  !     Arguments :

  !     tapedef   :
  !     etatinit  :     = TRUE   , on ne  compare pas les valeurs des para- 
  !     -metres  du zoom  avec  celles lues sur le fichier start .

  LOGICAL, INTENT(IN) :: etatinit
  INTEGER, INTENT(IN) :: tapedef

  !   Declarations :

  include "comdissnew.h"
  include "iniprint.h"

  !   local:

  LOGICAL  fxyhypbb, ysinuss

  !  -------------------------------------------------------------------

  !       .........     Version  du 29/04/97       ..........

  !   Nouveaux parametres nitergdiv,nitergrot,niterh,tetagdiv,tetagrot,
  !      tetatemp   ajoutes  pour la dissipation   .

  !   Autre parametre ajoute en fin de liste de tapedef : ** fxyhypb ** 

  !  Si fxyhypb = .TRUE. , choix de la fonction a derivee tangente hyperb.
  !    Sinon , choix de fxynew  , a derivee sinusoidale  ..

  !   ......  etatinit = . TRUE. si defrun  est appele dans ETAT0_LMD  ou
  !         LIMIT_LMD  pour l'initialisation de start.dat (dic) et
  !                de limit.dat ( dic)                        ...........
  !           Sinon  etatinit = . FALSE .

  !   Donc etatinit = .F.  si on veut comparer les valeurs de  grossismx ,
  !    grossismy,clon,clat, fxyhypb  lues sur  le fichier  start  avec
  !   celles passees  par run.def ,  au debut du gcm, apres l'appel a 
  !    lectba .  
  !   Ces parmetres definissant entre autres la grille et doivent etre
  !   pareils et coherents , sinon il y aura  divergence du gcm .
