<p style="margin-top:0;margin-bottom:0">I have reviewed the man page for "set defval" (<a href="http://cola.gmu.edu/grads/gadoc/gradcomdsetdefval.html" class="OWAAutoLink" id="LPlnk669401" previewremoved="true">http://cola.gmu.edu/grads/gadoc/gradcomdsetdefval.html</a>)
and it appears that my coding is correct but, I am not seeing the results that I was expecting, i.e. a change in the grid values where the ASOS stations are.</p>
