LAB 3 (take 3 intials and print them in left mergin)

;   Write a program to (a) prompt the user, (b) read first, middle, and
;   last initials of a person's name, and (c) display them down the
;   left margin.
;   Sample execution:
;   ENTER THREE INITIALS: JFK
;   J
;   F
;   K


.MODEL SMALL   ; IN THIS COURSE ALL MODEL ARE SMALL
.STACK 100H    ; WE ALWAYS USE STACK 100H


.DATA     ; DATA SEGMENT
    STR DB 'ENTER THRRE INITIALS: $'        ; to print the line  we store it on STR
    STR1 DB '',0AH,0DH                      ; we give new line
    FIRST DB ?                              ; here we take a variable where we first number
    STR2 DB '',0AH,0DH                      ; here also we give a new line
    SECOND DB ?                             ; here we take a variable where we second number
    STR3 DB '',0AH,0DH                      ; here also we give a new line
    THIRD DB ?                              ; here we take a variable where we third number
    STR4 DB '$'                             ; here we use $ to end the string
