sw_aeroAR4.F90 @ 1306

Last change on this file since 1306 was 1299, checked in by Laurent Fairhead, 15 years ago

Nettoyage general pour se rapprocher des normes et éviter des erreurs a la
compilation:

tous les FLOAT() sont remplacés par des REAL()
tous les STOP dans phylmd sont remplacés par des appels à abort_gcm
le common control défini dans le fichier control.h est remplacé par le module control_mod pour éviter des messages sur l'alignement des variables dans les déclarations
des $Header$ remplacés par des $Id$ pour svn

Quelques remplacements à faire ont pu m'échapper

General cleanup of the code to try and adhere to norms and to prevent some
compilation errors:

all FLOAT() instructions have been replaced by REAL() instructions
all STOP instructions in phylmd have been replaced by calls to abort_gcm
the common block control defined in the control.h file has been replaced by the control_mod to prevent compilation warnings on the alignement of declared variables
$Header$ replaced by $Id$ for svn

Some changes which should have been made might have escaped me
