    Addition (subtraction is just adding a negative value) sets or clears the flags. Displaying flags and registers is just a display routing.
    The most difficult part of developing a program is understanding the problem.
    The second most difficult part is deciding how you're going to solve the problem.
    Actually writing the program (translating your solution into some computer language) is the easiest part.
    Please indent your code and use [HIGHLIGHT="VB"] [/HIGHLIGHT] tags around it to make it easier to read.
