in assembly language ( using kip irvines 7th edition) .heres the question:

Create a procedure named CalcGrade that receives an integer value between 0 and 100, and returns a single capital letter in the AL register. Preserve all other register values between calls to the procedure. The letter returned by the procedure should be according to the following ranges:

Score 90 to 100 Grade A Score 80 to 89 Grade B Score 70 to 79 Grade C Score 0 to 69 Grade F

Write a test program that generates 10 random integers between 50 and 100, inclusive. Each time an integer is generated, pass it to the CalcGrade procedure. You can test your program using a debugger, or if you prefer to use the books library, you can display each integer and its corresponding letter grade. (The Irvine32 library is required for this solution program because it uses the RandomRange procedure.)

thanks
