<<Right since the Table_Of... had no cursor. But using cursor it is
possible
to have better performance. You can replace an element in-place.>>

   --    Inserts the couple (KEY, VALUE) into TABLE if there is no
entry with

   --  OVERVIEW:
   --    An entry having key KEY is searched for in TABLE. The given
   --  VALUE then replaces the previous one. No action is taken and no
