ABSTRACT:
A device for controlling the handling of data which comprises a main memory for storing a large number of record data items in a state marked off by record-positioning codes, said respective record data items being formed of series-arranged word data items of variable word length, each containing a plurality (including one) of characters marked off by word-positioning codes, wherein a processing memory is a matrix type formed of columns containing words each having a certain number of characters falling within a specified range and a plurality of rows, and designed to store at least one record data item read out of the main memory; characters constituting the foremost word data item of a record data item read out of the main memory are written with shifting in a given row of the matrix memory, starting with the first character of said word data item; upon detection of a word positioning code immediately following said foremost word data item, the succeeding word data item is written in a row adjacent to said given row of the matrix memory; and readout of data items from the main memory to each row of the matrix memory is brought to an end when a record-positioning code following the last word data item of each row is detected.
