     16Step 1: New interface to read namelists 
     17A new way to read namelist variables has been implemented. Instead of reading one namelist with a sequence like: 
     18 
     19{{{ 
     20      REWIND ( numnam ) 
     21      READ( numnam, namctl ) 
     22}}} 
     23the new interface looks like: 
     24 
     25{{{ 
     26      REWIND( numnam_ref )              ! Namelist namctl in reference namelist : Control prints & Benchmark 
     27      READ  ( numnam_ref, namctl, IOSTAT = ios, ERR = 901 ) 
     28901   IF( ios /= 0 ) CALL ctl_nam ( ios , 'namctl in reference namelist', lwp ) 
     29 
     30      REWIND( numnam_cfg )              ! Namelist namctl in confguration namelist : Control prints & Benchmark 
     31      READ  ( numnam_cfg, namctl, IOSTAT = ios, ERR = 902 ) 
     32902   IF( ios /= 0 ) CALL ctl_nam ( ios , 'namctl in configuration namelist', lwp ) 
     33      WRITE( numond, namctl ) 
     34 
     35}}} 
     36'''More details:''' 
     37 
     38 
     39'''To read the namelist variables:''' 
     40- a reference namelist is read first (this namelist_ref file is unique, located in CONFIG/SHARED directory, contains all the variables and is in read-only mode) 
     41- a configuration namelist is read afterwards, only to overwrite the defaults values read from the reference namelist (this one is specific, short and located in EXP00) 
     42 
     43'''To deal with errors while reading:''' 
     44A new ctl_nam subroutine has been implemented in lib_mpp.F90 to deal with erros and print them in ocean.output if needed 
     45 
     46'''To check the values of namelist variables''' 
     47A new output.namelist, output_namelist_ice... output files are created: each time a namelist group_name is read, is it wirttin (ascii) in the output_namelist corresponding file, so that this file, created at execution time, contains all namelist avriables and their values as taken in account during the simulation.

     49Done in the source code and in all EXP00 reference configurations, and in CONFIG/SHARED, see revision 3875
