Does gfortran has issue working with the file as I/P and O/P ??

It repeatedly shows
Fortran runtime error: Bad real number in item 1 of list input

I tried running the programme in silverfrost and it works fine.
Should I download g95 to fix the problem?

gfortran should work well. What is the offending line of code? And what is the input file (binary or ascii text)? Please, show us the code, so that we can have a clue.

program work_file
implicit none
double precision ::x,y
integer::ln
open(8,file="w1.txt")
open(9,file="w2.txt")
do ln=1,10
read (8,*)x
y=x*10
write(9,'(2f10.2)')x,y
enddo
close(8)
close(9)
end program work_file

As I said it works well with the Silverfrost in Win platform.

What is the content of w1.txt? I would like to test the program on my machine, if you don't mind.

It worked. I guess the program which created "w1.txt" created the problem. Well thanks for your reply.
