what is purpose of this program???

anyway here you go, you need to initialize variables Dot1 and Dot2, as program will try to increase value of Dot2 just few line down and then compare to Dot1

int Dots1 = 0;	// missing initialization
	int Dots2 = 0;	// missing initialization
	
	//Calculate Dots
	Dots1 = TotalDots - 1 - Word1.length() - Word2.length();
	
	//Dots Results
	String Results = "";
	
	do 
	{
		Results += (Dots);
		Dots2 ++;
	}while (Dots2 <= Dots1);

Thanks Peter,
Purpose of program: could be used as part of an index for book.
