@end enumerate

@section File operations on symbolic links
@cindex file, symbolic link
This section documents the behavior of GNU Fortran for file operations on
symbolic links, on systems that support them.
@itemize
@item Results of INQUIRE statements of the ``inquire by file'' form will
relate to the target of the symbolic link. For example,
@code{INQUIRE(FILE="foo",EXIST=ex)} will set @var{ex} to @var{.true.} if
@var{foo} is a symbolic link pointing to an existing file, and @var{.false.}
if @var{foo} points to an non-existing file (``dangling'' symbolic link).
@item Using the @code{OPEN} statement with a @code{STATUS="NEW"} specifier
on a symbolic link will result in an error condition, whether the symbolic
link points to an existing target or is dangling.
@item If a symbolic link was connected, using the @code{CLOSE} statement
with a @code{STATUS="DELETE"} specifier will cause the symbolic link itself
to be deleted, not its target.
