下面是使用8086汇编语言实现每隔五行显示一条不同颜色色带的示例代码:
```
; 8086 assembly code to display color bars every 5 lines
; using the VGA graphics mode
.model small
.stack 100h
.data
.code
main proc
mov ax, @data
mov ds, ax
mov ah, 00h ; set video mode to 13h (320x200, 256 colors)
mov al, 13h
int 10h
mov cx, 0 ; set initial row position to 0
mov bl, 1 ; set initial color to black
mov bh, 0
draw_bars:
; draw color bars every 5 rows
cmp cx, 5
jne skip_bars
mov cx, 0 ; reset row position
; set color for next bar
inc bl
cmp bl, 16 ; there are 16 colors in VGA mode 13h
je reset_color
mov bh, 0 ; set intensity to normal
mov ah, 0Ch
mov al, bl ; set color
mov cx, 0 ; set column position to 0
mov dx, cx ; set row position to current row
int 10h
reset_color:
mov bl, 1 ; reset color to black
mov bh, 0
skip_bars:
; draw current row in current color
mov ah, 0Ch
mov al, bl ; set color
mov cx, 0 ; set column position to 0
mov dx, cx ; set row position to current row
int 10h
; move to next row
inc cx
; check if end of screen has been reached
cmp cx, 199
jne draw_bars
mov ah, 00h ; set video mode back to text mode
mov al, 03h
int 10h
mov ah, 4Ch
int 21h
main endp
end main
```
这段代码使用了 VGA 图形模式,并且通过每隔五行绘制一个不同颜色的色带的方式实现了显示多种颜色的效果。其中,使用 `int 10h` 中断调用来设置颜色和绘制像素点,同时使用 `cmp` 指令和条件跳转指令来控制绘制位置和颜色的改变。最后,使用 `int 21h` 中断调用来结束程序。
