Abstract
PURPOSE:To perform the loading of a job program to a real memory and the shunt from a main memory in a high speed, by writing the data on an escape page storage device with no intervention of an input/output device. CONSTITUTION:A main storage device MS forming a system consists of a monitor program region and a user program region. An escape page storage device EPS is formed with a magnetic bubble memory for instance. At the same time, the instructions of ENTRY, PURGE, BACKUP and RESTORE are added, and the job program of the device MS is shifted to the device EPS. Then the job program of the device EPS is transferred to the device MS; a region is secured on the device EPS; and the secured region of the device ESP is purged. As a result, the shunt and restoration of the job program can be carried out in a high speed to simplify the control program. Here CPU, CH and DK indicate a central processor, a channel and a magnetic disk device respectively.
