    //  The GetBefore method returns the contents of the string up to but not including
    //  the marker string.  If the remove flag is true, then both the returned string AND
    //  the marker are removed.

    String marker = ".";
    String substr = sb.getBefore(marker,removeFlag);
    System.out.println("substr = " + substr);

    System.out.println("sb contains: " + sb.getAsString());

    //  Output:

    //  sb contains: chilkatsoft.com

    //  If the marker is not found, and the removeFlag is true,
    //  then the entire string is returned and the sb is cleared.
    //  For example:
    sb.Clear();
    sb.Append("111--222--333--444");
    marker = "--";

        System.out.println("substr = " + substr + ", sb contains: " + sb.getAsString());
        }

    //  Output is:
    //  substr = 111, sb contains: 222--333--444
    //  substr = 222, sb contains: 333--444
    //  substr = 333, sb contains: 444
    //  substr = 444, sb contains:
