ABSTRACT:
A system and method for manipulating a plurality of data records. Each record is comprised of a plurality of bits and is identified by a unique record address value. A portion of each record comprises a keyfield and each keyfield is generally divided into a plurality of sub-keyfields, each having a different order of significance. The sub-keyfield value of greatest significance of each record is utilized to set one memory location in the column of a matrix memory means corresponding to the record address value of that record, said memory location being in the row of the matrix memory means corresponding to the sub-keyfield value of that record. The column position values of the set memory locations are then arranged in order of row position, and the column position values derived from the same row are grouped together. The process is successively repeated, separately for each group of column position values, for the sub-keyfield value of next greatest significance of each record having a record address value corresponding to a column position value in said group as long as at least one group of column position values remain.
