W3FI19

The W3FI19 routine finds the i,j coordinate point in a 65x65 grid-point
           array as being either inside, outside, or on the boundary
           of the 53X57 NMC Rectangle centered in the 65x65 array.

USAGE: CALL W3FI19 (I, J, NW)

   Input argument list:
      I   - COORDINATE IDENTIFICATION OF A POINT IN THE 65X65 ARRAY
      J   - COORDINATE IDENTIFICATION OF A POINT IN THE 65X65 ARRAY

   Output argument list:
      NW  - INTEGER RETURN CODE

   Exit states:
      NW = -1 POINT IS OUTSIDE THE RECTANGLE
      NW =  0 POINT IS ON THE RECTANGLE BOUNDARY
      NW = +1 POINT IS INSIDE THE RECTANGLE
