source: LMDZ5/trunk/libf/dyn3d/juldate.F @ 1934

Last change on this file since 1934 was 1930, checked in by lguez, 11 years ago

abort, dfloat and pause are not in the Fortran standard. Replaced
abort by abort_gcm and dfloat by dble. Note: I modified dyn3dpar files
that were identical to dyn3d modified files.
