  !
  ! この手続きはコマンドライン引数のうち、*index* (*idx_given*)
  ! 番目の値を *value* (*result*) に返します。
  !
  ! *index* が引数の数よりも大きい場合、*value* には空文字
  ! が返ります。*index* が負の場合には、後方からの順番になります。
  ! すなわち、-1 ならば最後の引数が返ります。
  !
  ! ほとんどの処理系では Fortran90/95 規格外の <b>GETARGC()</b>
  ! 関数により実装されます。
  !
  ! gets the *index*th (*idx_given*th) commandline argument
  ! to *value* (*result*).
  !
  ! If *index* is more than the number of arguments,
  ! *value* will be filled with blank.
  ! If *index* is negative, *index*th argument in reverse
  ! is return to *value*. In other words, if *index* = -1,
  ! the last argument is returned.
  !
  ! Most typically, it is implemented by nonstandard built-in
  ! subroutine <b>GETARG()</b>.
