5.) Structures
  --------------
   You can add new Fields in your Structure without pressing the Insert-Key.
   (Just go with the Cursor to the last Record(Field) and automaticly
    there will be added a new Field)

   - With Input particular Field-Type's the Len will be choosed automaticly:
        >> Date -> "8" / Logical -> "1" /  Memo    -> "10"

   - For a Paradox-File you must consider follow rules:
        >> Len of a numeric Field: 15.4
        >> Memo-Fields and logical Fields are not alowed
