Hi Yaosheng,

The function nf90_inquire was actually available as early as 
the 3.5.0 release (April 2000) and in all versions since then.  
It can be used to get the number of variables in the file as
follows:

  integer status, nvar

  status = nf90_inquire(ncid, nvariables = nvar)
  ! check status of call, if OK, then nvar has number of variables
  ! in file (or in the group if ncid is a group id)
  if (status .ne. nf90_noerr)
    ! handle error
