This two-parcel i n s t r u c t i o n uses the lower-order 18 b i t s a s operand K. The
i n s t r u c t i o n causes t h e c u r r e n t program sequence t o t e r m i n a t e with a jump t o
address B i plus K i n CM.
This i n s t r u c t i o n allows computed branch point d e s t i n a t i o n s .
This i s the only
