Fortran运行时错误：读取输入数据时文件结束

Question

I'm currently running a code and I'm always getting to the same end. I am trying to read an input file and it returns the error:

Fortran runtime error: End of file

In an other post they said to put in the iostat specifier so now my code looks like this:

INTEGER    :: m
INTEGER    :: st

Open(Unit = 13,action='read',file='Data_Inp.dat',status='old')
read (13,*, iostat = st) m
write (*,*) st
write (*,*) m

ALLOCATE(winkel(m),energie(m))

Do i = 1,m
  read(13,*),winkel(i),energie(i)
End Do

And the input file looks like this:

12
-17.83 -0.019386527878
-15.83 -0.020125057233
-12.83 -0.020653853148
-11.83 -0.020840036028
-9.83 -0.020974157405
-8.83 -0.021056401707
-6.83 -0.021065517811
-5.83 -0.020992571816
-4.83 -0.020867828448
-1.83 -0.02069158012

Now the terminal prints a -1 for iostat and a constantly changing number for m.

Answer 1

如果第一个读取命令引起错误，请检查输入文件中“ 12”之前或之后的多余字符，尤其是在一个平台（Windows？）上创建并在另一个平台（Linux？Mac？）上使用的情况下。
