Chapter 6 Applied Instructions Symbol S 1 ： Negative deviation S 2 ： Positive deviation S 3 ： Input value D ： Output value 6_ Explanation 1. This instruction adds the negative deviation in S 1 or the positive deviation in S 2 to the input value in S 3 , and stores the sum in D . If the input value in S 3 is less than 0, the instruction adds the negative deviation in S 1 to the input value in S 3 , and stores the sum in D . If the input value in S 3 is larger than 0, the instruction adds the positive deviation in S 2 to the input value in S 3 , and stores the sum in D . If the input value in S 3 is equal to zero, the instruction stores zero in D .
