The Fortran standard says that if an @code{OPEN} statement is executed
|
||||
without an explicit @code{ACTION=} specifier, the default value is
|
||||
processor dependent. GNU Fortran behaves as follows:
|
||||
|
||||
@enumerate
|
||||
@item Attempt to open the file with @code{ACTION='READWRITE'}
|
||||
@item If that fails, try to open with @code{ACTION='READ'}
|
||||
@item If that fails, try to open with @code{ACTION='WRITE'}
|
||||
@item If that fails, generate an error
