Traffic lights debugger

Use keil 4 to write the code to complete the crossing traffic lights debugging, code is as follows: 

#include <reg52.h>  
#include " delay.h " 
sbit W_E_R = P0 ^ 0 ; // red things 
sbit W_E_Y = P0 ^ 1 ; // something yellow 
the sbit W_E_G P0 ^ = 2 ; // things green 
the sbit N_S_R = P0 ^ . 3 ; // north-south red 
the sbit N_S_Y = P0 ^ . 4 ; // north-south yellow 
the sbit N_S_G = P0 ^ . 5 ; // north-south green

void main()    
{
    unsigned char I;
     // four red light crossing 
    W_E_R = 0 ;
    N_S_R = 0;
    delay1s();
    // traffic lights work cycle 
    the while ( 1 )
    {
        // something red light, green light north and south, 10s delay 
        W_E_R = 0 ;
        N_S_R = 1;
        N_S_G = 0;
        delay10s();
        // something flashing red light, yellow light flashing north and south, 3s delay 
        for (I = 0 ; I < . 3 ; I ++ )
        {
        W_E_R = 0 ;
        N_S_Y = 0;
        N_S_G = 1;
        delay1s();
        W_E_R = 1 ;
        N_S_Y = 1;
        delay1s();
        }        
        // something green light, red light north and south, 10s delay 

        W_E_G = 0 ;
        N_S_R = 0;
        delay10s();
        W_E_G = 1;
        N_S_R = . 1 ;
         // something flashing yellow, north-south red flash, 3s delay 
        for (I = 0 ; I < . 3 ; I ++ )
        {
            W_E_Y = 0;
            N_S_R = 0;
            delay1s();
            W_E_Y = 1;
            N_S_R = 1;
            delay1s();
        }
    }
