**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
