6  C The five "public" routines supplied here are:  C--  File mdsio_gl.F: Routines to handle mid-level I/O interface.
7  C  C--   Contents
8  C MDSREADFIELD   - read model field from direct access global or tiled MDS file  C--   o MDSREADFIELD_3D_GL
9  C MDSWRITEFIELD  - write model field to direct access global or tiled MDS file  C--   o MDSWRITEFIELD_3D_GL
10  C MDSFINDUNIT    - returns an available (unused) I/O channel  C--   o MDSREADFIELD_2D_GL
11  C MDSREADVECTOR  - read vector from direct access global or tiled MDS file  C--   o MDSWRITEFIELD_2D_GL
12  C MDSWRITEVECTOR - write vector to direct access global or tiled MDS file

 C all other routines are "private" to these utilities and ought  
 C not be accessed directly from the main code.  
 C  
 C Created:  03/16/99 adcroft@mit.edu  
 C Modified: 03/23/99 adcroft@mit.edu  
 C           To work with multiple records  
 C Modified: 03/29/99 eckert@mit.edu  
 C           Added arbitrary vector capability  
 C Modified: 07/27/99 eckert@mit.edu  
 C           Customized for state estimation (--> active_file_control.F)  
 C           this relates only to *mdsreadvector* and *mdswritevector*  
 C Modified: 07/28/99 eckert@mit.edu  
 C           inserted calls to *print_message* and *print_error*  
 C  
 C To be modified to work with MITgcmuv message routines.
