Directly-mode

  The directly-mode is to add or delete data. With Alt+D you put
  directly-mode on and off.

  When mode is ON, you can:

        - With the insert-key  you insert a new record at the point you
          are standing. All the other records will move forwards.
        - With Delete-key you delete definitliy record you are standing at.

  If mode=OFF, the following is valid:

        - With Insert-key the new data will be added at the end of the
          data a empty record.
        - With Delete-key , the data will only be marked as 'deleted', but
          will not be delete.

  If Directly-mode is ON , an 'M' will be on the lower side of the
  screen.
  If you are in Share-mode (Network) you can using this function not
  full, because for the insert-function must be the full data shared
  and by delete-function it is not possible to pack the data.
