上课时老师讲的一些经典的例子；错过了就太可惜了呀

cseg SEGMENT
     ASSUME CS:cseg,DS:cseg
star:
     mov ah,1
     int 21h
     call newline
     mov bl,al
     mov cx,8
next:
     shl bl,1
     mov dl,30h
     adc dl,0
     mov ah,2
     int 21h
     loop next
;
     mov dl,'B'
     mov ah,2

     mov ax,4c00h
     int 21h
