读取复杂输入数据时格式错误

Question

有一个包含行格式的文件：

  

string，char char integer

我尝试使用以下代码读取和存储在数组中：

module MyModyle

contains

subroutine ReadFileIntoArrays (filename, name_arr, kWh_arr)
    implicit none

    ! function parameters
    character (len = *), intent (in) :: filename
    character, dimension(:), intent (out) :: name_arr
    integer, dimension(:), intent (out) :: kWh_arr

    ! variables contained on a single line
    character (len = 1) :: first_name, second_name
    character (len = 20) :: surname
    integer :: consumption

    integer :: arr_index = 1, ios_status = 0, unit_number = 1
    character (len = 30) :: fullname

    open (unit = unit_number, file = filename, status = 'old', action = 'read')

    do
        ! read a line from the file
        read (unit_number, iostat = ios_status) surname, first_name, second_name, consumption

        ! check input validity
        if (ios_status > 0) then
            print *, "Wrong input format!"
            print *, surname, first_name, second_name, consumption
            exit
        else if (ios_status < 0) then ! end of file
            print *, "End of file reached."
            exit
        else ! populate arrays
            ! concatenate full name
            fullname = surname
            fullname = fullname//','
            fullname = fullname//first_name
            fullname = fullname//'.'
            fullname = fullname//second_name
            fullname = fullname//'.'

            name_arr(arr_index) = fullname
            kWh_arr(arr_index) = consumption

            arr_index = arr_index + 1
       end if
    end do

    close (unit_number)
end subroutine ReadFileIntoArrays

end module MyModule

! --------------------------------------------------------------- !

program MyMain
    use MyModule
    implicit none

    integer, dimension(10) :: consumption
    character, dimension(10) :: names
    character (11) :: filename = 'clients.txt'

    call ReadFileIntoArrays(filename, names, consumption)
end program MyMain

无济于事，我得到的只有：Wrong Input Format!。

文件阅读有什么问题，怎么做？

^{注意：经过一项研究，我发现只有简单文件阅读的帖子，主要涉及数字列。}
