        // If the marker is not found, and the removeFlag is true,
        // then the entire string is returned and the sb is cleared.

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