PURPOSE:To print out only a necessary data, and to save waste, by holding a data of an executed program in a file, and driving an output queue control part only in case of satisfying the condition designated by a control table. CONSTITUTION:A program executing part 20 advances its processing, storing an execution result in an output file 23. When the execution ends, a completion code is sent to an output queue control part 22 through an end processing part 21. A control table 10 is controlled by an operation control part and a job control part, which are not shown in the figure, and holds an output condition expression. The output queue control part 22 reads out the output conditional expression from the control table 10, compares it with the transferred completion code, holds the information regarding the output file 23 in an output file information part 24 when said condition is satisfied, and after that, connect it to an output queue holding part 25. After that, a data held by the information holding part 24 is printed by a line printer which is not shown in the figure. In this way, unnecessary printing is omitted. |
