从文件结尾读取整数,"格式化数据传输完成缺失格式"

Question

我正在根据我的需求更新Fortran程序.该程序编译使用f95和gcc4.1.2版(我知道这是老了,但我不能更新).我想从文件中读取参数,我尝试通过

      inquire (file="resLast", exist=resExist)
      if (readStart.eq.1.and.resExist) then
         open (unit=18,file='resLast', status='old', action='read')
         read (18) startConf
         read (18) avlength, stdlength, avenergy
         read (18) i,h2(1)
         read (18) i,h2(2)
         read (18) i,h2(4)
         read (18) i,h2(5)
         read (18) i,h2(8)
         read (18) i,h2(9)
         read (18) i,h2(13)
         read (18) i,h2(16)
         read (18) i,h2(17)
         read (18) i,h2(18)
         read (18) i,h2(20)
         read (18) i,h2(25)
         read (18) i,h2(32)
         close (18)
      else
         startConf = 0
         do i=1,32
            h2(i)=0
            comh2(i)=0
         enddo
         avlength=0d0
         stdlength=0d0
         avenergy=0d0
      endif

输入文件看起来像

当我尝试运行时,我收到一个错误

Fortran runtime error: Missing format for FORMATTED data transfer
done

哪个指向第一read行.所述startConf variable, as well asi``是一个整数.其余变量是双精度.

我以前使用这种方法将数据读入整数(即使在相同的代码中)没有问题,我当前的错误在哪里？

由于您没有明确指定它,因此您的open语句假定formatted(文本)文件.从文本文件中读取时,您还必须提供一种格式:

read(18, *) i1

或者,如果您的文件是unformatted(二进制),请相应地打开您的文件:

 open (unit=18, file='resLast', status='old', action='read', form='unformatted')
