这是我做的贪食蛇游戏，在游戏中属于比较简单的，只有近500行，主要设计思想是以数据段的数值

作为80*25屏幕上的坐标，然后用一些中断将其显示就行。所以编程时主要考虑对数据段中数据的改变

对于贪食蛇这款游戏，核心思想是控制“蛇头”（第一个数）的变化，而蛇身只要跟着蛇头移动就行-This is a pivotal game that I do in the game are relatively simple, only about 500 lines, the main design idea is based on the value of the data segment

　80* 25 on the screen coordinates, and then some disruption to its display. So the main consideration when programming change to the data in the data segment

　On the Snake game, the core idea is to control the "snakeheads" (first number) changes, while the snake followed by snakeheads move
