Each task-related control block represents one unit of work. Control blocks serve as vehicles for communication throughout z/OS. Such communication is possible because the structure of a control block is known to the programs that use it, and thus these programs can find needed information about the unit of work or resource.

Refer to your processor user manual to find out how interrupts are acknowledged. It may be that the hardware saves some context on the stack of the interrupted thread, e.g. flags, instruction pointer. run by the kernel. On a context switch , a task's context is saved in the Task Control Block (TCB). A task's context includes: • thread of execution, that is, the task's program counter • the CPU registers and floating-point registers if necessary • a stack of dynamic variables and return addresses of function calls In fact, although not immediately apparent in Figure 1, a task is also an RTOS object because it is always defined by a Task Control Block (TCB). Figure 1 ...Pointer – It is a stack pointer which is required to be saved when the process is switched from one state to another to retain the current position of the process.
