Test Score Evaluation

Create a procedure named CalcGrade that receives an integer value between 0 and 50, 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 displayed and should be according to the following ranges:

Score 45 to 50 Grade A Score 40 to 44 Grade B Score 35 to 39 Grade C Score 0 to 34 Grade F

Write a test program that

1. asks the user to enter integer between 0 and 50, inclusive. If the user enters invalid number, please display error message.

2. Pass it to the CalcGrade procedure.

3. Repeat steps 1 and 2 three times so that you collect three scores from the user and display the respective grade for each score
