PURPOSE:To develop easily a job by registering and managing not only a link information of a resource but also its name, in a table for managing the resource on a memory. CONSTITUTION:When a computer is started, a global job control block (G.JCB)1 and a global access descriptor (G.ACD)2 are generated. A task 3 and various resources 4 are generated as necessary, and registered in the G.ACD2. A local job control block (L.JCB)9 registers and manages a task 11 and various resources 12 in a local access descriptor (L.ACD)10. An address on a memory on which a name of each resource and its resource are loaded is mentioned clearly on the ACDs 2, 10, and accordingly, an area on the memory on which a necessary resource is loaded can be detected easily.
