Abstract
Data comparisons are carried out between reference logical entities and logical entities proceeding from a file. The reference logical entities of different types are stored vertically in different horizontal zones (A, B, C) of a table in the order in which the entities of the same type are found in the file. In a control memory are recorded, line by line, items of control information relative to the comparison to be made with the reference entities of the zone of said table which corresponds to the line, items of storage control information and items of information for control of operations to be carried out at the end of comparison and/or storage, in particular the linkage of the processes to be carried out. The memory is read line by line while the logical entities from the file are received for comparison.
