It all depends on what you mean by
finishing off the particular element. Do you mean that you are processing an element and now the program is interrupted, but you still want to continue with the same process?? This could be very dangerous, and should only be attemted if you know exactly where your program was when it was intterrupted. This means that you will have to keep track of every step in the processing of that element.
Please explain more clearly what your intentions are. And how you process your elements.
