Problem:

The purpose of this lab is to introduce more complex data manipulation using assembly language. You will be exploring concepts relating to data storage and looping structures while analyzing a random set of grade values. Your program will calculate the minimum and maximum grades along with the average and median grades of the set.

Assignment

Make a project that will allow you to enter a random set of grades and provide storage for the results in RAM. Use meaningful names for your RAM storage locations to help make your code more readable. You should provide locations for your grade data, minimum grade, maximum grade, average grade, and median grade. Allowed grades are between 0-100. You will indicate the end of the grade set with a value of -1.
