   4 ! This tests the fix for PR22010, where namelists were not being written to
   5 ! and read back from modules.  It checks that namelists from modules that are
   6 ! selected by an ONLY declaration work correctly, even when the variables in
   7 ! the namelist are not host associated. Note that renaming a namelist by USE
   8 ! association is not allowed by the standard and this is trapped in module.c.
