PURPOSE:To realize the effective use of a virtual address space and reduction of the program executing time by recognizing presence of a proper variable part and a common invariable part that can be shared by other programs and storing these variable and invariable parts into a proper address space. CONSTITUTION:The virtual memories 21-23 contain proper address spaces 25-27. Then it is recognized that the proper variable parts (a) and (c) and an invariable part (x) that can be shared by other programs are contained in the programs stored in the memories 21-23. These parts (a), (c) and (x) are stored in the spaces 25-27. Thus the parts (a)-(x) are set into the spaces 25 and 27 when programs are loaded to the memories 21-23. Then the space 26 is expended to omit dynamic security and initialization of both parts (a) and (c).
