If we have the following program:
OPEN(10,FILE='wup.in',STATUS='OLD')
CLOSE(10, STATUS='KEEP')
END
And a data file that is readable by everyone and writable by nobody:
$ ll wup.in
-r--r--r-- 1 sje other 0 Nov 24 08:43 wup.in
gfortran will fail on the open (because it tries to open for read & write),
other compilers will open for read-only if they cannot open for reading and
writing.
Opening for read-only is not required by the Fortran standard but it is how
most Fortran compilers (HP, Intel, g77) behave.
--
Summary: open call should open for read-only if open for
read/write fails.
