Abstract

PURPOSE: To obtain a file data processor that provides high-speed retrieval processing by setting various comparison conditions for one piece of information and then by making simultaneous comparisons.
CONSTITUTION: Record data in mass file 3 are input to comparator 7 successively. Pieces of condition data and comparison data from channel CH are set in comparison data memory unit 8. Control circuit 11 sets field length, obtained from channel CH through field assigning memory unit 9, in counter 13 and also controls comparator 7 with a cynchronizing signal from file 3. Comparator 7 compares the record data to pieces of comparison data and the results are displayed on display latch 12. Control circuit 11 receives those results by way of Boolean operation circuit 10 and when the results meet the conditions, the record data in record buffer 6 are transferred to a main memory unit.
