source: NEMO/branches/2019/fix_sn_cfctl_ticket2328/src/ICE/icedyn_rhg.F90 @ 11872

Last change on this file since 11872 was 11872, checked in by acc, 4 years ago

Branch 2019/fix_sn_cfctl_ticket2328. See #2328. Replacement of ln_ctl and activation of full functionality with
sn_cfctl structure. These changes rename structure components l_mppout and l_mpptop as l_prtctl and l_prttrc
and introduce l_glochk to activate former ln_ctl code in stpctl.F90 to perform global location of min and max
checks. Also added is l_allon which can be used to activate all output (much like the former ln_ctl). If l_allon
is .false. then l_config decides whether or not the suboptions are used.

   sn_cfctl%l_glochk = .FALSE.    ! Range sanity checks are local (F) or global (T). Set T for debugging only
   sn_cfctl%l_allon  = .FALSE.    ! IF T activate all options. If F deactivate all unless l_config is T
   sn_cfctl%l_config = .TRUE.     ! IF .true. then control which reports are written with the remaining options

Note, these changes pass SETTE tests but all references to ln_ctl need to be removed from the sette scripts.
