原型：extern void DispBCD(int);
用法：#include <system.h>
功能：顯示七段數(shù)碼管數(shù)字
說明：調用后在屏幕左側圖標區(qū)顯示對應數(shù)字。
顯示最大值為999。
舉例：
// DispBCD.c
#include <system.h>
main()
{
int i;
i=9;
clrscr();
printf("Now Display 9");
DispBCD(9);
getchar();
i=99;
clrscr();
printf("Now Display 99");
DispBCD(99);
getchar();
i=999;
clrscr();
printf("Now Display 99");
DispBCD(999);
getchar();
return 0;
}
相關函數(shù)：無
