! Description: How to get an array of strings from a BUFR message.

integer :: ibufr
integer :: strsize
integer, parameter :: max_strsize = 20

! back from the call to codes_get_string_array

! Release memory associated with bufr handle
! ibufr won't be accessible after this
call codes_release(ibufr)
! Close file
