The name PRIOR is understood to encompass those task management routines permitting
the control of tasks with the aid of categories and priorities
the monitoring and control of the system workload by means of internal mechanisms.
In effect this implies
management of the resources main memory (MM) and CPU, including execution of the corresponding control functions
(see section "Activating/deactivating tasks" and section "Initiation/deinitiation of tasks")controlling the tasks via wiat queues
(see section "Controlling tasks via queues")
The concept is based on priority control without changing the range of resources allocated. This means that the influence of systems support is restricted merely to determining which one of a number of users will first obtain a requested resource. The influence of systems support on what share of a resource's capacity will be available to any applicant within a given time period is negligible.
