!**** *TRANS_INQ* - Extract information from the transform package

!     Purpose.
!     --------
!     Interface routine for extracting information from the T.P.

!**   Interface.
!     ----------
!     CALL TRANS_INQ(...)
!     Explicit arguments : All arguments are optional.
!     -------------------- 
!     KRESOL   - resolution tag for which info is required ,default is the
!                first defined resulution (input)

!                   SPECTRAL SPACE
!     KSPEC    - number of complex spectral coefficients on this PE
!     KSPEC2   - 2*KSPEC 
!     KSPEC2G  - global KSPEC2
!     KSPEC2MX - maximun KSPEC2 among all PEs
!     KNUMP    - Number of spectral waves handled by this PE
!     KGPTOT   - Total number of grid columns on this PE
!     KGPTOTG  - Total number of grid columns on the Globe
!     KGPTOTMX - Maximum number of grid columns on any of the PEs
!     KGPTOTL  - Number of grid columns one each PE (dimension N_REGIONS_NS:N_REGIONS_EW)
!     KMYMS    - This PEs spectral zonal wavenumbers
!     KASM0    - Address in a spectral array of (m, n=m)
!     KUMPP    - No. of wave numbers each wave set is responsible for
!     KPOSSP   - Defines partitioning of global spectral fields among PEs
!     KPTRMS   - Pointer to the first wave number of a given a-set
!     KALLMS   - Wave numbers for all wave-set concatenated together 
!                to give all wave numbers in wave-set order
!     KDIM0G   - Defines partitioning of global spectral fields among PEs

!                 GRIDPOINT SPACE                  
!     KFRSTLAT    - First latitude of each a-set in grid-point space
!     KLSTTLAT    - Last latitude of each a-set in grid-point space
!     KFRSTLOFF   - Offset for first lat of own a-set in grid-point space
!     KPTRLAT     - Pointer to the start of each latitude
!     KPTRFRSTLAT - Pointer to the first latitude of each a-set in 
!                   NSTA and NONL arrays
!     KPTRLSTLAT  - Pointer to the last latitude of each a-set in
!                   NSTA and NONL arrays
!     KPTRFLOFF   - Offset for pointer to the first latitude of own a-set
!                   NSTA and NONL arrays, i.e. nptrfrstlat(myseta)-1
!     KSTA        - Position of first grid column for the latitudes on a 
!                   processor. The information is available for all processors.
!                   The b-sets are distinguished by the last dimension of 
!                   nsta().The latitude band for each a-set is addressed by 
!                   nptrfrstlat(jaset),nptrlstlat(jaset), and 
!                   nptrfloff=nptrfrstlat(myseta) on this processors a-set.
!                   Each split latitude has two entries in nsta(,:) which 
!                   necessitates the rather complex addressing of nsta(,:)
!                   and the overdimensioning of nsta by N_REGIONS_NS.
!     KONL        - Number of grid columns for the latitudes on a processor.
!                   Similar to nsta() in data structure.
!     LDSPLITLAT  - TRUE if latitude is split in grid point space over 
!                   two a-sets

!                FOURIER SPACE
!     KULTPP   - number of latitudes for which each a-set is calculating 
!                the FFT's.
!     KPTRLS   - pointer to first global latitude of each a-set for which
!                it performs the Fourier calculations

!                 LEGENDRE
!     PMU      - sin(Gaussian latitudes)
!     PGW      - Gaussian weights
!     PRPNM    - Legendre polynomials
!     KLEI3    - First dimension of Legendre polynomials
!     KSPOLEGL - Second dimension of Legendre polynomials
!     KPMS     - Adress for legendre polynomial for given M (NSMAX)
