  ! 文字列変数の日時単位 *unit_str* を整数型変数の日時単位
  ! *unit_sym* に変換します. 
  ! *unit_str* として有効な文字列は以下の通りです. 
  !
  ! dc_calendar_types#UNIT_SEC          :: 秒の単位
  ! dc_calendar_types#UNIT_MIN          :: 分の単位
  ! dc_calendar_types#UNIT_HOUR         :: 時間の単位
  ! dc_calendar_types#UNIT_DAY          :: 日の単位
  ! dc_calendar_types#UNIT_MONTH        :: 月の単位
  ! dc_calendar_types#UNIT_YEAR         :: 年の単位
  ! 
  ! 有効な文字列が与えられた場合, *uni_sym* に以下の変数に相当する
  ! 整数が返ります. 
  !
  ! dc_calendar_types#UNIT_SYMBOL_SEC          :: 秒の単位
  ! dc_calendar_types#UNIT_SYMBOL_MIN          :: 分の単位
  ! dc_calendar_types#UNIT_SYMBOL_HOUR         :: 時間の単位
  ! dc_calendar_types#UNIT_SYMBOL_DAY          :: 日の単位
  ! dc_calendar_types#UNIT_SYMBOL_MONTH        :: 月の単位
  ! dc_calendar_types#UNIT_SYMBOL_YEAR         :: 年の単位
  !
  ! 無効な値が与えられた場合, エラーを生じます. 
  !
  ! Parse a character variable of units of date *unit_str*, and 
  ! return an integer variable of units of date *unit_sym*. 
  ! Valid strings as *unit_str* are as follows. 
  !
  ! dc_calendar_types#UNIT_SEC          :: Units of second
  ! dc_calendar_types#UNIT_MIN          :: Units of minute
  ! dc_calendar_types#UNIT_HOUR         :: Units of hour
  ! dc_calendar_types#UNIT_DAY          :: Units of day
  ! dc_calendar_types#UNIT_MONTH        :: Units of month
  ! dc_calendar_types#UNIT_YEAR         :: Units of year
  !
  ! When a valid string is specified, an integer corresponding 
  ! one of following variables is returned to *unit_sym*. 
  !
  ! dc_calendar_types#UNIT_SYMBOL_SEC          :: Units of second
  ! dc_calendar_types#UNIT_SYMBOL_MIN          :: Units of minute
  ! dc_calendar_types#UNIT_SYMBOL_HOUR         :: Units of hour
  ! dc_calendar_types#UNIT_SYMBOL_DAY          :: Units of day
  ! dc_calendar_types#UNIT_SYMBOL_MONTH        :: Units of month
  ! dc_calendar_types#UNIT_SYMBOL_YEAR         :: Units of year
  !
  ! If an invalid string is specified an error is caused.
