W3FT32

The W3FT32 routine interpolates scalar quantity from any 
           given NMC field (in Office Note 84) to any other field.
           The routine can do bilinearly or biquadratically and It
           will not rotate wind components.

USAGE:  CALL W3FT32(FIELD, MAPIN, DATA, MAPOUT, INTERP, IER)

   Input arguments:
      FIELD  - REAL*4    - TWO DIMENSIONAL ARRAY.
      MAPIN  - INTEGER*4 - NMC MAP NUMBER (K) FOR GIVEN INPUT FIELD.
      MAPOUT - INTEGER*4 - NMC MAP NUMBER (K) FOR WANTED OUTPUT FIELD.
      INTERP - INTEGER*4 - SET INTERPOLATION METHOD:
                           EQ 1 - LINEAR
                           NE 1 - BIQUADRATIC
 
   Output arguments:
      DATA - REAL*4 - ARRAY TO HOLD OUTPUT MAP (UNPACKED).
      IER - INTEGER*4 - COMPLETION CONDITION FLAG
 
   INPUT FILES:  NONE

   OUTPUT FILES: NONE
 
   RETURN CONDITIONS:
      IER = 0  -  NO DIFFICULTIES
            1  -  MAPIN NOT RECOGNIZED
            2  -  MAPOUT NOT RECOGNIZED
            3  -  PARTICULAR POLA MAPOUT NOT RECOGNIZED
            4  -  PARTICULAR LOLA MAPOUT NOT RECOGNIZED
            5  -  PARTICULAR LOLA MAPIN NOT RECOGNIZED
            6  -  PARTICULAR POLA MAPOUT NOT RECOGNIZED
            7  -  PARTICULAR LOLA MAPIN NOT RECOGNIZED
            8  -  PARTICULAR LOLA MAPOUT NOT RECOGNIZED
            THESE FLAGS ARE SET AT VARIOUS TEST LOCATIONS
