As you execute the above assembly, whenever you encounter a label (i.e., immediately before you execute the instruction right after the label), write down the label's name, and the current register and memory values. You may not encounter all labels. The instruction addresses for each label are given in a comment on the same line as each label, if you find you need them. egisters emory Label S Sa StoSt1 SpSra 7770 7774 start 1142 8 858 8888 9999 7770 34 42
