显示闪烁的字符串

assume cs:code, ds:data

data segment

dw 1920,2080,2240,64
db 'welcome to JULNK'

db 82h,0ach,0f9h

data ends

code segment
start:
    mov ax,data
    mov ds,ax

    mov ax,0B800h
    mov es,ax

    mov cx,3
    xor di,di
    xor si,si
s1:
    mov ax,di
    mov bl,2
    div bl
    mov si,ax
    mov ah,[si+24]

    mov si,ds:[6]
    mov bp,[di]

    mov dx,cx
    mov bx,0

    mov cx,16
s2:
    mov al,[bx+8]
    mov es:[bp+si],al
    mov es:[bp+si+1],ah
    inc bx
    add si,2
    loop s2

    mov cx,dx
    add di,2
    loop s1
    mov ax,4c00h
    int 21h
code ends
end start

效果如下
