    摘要: A data processing system in which one of several operating systems (OS) stored in the auxiliary storage is selectively loaded to the main storage so that an application program is run under the selected operating system. Each operating system is provided with a function of loading a new operating system to the main storage in response to the OS switching instruction issued as an operator command or a job control statement. The improved OS switching method eliminates time used to verify memory repeatedly and to load data sets used commonly by each operating system.
