A sequence identifier ($Seq[x] x=1,..,n) created under
     a file identifier ($File[x] x=1,..,n) cannot be deleted.
    The sequence identifier is moved to the temporary save sequence.
    It also moves down the file identifier from the temporary save sequence.
   The sequence identifier of the temporary save sequence can be deleted here
   (1) Move to temporary save sequence
         Select the sequence identifier you want to temporarily save from
        the sequence identifiers below the file identifier.

     Click Menu -> "Save Output Sequence Identifier"
       
      Or, right-click the selected sequence identifiers and
      click "Save Sequence Identifiers".
       
      Go to the temporary save sequence.
       
     The sequence identifier $Seq[1] is moved from under the file identifier to
     the temporary save sequence.
 
     (2) Move from temporary save sequence to file identifier
        If you want to move the sequence identifier in the temporarily saved sequence to
        the direction of the file identifier, select the position
        (file identifier or sequence identifier)
        to which you want to move the file identifier.
        The saved sequence identifier moves below the desired position.
       (If there are more than one in the lower position, move to the last position)
       

      The figure above shows the case where the temporary save sequence $Seq[1] is
      moved below the file identifier $File[1].
      To move, select the temporary save sequence identifier you want to move,
      and select the file identifier or sequence identifier to move.

       Click Menu -> "Move Sequence Identifier to File Identifier" under Output.
      
       Or, right-click the selected sequence identifiers and
       click "Move Sequence Identifier to File Identifier".
      
       Go to File Identifier
        
       Moves $Seq[1] to the bottom end of file identifier $File[1].

    (3) Deletion of temporary save sequence
        Select the temporary save sequence you want to delete.

      Click Menu -> "Remove Sequence Identifier" under Output
       
      Or, right-click the selected sequence identifier and
      click "Delete Sequence Identifier".
                     
       The sequence identifier is removed.
