Unpaired / in namelists can cause issues

Some of the namelists in the current trunk have an extra / which is not paired to and opening ampersand. E.g.:

&namtrd        !   trend diagnostics                                    (default: OFF)
&namhsb        !  Heat and salt budgets                                 (default: OFF)

This can cause issues. In tests on one system the namelist processing was stopped at this line (without error) meaning that subsequent settings were not used. Both the cause and effect can be difficult to detect so extra care is advised when uploading changes to namelists.


A simple script such as this:

for d in cfgs tests
  cd $d
  for nml in `find ./ -name '*namelist_*'`
    namp=$(grep -c -e '^&' $nml)
    nsla=$(grep -c -e'^/' $nml)
    if test $namp -ne $nsla ; then
     echo 'irregularity ('$namp' to '$nsla') in '$d${nml:1}
  cd ../

run in the top level directory has identified those namelists that needed changing


Exercise caution with changes to namelists and run this script before any releases
