Functional structure of IBM virtual storage operating systems, Part III: Architecture and design of DOS/VS

DOS/VS represents a significant set of enhancements to the Disk Operating System. The addition of virtual storage support, additional partitions, and the relocating loader, among other items, extends the ability of the user to perform multiprogramming operations on System/370. Demands on the system operator are reduced, as are those on the scheduling function at the user installation. This type of operation, however, may require some changes in thinking by many DOS users, especially in considering factors that affect the total productivity of an entire computer installation.
