03/06/2016 01:00    3   6   2016    1   0

使用以下代码：

    program fecha
    implicit none
    integer, dimension(13):: dia, mes, ano, hora, minuto

    character*50 :: formato = '(11x,5x,1x,i1,1x,i1,1x,i4,1x,i1,1x,i2)'

    open (unit = 10, file = 'datos.txt')
    read(10,*)
    read(unit = 10, fmt = formato) dia, mes, ano, hora, minuto

    write(*,*) dia

    close(10)

    end program

为什么这段代码会这样读 'dia'：

 3           6        2016           0           0           3           6        2016           0           5           3           6        2016

（我知道它是怎么读的，但不知道为什么）

您需要在开头跳过两行并逐行读取值。

下面的例子是对你的程序稍作修改，运行流畅。

program fecha
  implicit none

  integer               :: i, iounit
  integer, parameter    :: n = 13
  integer, dimension(n) :: dia, mes, ano, hora, minuto

  open (newunit = iounit, file = 'datos.txt')
  read (iounit, *)
  read (iounit, *)

  do i = 1, n
    read (unit = iounit, fmt = '(16x, i5, i4, i7, 2i5)') dia(i), mes(i), ano(i), hora(i), minuto(i)
    print *, dia(i), mes(i), ano(i), hora(i), minuto(i)
  end do

  close (iounit)
end program

我的输出是

$ gfortran -g3 -Wall -fcheck=all a.f90 && ./a.out
           3           6        2016           0           0
           3           6        2016           0           5
           3           6        2016           0          10
           3           6        2016           0          15
           3           6        2016           0          20
           3           6        2016           0          25
           3           6        2016           0          30
           3           6        2016           0          35

           3           6        2016           0          50
           3           6        2016           0          55
           3           6        2016           1           0
