guide_loc_mod.F90 @ 4270

Last change on this file since 4270 was 3803, checked in by Ehouarn Millour, 4 years ago
Make dynamics restart.nc file be in "64-bit offset" mode to enable generating large files. While at it also enforce this for limit.nc, guide_ins.nc and grilles_gcm.nc generated by the model. EM
