单片机的一个小疑点

单片机的一个小问题？
#include<reg52.h>
#define DataPort P0;
sbit latch1=P2^3;
sbit latch2=P2^2;

unsigned char code weima[8]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f};
unsigned char code duanma[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};

unsigned char tempdata[8];
void delay(unsigned int t);
void display(unsigned char firstbit ,unsigned char num);

void main()
{
  unsigned int i;
  unsigned char num;
  while(1)
  {
i++;
if(i==500)
{
i=0;
num++;
if(num==10)
num=0;
}
  tempdata[0]=duanma[num%10];
  display(4,1);
  }

}


void delay(unsigned int t)
{
while(--t);
}

void display(unsigned char firstbit,unsigned char num)
{
unsigned char i;
for(i=0;i<num;i++)
{
DataPort=0;
  latch2=1;
  latch2=0;

DataPort=weima[i+firstbit];
  latch1=1;
  latch1=0;

  DataPort=tempdata[i];
latch2=1;
latch2=0;

delay(200);
}
}


编译时keil提示DataPort=0;DataPort=weima[i+firstbit]; DataPort=tempdata[i];附近有符号错误，求帮助？


[解决办法]
#define DataPort P0;

改成
#define DataPort P0

去掉分号
