Assembly language program to Subtract two numbers by Static inputs

Code 

org 100h

.stack
.data
.code
main proc
        mov ax,6      ;this is the first value
        mov bx,3      ;this is the second value
        sub ax,bx      ;the result will save in first register (ax)
        
        mov dx,ax      ;move ax to dx register for display
        add dx,48          ;in assembly language ASSCI values are added so convert ASSCI value we add 48
         
        mov ah,02      ;give 02 to ah register (used for display)
        int 21h          ;now generate dos interrupt

        mov ah,4ch      ;give 4ch to ah (used terminatey)
        int 21h             ;now generate dos interrupt
    main endp
end main

Output
