no, you can use CONTINUE only in loop. When you wont ignore exception,
just do nothing
For example, the following two fragments of code are equivalent:
   BEGIN       y := x / 0;   EXCEPTION       WHEN division_by_zero THEN           NULL;  -- ignore the error   END;
   BEGIN       y := x / 0;   EXCEPTION       WHEN division_by_zero THEN  -- ignore the error   END;
