The following are all common addressing modes EXCEPT

  • A.register direct, naming a register as the operand
  • B.indexed, adding a register to a displacement
  • C.indirect, using a register as a pointer to the operand
  • D.recursive, in which the operand names another instruction

Answer: D

Correct answer: recursive, in which the operand names another instruction

There is no such addressing mode: an operand names data, not an instruction. The other three are standard - register direct, indexed and indirect - and the set available on a machine largely determines how much work the generator must do to reach an operand.
