code segment
  mov ah,02h  
  mov cx,26  
  mov dl,65
lop:
  int 21h
  add dl,1  
  loop lop
  mov ax,4c00h
  int 21h
code ends
end

There is no code in stack and data segment of this program, mov dl,65 dl having the 65 in decimal which is code ascii code for the 'A'. and it will be increment by 1 by add dl,1 in to loop lop: int 21h is used to print the value to the output screen.

The variable cx having the value 26 which is decremented by 1 at every execution of iteration of the loop lop.

It will helps to print only 26 alphabets on to the screen.
