8086 program to Print a 16 bit Decimal number
• Last Updated : 01 May, 2019

Problem: Write a 8086 program to Print a 16 bit Decimal number.

Examples:

```Input: d1 = 655
Output: 655

Input: d1 = 234
Output:234 ```

Explanation:

1. load the value stored into register
2. divide the value by 10
3. push the remainder into the stack
4. increase the count
5. repeat the steps until the value of the register is greater than 0
6. until the count is greater than zero
7. pop the stack
8. add 48 to the top element to convert it into ASCII
9. print the character using interrupt
10. decrements the count

Program:

Note: The program cannot be run on an online editor , please use MASM to run the program and use dos box to run MASM , you might use any 8086 emulator to run the program
