This compiles just fine (sorry about the crap formatting)

//Example 01 : Blinking LED 

# define LED 13  // LED connected to 
                //digital pin 13
                
void setup () 

{ 
 pinMode( LED, OUTPUT ) ;   // Sets the digital pin as output.
    digitalWrite( LED, HIGH);  //Turn the Led on
  
  delay(4000);               // Waits for 
  
  digitalWrite(LED, LOW);    // Turns led off
  
  delay (4000) ;             // Waits for  
  
   digitalWrite( LED, HIGH);  //Turn the Led on
   
   delay(500);               // Waits for 
 
 digitalWrite(LED, LOW);    // Turns led off 
 
  delay(500);               // Waits for
  
}

 void loop()
{ 

}
