[Dart-dev] [4310] DART/trunk/obs_def/DEFAULT_obs_def_mod.F90: Add a local 'fileformat' variable that is set by the utility subroutine

Revision: 4310
Author:   nancy
Date:     2010-03-10 13:37:50 -0700 (Wed, 10 Mar 2010)
Log Message:
-----------
Add a local 'fileformat' variable that is set by the utility subroutine
ascii_file_format, to make the changes to the obs_def mod completely
backwards compatible.  This local variable should be removed after the
next release and people should use 'fform' instead of 'fileformat' as the
last argument to any private read/write obs def routines.
