Simple Project in Assembly Language - Menu

This was supposed to be my project in assembly language. (The truth is, I have never tried to master assembly language programming and I have already forgotten how the code below works. LOL! But I'm going to share it anyway.)

I thought I did not have a copy of this but I found a copy on my previous blog.

They called this "Menu"

The code below is just part of the program. Download the whole program here or here. 
This should be assembled using the A86 Assembler by  Eric Isaacson.


Enjoy!
