void hello()
{
printf("hello every one");
}

#define BYTE unsigned char
#define WORD unsigned int
#define DWORD unsigned long

DWORD ptr_hello;

void main()
{
WORD* ptr = (WORD *)ptr_hello;
ptr[1] = FP_SEG(&hello);
ptr[0] = FP_OFF(&hello);

__asm
{
call ptr_hello
}
while(!kbhit());
}

我想做一下实验，结果是编译通过，不能执行，说CPU遇到无效的命令，请教为什么这样不行呢

WORD* ptr = (WORD *)ptr_hello;
应该是 WORD* ptr = (WORD *)(&ptr_hello);
