        //****************************************************************************************
        // Example #1: 	InStrRev(stringcheck,stringmatch,start,comparemethod) - returns integer
        // of the position of the first occurrence of one string within another, starting from the
        // right side of the string.
        //
        // stringcheck - Required. String expression being searched.
        // stringmatch - Required. String expression being searched for.
        // start - Optional. Numeric expression setting the one-based starting position for each 
        // search, starting from the left side of the string. If Start is omitted then –1 is used, 
        // meaning the search begins at the last character position. Search then proceeds from right 
        // to left.
        // comparemethod - Optional - integer indicating binary or text
        //****************************************************************************************
 
        Console.WriteLine("Example #1: 	InStrRev(stringcheck,stringmatch,start,comparemethod) ");
 
        string strString1 = "Hello World";
 
 
        // Return Uppercase
        Console.WriteLine((strString1.LastIndexOf("l") + 1).ToString()); //Returns 10
 
 
        //write blank line to make output easier to read

        //Prevent console from closing before you press enter
