 * $Log: latsfort.c,v $
 * Revision 1.10  1996/12/12 18:39:44  fiorino
 * 961212
 *
 * Mike's changes to parm table
 * GraDS updated source
 * and improvements in GrADS output to handle yearly data and 365-day calendars
 * added gaprnt routine in latsfort.c to aid link with straight GraDS source
 *
 * Revision 1.9  1996/11/11 22:39:19  drach
 * - Added function to set the basetime (lats_basetime)
 *
 * Revision 1.8  1996/10/22 19:05:06  fiorino
 * latsgrib bug in .ctl creator
 *
 * Revision 1.7  1996/08/27 19:41:39  drach
 * - Handle Cray double/double precision mismatch
 *
 * Revision 1.6  1996/08/20 18:34:08  drach
 * - lats_create has a new argument: calendar
 * - lats_grid: longitude, latitude dimension vectors are now double
 *   precision (double, C).
 * - lats_vert_dim: vector of levels is now double precision (double,
 *   C). lats_vert_dim need not be called for single-value/surface
 *   dimensions, if defined in the parameter table. Multi-valued vertical
 *   dimensions, such as pressure levels, must be defined with
 *   lats_vert_dim.
 * - lats_var: set level ID to 0 for implicitly defined surface
 *   dimension.
 * - lats_write: level value is double precision (double, C).
 * - lats_parmtab: replaces routine lats_vartab.
 * - FORTRAN latserropt added: allows program to set error handling
 *   options.
 * - The parameter file format changed.
 *
 * Revision 1.5  1996/06/27 01:11:10  drach
 * - Check for POSIX compliance
 *
 * Revision 1.4  1996/05/25 00:27:49  drach
 * - Added tables for vertical dimension types, time statistics, originating
 *   centers, and quality control marks
 * - Modified signatures of lats_create and lats_vert_dim
 *
 * Revision 1.3  1996/05/10 22:44:40  drach
 * - Initial version before GRIB driver added:
 * - Made grids, vertical dimensions file-independent
 *
 * Revision 1.2  1996/05/04 01:11:11  drach
 * - Added name, units to lats_vert_dim
 * - Added missing data attribute (latsnc.c)
 *
 * Revision 1.1  1996/05/03 18:48:06  drach
 * - Initial repository version
