W3FI18

The W3FI18 routine finds the i,j coordinate point in a 65x65 grid-point
           array as being either inside, outside, or on the boundary
           of the NMC Octagon centered in the 65x65 array.

USAGE: CALL W3FI18 (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 OCTAGON
      NW =  0 POINT IS ON THE OCTAGON BOUNDARY
      NW = +1 POINT IS INSIDE THE OCTAGON
