• Objective

1. Manipulation of Arrays and Strings
2. More practice on basic assembly language commands and program structure.

• Pre-Lab Work:

     Read the material of Exp#4 from the lab manual.

• Lab Work:

        1. Write a program that reads 2 4-digit numbers as strings, then it calculates the sum and display it on the screen. Make sure to take the carry into account.

     You will need Indexed or Based Addressing Modes.
