 INCLUDE "EMU8086.INC" ; WE INCLUDE THE FUNTION TO USE NEW LINE
.MODEL SMALL   ; IN THIS COURSE ALL MODEL ARE SMALL
.STACK 100H    ; WE ALWAYS USE STACK 100H
.DATA     ; DATA SEGMENT, IF THERE IS NO DATA WE CAN TAKE BLANK OR REMOVE IT
.CODE

MAIN PROC       ; MAIN CODE START HERE

    ;AS DATA SEGMENT IS BLANK WE DO NOT NEED PROGRAMME SEGMENT PREFIX


    MOV AH,2   ; WE USE THIS TO PRINT SINGLE CHARACTER
    MOV DL,'?' ; TO PRINT WE MUST MOVE THE CHARACTER TO DL
    INT 21H    ; IT WILL INTRUPT THE WORK. THAT MENAS PAUSE THE CODE AND DO WORK WHAT SAY  ( INT 21H = interrupt handler 0x21 )



    MOV AH,1   ; WE USE THIS TO TAKE INPUT
    INT 21H    ; INTURPT THE COMMAND
    MOV BL,AL  ; IF WE TAKE ANY INPUT IT GOES TO AL, SO WE MOVE AL TO BL. NOW THE INPUT DIGIT IS IN BL, ONE MORE THING L = 8 BIT AND X = 16 BIT. SO WE CAN NOT
    ; MOVE AL = BX, WE CAN USE AX TO BX, BUT NOT AL TO BX
    ; IN MOV THE VALUE OF SECOND VARIABLE WILL TRANASFERED INTO FIRST VARIABLE


    PRINTN ""  ; WE USE THIS TO TAKE A NEW LINE


    MOV AH,2   ; WE SE THIS TO PRINT OUR OUTPUT, THIS FUNNTION ARE USED TO PRINT

    INT 21H    ; INTRUPT THIS COMMAND


    MOV AX,4CH ; TERMINATED THE CODE AND EXIT
    INT 21H
