PURPOSE:To increase the number of advance processings by sorting a control table of a data control means of a processor into a checked area, an unchecked area and an unused area successively under use of a data phenomenon control block and controlling the processings of sequential input and output. CONSTITUTION:A control table is divided into six columns A-F. The column A stores a data phenomenon control block DECB which is under use. The columns B-F store a sequentially checked block DECB, the final DECB of a checked DECB, an unchecked DECB, the last DECB of the unchecked DECB, and an unused DECB respectively. Then the input/output processings are successively controlled. In such a way, the number of advance processings is increased. |
