點亮一小燈然后從左到右，從右到左亮滅，顯示SXLSD.C(20): error C141: syntax error near 'ADDR3'，望大佬們告知如何解決
單片機源程序如下:#include <reg52.h>

sbit LED = P0^0;
sbit ADDR0 = P1^0;
sbit ADDR1 = P1^1;
sbit ADDR2 = P1^2;
sbit ADDR3 = P1^3;
sbit ENLED = P1^4;

void main()
{
unsigned int i = 0;
unsigned char cnt = 0;
unsigned char sec = 0;
unsigned char dir = 0;
unsigned char shift = 0x01

ADDR3 = 1;
ENLED = 0;
ADDR2 = 1;
ADDR1 = 1;
ADDR0 = 0;
TMOD = 0x01;
TH0  = 0xB8;
TL0  = 0x00;
TR0  = 1;
while (1)
{
            if (TF0 == 1)
         {
               TF0 = 0;
               TH0 = 0xB8;
               TL0 = 0x00;
               cnt++;
               if(cnt >=100)
            {
                  cnt = 0;
                  LED = ~LED;
               }
                     {
                           P0 = ~shift;
                           for(i=0; i<30000; i++);
                              if (dir == 0)
                     {
                              shift = shift << 1;
                                 if ( shift == 0x80)
                        {
                              dir = 1;
                           }
                     }

                        else
                           {
                              shift = shift >> 1;
                              if (shift == 0x01)
                           {
                                    dir = 0;
                              }
                        }
                     }
            }
      }
}
