Appendix B  Explanation : Consider that a byte is present in the AL register and second byte is present in the BL register. We have to multiply the byte in AL with the byte in BL. We will multiply the numbers using successive addition method. In successive addition method, one number is accepted and other number is taken as a counter. The first number is added with itself, till the counter decrements to zero. Result is stored in DX register. Display the result, using display routine. For example : AL = 12 H, BL = 10 H Result = 12H + 12H + 12H + 12H + 12H + 12H + 12H + 12H + 12H + 12H Result = 0120 H  Algorithm : Step I : Initialise the data segment. Step II : Get the first number. Step III : Get the second number as counter. Step IV : Initialize result = 0. Step V : Result = Result + First number. Step VI : Decrement counter Step VII : If count 0, go to step V. Step VIII :
