    ! 無効な変数名のチェック
    !
    ! HstNmlInfoSetValidName によって, 有効性を設定されていない変数が
    ! ある場合, 
    ! *invalid* に .true. を返し, *names* には無効な
    ! 変数名をカンマで区切った文字列を返します. 
    ! 
    ! なお, 与えられた *gthstnml* が HstNmlInfoCreate によって初期設定
    ! されていない場合, プログラムはエラーを発生させます. 
    !
    ! Check invalid variable names
    ! 
    ! If variable names that are not set validation by 
    ! "HstNmlInfoSetValidName" are exist, 
    ! .true. is set to *invalid*, and invalid variable names
    ! are joined with comma, and set to *names*. 
    !
    ! If *gthstnml* is not initialized by "HstNmlInfoCreate" yet, 
    ! error is occurred.
