Abstract
A process for partially swapping real storage areas used by a program is utilized in a computer system which executes programs by multiprogramming under control of a virtual storage type operating system. A first portion of a real storage area, allocated to a program to be swapped out, remains allocated to that program while the contents of a second portion of the real storage area are saved in an auxiliary storage so that the second portion is deallocated from that program. The saved contents of the second portion stored in the auxiliary storage are loaded in the real storage when the program is to be swapped in.
