Question

- use Assembly Language for IntelBased Computers.

- Irvine32 library is required

- Must use Microsoft Visual C++ to compile and run correctly

- Must make sure program runs correctly before submitting.

- It’s a 101 level course.

- DO NOT COPY from- another Chegg Expert Answers. They are wrong answers after compiling.

Test Score Evaluation
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 60 to 69 Grade D
Score 0 to 59 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 book’s 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.)

   grade BYTE ?,0
   grA BYTE "A",0
   grB BYTE "B",0
   grC BYTE "C",0
   grD BYTE "D",0

   mov grade,al
   mov edx, OFFSET grade
   call WriteString

   loop L1
    exit

   .IF (eax <= 100 && eax >= 0)
       .IF (eax <= 100) && (eax > 89)

           mov al,grD
       .ELSE
           mov al,grF
       .ENDIF

   .ELSE
       mov edx,OFFSET out_of_range
