function chilkatExample() {

    var success = false;

    var sb = new chilkat.StringBuilder();

    //  Load a file that contains this string:  0123456789ABCDEF
    success = sb.LoadFile("qa_data/txt/remove_chars.txt","utf-8");

    //  Return "56789A" from the string.
    //  if removeFlag is true, the returned string is also removed from the sb.
    var removeFlag = true;
    var result = sb.GetRange(5,6,removeFlag);

    console.log(result);
    console.log(sb.GetAsString());

    //  Output is: 
    //  
    //  56789A
    //  01234BCDEF
