Last change on this file since 1279 was 1279, checked in by Laurent Fairhead, 14 years ago

Merged LMDZ4-dev branch changes r1241:1278 into the trunk
Running trunk and LMDZ4-dev in LMDZOR configuration on local
machine (sequential) and SX8 (4-proc) yields identical results
(restart and restartphy are identical binarily)
Log history from r1241 to r1278 is available by switching to

7     ! "nf95_gw_var" stands for "NetCDF 1995 get whole variable".
8     ! These procedures read a whole NetCDF variable (coordinate or
9     ! primary) into an array.
10     ! The difference between the procedures is the rank of the array
11     ! and the type of Fortran values.
12     ! The procedures do not check the type of the NetCDF variable.
