This document contains assembly language code that prompts the user to enter two numbers, subtracts the second number from the first, converts the result to an ASCII character, and displays the subtraction result. It initializes data segments to store prompts for inputting the numbers and displaying the result. The code uses DOS interrupts to display the prompts, get input, perform subtraction, convert the result to ASCII, and display the final output.
