The PR_WIND function computes WIND from DRCT and SPED.  WIND 
            is in the form SSSDDD, where SSS is the speed and DDD
            is the direction.  SPED may be entered in meters/sec 
            or knots; DRCT is in degrees.


   Input parameters:
      DRCT            REAL            Wind direction in degrees
      SPED            REAL            Wind speed

   Output parameters:
      PR_WIND         REAL            Packed speed and direction
