Control system for data coupling execution

Abstract

Abstract PURPOSE:To execute a data coupling processing without preparing a sufficient output use memory area, by providing a means for informing a head position of an unprocessed data train or the number of processed cases, when the data coupling processing has been discontinued, and starting the processing from a designated position of the data train. CONSTITUTION:When it is detected that an output use memory area has become full and the processing is discontinued, an output data piece number value of a counter saving register group 12 is inputted to an output position and output piece number storage means 33, and the first data position of this complicated processing which is being executed is written in an unprocessed head position or processed case number storage means 32. A data coupling processing part 1 reads the contents of a position and case number storage means 31 and the unprocessed head position and processed case number storage means 32, and can restart a data coupling processing from a processing start position. When the processing has been discontinued, even in case when an especially complicated processing has been being executed, it can be restarted from a convenient pause. In this way, the data coupling processing can be executed without preparing a large output use memory area.
