Abstract

PURPOSE:To ensure the simple head leading of a file, by dividing the process data of each input/output into plural blocks and providing the control byte into which the information discriminating each block at the head of each block. CONSTITUTION:A control circuit 31 delivers a data reading instruction given from a cassette memory 12 to a control circuit 32. As a result, only the control data is applied to a discriminating circuit 35 via a gate circuit 34. The circuit 35 counts up the contents of a file present position register 37 every time the control data is applied. while a comparator 38 compares the command file position with the file present position. If a coincidence is obtained, a coincidence signal CIN is read and delivered to the circuit 32. Thus the reading is stopped to complete the heat leading of a command file.
