Set System Pointer from Pointer (SETSPFP)

Operand 2: System pointer, space pointer, data pointer, instruction pointer or label pointer.

Built-in number for SETSPFP is 142.
SETSPFP (
         source_pointer   : system pointer OR
                            data pointer OR
                            space pointer(16) OR
                            label pointer
) :   system pointer /* receiver */

Description:   This instruction returns a system pointer to the system object addressed by the supplied pointer.

If operand 2 is a system pointer, then a system pointer addressing the same object is returned in operand 1 containing the same authority as the input pointer.

If operand 2 is a space pointer or a data pointer, then a system pointer addressing the system object associated with the space addressed by operand 2 is returned in operand 1. The system object associated with machine supplied spaces used for automatic, static, activation group-based heap space and handle-based heap space storage is the process control space (PCS) object with which they are affiliated. The system object associated with a teraspace is the PCS object used by the process which contains the currently executing thread.

If operand 2 is an instruction pointer or label pointer, then a system pointer addressing the program system object that contains the instruction or label addressed by operand 2 is returned in operand 1.

If operand 2 is an unresolved system pointer or data pointer, the pointer is resolved first.
