下面是小弟的一段代码，在一个文本框中输出一些信息，但是小弟不会做，因为有时信息太长的话会碰到边界，不能换行，小弟不会处理！于是用了个笨办法，还是有问题！请大侠们赐教！帮忙写一个新的算法救救小弟！谢谢！

outtextxy(51,42,"how the memory is delivered when a C language program is to run! And it is");
outtextxy(51,43,"programed by Zhang JIhui for a graduated design! If you want to escape this");
outtextxy(51,44,"frame,please press ESC on the keyboard! ");
