[gradsusr] Logic error 8 in gxshad

[James T. Potemra]

Sudev:

This usually comes up when you have a point with an usually large 
number, e.g., a land value incorrectly set.  If you use "set gxout 
grfill" you might find which point (or points) are incorrect.  I tried 
to open this file via opendap, and it works ok:

sdfopen
