program counter
     
         pc, or "instruction address register" a
        register in the central processing unit that contains the
        addresss of the next instruction to be executed.  the pc is
        automatically incremented after each instruction is fetched to
        point to the following instruction.  it is not normally
        manipulated like an ordinary register but instead, special
        instructions are provided to alter the flow of control by
        writing a new value to the pc, e.g. jump, call, rts.
