64Dos环境编小游戏，内存不足了，求助~~~

[EmilMatthew]

最近学了些C下的图形函数，于是跃跃欲试想做一个DOS下的移豆的小游戏，就是一堆豆，
两个人拿，规定好每次拿的最大个数，谁拿走最后一粒算谁输，
游戏挺好写的，我想好了一个必胜的AI，而且，这个游戏是我第一个用C++写的程序。
不过，我把重点放在这个DOS下的程序的界面实现上，可以有人机对抗，人人对抗，还能设定游戏参数。
发现所有的东东都要自己来搞，好痛苦，也感觉实践了不少东西。
然而，当我这个程序搞了500多行，即主页面基本的框架已搭好，准备写游戏的交互部分时，出现问题了。
在进入INTRODUCTION或游戏的某个完法后，按ESC是可以回到开始的主画面的。再三次这样的进入和跳出后，BUG出现，即文字的字体模式全无，再试一两次后，强行从游戏中跳出。后来加了段捉ERROR的函数，发现问题了:
not enough memory to load font.
所以呢，我就开始想，到底是画面占用内存过多还是没有用类没有及时处理所造成。
如果是图形的问题，我还想先尝试尝试，因为知道方向了，GETIMAGE和SETIMAGE虽然还不太会用，但我相信还是能搞好的，等这方面有问题了再问。（用CLEARDEVICE发现无效，问题依旧。）
而我再注释掉大段图形操作的代码后，发现情况依旧，所以，怀疑是没有很好的处理无效类造成的。
所以我很想知道，问题到底是不是出在类上，如果是，还请高人指点我改如何做。
以下就是我写到了50%的代码，整体框架完全OK，但如果这个问题不解决，下面写下去的游戏是没法子玩的（只要把这个内存问题解决就好）。
千万别告诉我不要用DOS写游戏，这并不是我问这个问题的初衷。
主框架：（由于我是初学C++，我这里的几个类只不过是帮我更好的管理函数而已，分工明确。并不复杂。）
//编译环境TC++3。0。
//游戏中的消息
enum GameStatus{Win,Failure,Select,Gaming,Exit,GSFree};//游戏游程
enum GameModes{PvsC,PvsP,CvsC,OP,Intro,GMFree};//游戏模式，PERSON VS COMPUTER。。。，玩法简介及属性设定也在其中。
GameModes GModes=GMFree;
GameStatus GStatur=Select;

void main(void){
ScreenLayOut SC;//负责画静态图形的类
GameKeyControl KC;//游戏中的键盘响应类
GameMode GM;//主游戏中的游戏模式类

while(GStatur!=Exit){
SC.ErrorDetect();//错误捕捉类
switch(GStatur){
case Select:

SC.GraphicStart();
SC.Selectgame();
KC.Selectgame();//ZhongDuan Choose
if(GModes==Intro){ SC.Introduction();
KC.Introduction();//ZhongDuan Return
GModes=GMFree;
break;
}
if(GModes==OP){ SC.Option();
KC.Option();//ZhongDuan Return
GModes=GMFree;
break;
}



else if(GStatur!=Exit)GStatur=Gaming;
break;
case Gaming: GM.GameCommand();
break;
}
}

getch();
SC.GraphicEnd();
}

看不咋懂！可能是你程序中的处理太占空间，或是申请了全局的数组空间太大！
