resume on Exception

All, I know I can trap and exit on an exception but how can the program 
trap and  continue?

say I have

while <condition>
       update xxx where recnum ... ;
            if  any_exception then
                write any_exception & recnum to file and continue;
            end if;
end loop;

any examples of this logic?

Thanks!
Bob
