Program: Write a program to perform addition of a series of 8-bit numbers. The series have 100 (numbers).

Solution :

In the first program, we have been implemented the addition of two numbers.  In this, we demonstrate the addition of 100 (D) numbers. Firstly, the resulting sum of the first 2 numbers will be stored. To perform this sum, the third number will be added. This process will be repeated until all the numbers of series are added. A conditional  jump instruction will be utilized to implement the counter checking logic. The comments describe the purpose of each instruction.

The use of statement ORG 200H in this program is not necessary. We have used this statement here only to explain the way to use it. It will not affect the result at all. When a program loaded into the memory whatever is the address assigned for CODE, the executable code begin at the offset address 0200H due to the above statement. Same to DW, the directive DB reserves space for the list of 8-bit numbers in the series. The process for entering the program, coding and execution has already been discussed. The result of addition operation will be stored in the memory locations allotted to the label RESULT.
