PURPOSE:To enable the continuous execution of a job to be performed, by providing a backend processor on a controller. CONSTITUTION:A job continuous execution indication message 50 is constituted of a parameter which indicates a job name (job number) and an output system, etc., with an identification number, and execution control information is arranged with them in a sequence of execution order. The backend processor BP11, when receiving the above stated job continuous execution indication message 50, decodes the message by an interpreter 17, and obtains a catalog file by indicated job number or job name. And it generates a managing table by applying a job chain, and issues the indication of execution to a loader 18 in order. The loader 18 loads a prescribed program on a memory provided in the backend processor (BP)11 from a program library 4, and applies start up. When the execution of a loaded program is completed, the interpreter 17 executes the job continuously based on a job catalog chained at the next stage.
