Chapter 2.2, Problem 2QE

In the text, JUMP instructions were expressed by identifying the destination explicitly by stating the name (or step number) of the destination within the JUMP instruction (for example, “Jump to Step 6”). A drawback of this technique is that if an instruction name (number) is later changed, we must be sure to find all jumps to that instruction and change that name also. Describe another way of expressing a JUMP instruction so that the name of the destination is not explicitly stated.
