Write an assembly language program that reads a set of integers from the keyboard and displays their sum on the screen. Your program should read up to 20 integers (except zero) from the user. The input can be terminated by entering a zero or by entering 20 integers. The array of input integers is passed along with its size to the sum procedure, which returns the sum in the AX register. Your sum procedure need not check for overflow.

 

Write a procedure max that receives three integers from main and returns the maximum of the three in AX. The main procedure requests the three integers from the user and displays the maximum number returned by the max procedure.
