namelist_use_only.f90

linux下编程用 编译软件

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