Example: The highlighted three bytes in this example show the unique task control block (TCB) identifier. The first byte is the address space identifier. If this byte is zeroed, the TCB resides in the DFSMShsm primary address space; otherwise, it resides in a secondary address space. The next two bytes are the second and third bytes (middle two bytes) of the TCB address.
