Many thanks. I find this works without the SpecialCoor command as well.

<pre wrap="">This is good, now can I ask one more question: How can I graph say,
y=log x, and shade the region between x=3 and x=4, but without
evaluating log 3 and log 4 to give the y-coordinates of the lines x=3
and x=4. Is there a way to graph the boundary lines of the shaded region
from (3,0) to (3, the point on log x) and (4,0) to (4, the point on log x).
