Return statement
In BI# functions may return a value when they use the keyword 
		  return: 
		
int Avg(int a, int b)
{ 
	return (a + b) / 2; 
} 
		       The returned value must be of the same type as the function's type. In
		  the example above the function 
		  Avg is of type 
		  int and the 
		  return expression is of type 
		  int, too. The example also works if the
		  function type is 
		  double. In this case BI# converts the 
		  int expression automatically. 
		
You can also use the 
		  return statement to leave a 
		  void function prematurely: 
		
void PrintMessage(string message, int threshold)
{ 
	if (threshold < 5)
	{ 
		return; 
	}
	WriteLine(message);
}
