To write a program in 8086 assembly language that converts a four-digit packed BCD number to ASCII digits and then prints them, we'll go through the steps one by one:

Step 1: Load the BCD number from memory Step 2: Convert packed BCD to unpacked BCD Step 3: Convert unpacked BCD to ASCII digits Step 4: Print the ASCII digits

Let's write the program and explain each step in detail:

.MODEL SMALL
.STACK 100H

.DATA
    BCD_NUM DW 1234H    ; Replace '1234H' with your desired BCD number

.CODE
    MOV AX, @DATA       ; Initialize data segment
    MOV DS, AX

    ; Step 1: Load the BCD number from memory
    MOV AX, BCD_NUM     ; Load the packed BCD number into AX register

    ; Step 2: Convert packed BCD to _____ _______ ___ _____ _________ ______ _________ _________.
