On Windows, if a file is open in Excel, one cannot write to it in a Fortran
program. So if "junk.csv" is opened in Excel and I compile and run the code
program xopen
! check what happens when program tries to open file already open
implicit none
integer, parameter :: iu = 20
character (len=*), parameter :: xfile="junk.csv"
open (unit=iu,file=xfile,action="write",status="replace")
end program xopen
gfortran
Target: i386-pc-mingw32

Thread model: win32
gcc version 4.3.0 20061021 (experimental)
says
At line 6 of file xopen_error.f90
Fortran runtime error: Permission denied
I'd like it to say that file "junk.csv" could not be opened, to make debugging
easier for the user. For example, Intel Visual Fortran says
forrtl: The process cannot access the file because it is being used by another
process.
forrtl: severe (30): open failure, unit 20, file U:\vrao\fortran\junk.csv

I believe this has been fixed already by PR30005 since December 5.
At least my gfortran prints:
At line 6 of file foo.f90
Fortran runtime error: Permission denied trying to open file 'junk.csv'

Correct. The fix isn't in 4.2 though (which is what I tried :-)
Closing as a duplicate of 30005.
