouping, will be called the working keys, and volume of data places more exacting requirements the keys in the normative file the normative keys. In on the peripheral storage devices and on the efficiency general, grouping means the distribution of words in of their utilization. One of the most widely used forms the working file into groups for which the keys are of peripheral storage in Soviet data processing sys- identical to the normative key specified for this group. tems is magnetic tape. Although with modern tape If the size of the file to be grouped exceeds the stores it is possible to search for and make available capacity of the internal memory (and we shall be in- a required block of data without interrupting the com- terested in this particular situation related
