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 Range - Letter Grade 90 to 100 A

80 to 89 B

70 to 79 C

60 to 69 D

0 to 59 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. Display each integer and its corresponding letter grade (the Irvine32 library is required for this solution program because it uses the RandomRange procedure).

WRITE THE CODE IN ASSEMBLY LANGUAGE AND ALSO WRITE THE COMMENTS AFTER EACH CODE SO THAT I CAN UNDERSTAND PROPERLY
