on the compiled results, it can be found that; JMP short S1 is compiled with the following instructions: EB F6; From the above, the offset is: F6; The offset is expressed by the complement, by the note two in the book; We can figure out that the F6 corresponds to a signed decimal number of-10.; From here, we can know that this instruction is to add the IP value-10.; So, let's see what the address ip-10 points to? ; By the result of the compilatio
