!
! This program creates a dataset that is one dimensional array of
! structures  {
!                 character*2
!                 integer
!                 double precision
!                 real
!                                   }
! Data is written and read back by fields.
!
! The following H5T interface functions are tested:
! h5tcopy_f, h5tset(get)_size_f, h5tcreate_f, h5tinsert_f,  h5tclose_f,
! h5tget_class_f, h5tget_member_name_f, h5tget_member_offset_f, h5tget_member_type_f,
