As long as we are making documentation requests, could
I please request a clarification on the QHULL SPHERE
keyword documentation. I don't know how many collective
man-months of work are lost by calling QHULL like this:

QHULL, lon, lat, tri, /DELAUNAY, /SPHERE

but I'm sure it is substantial. What in the world do you
do with this kind of an error message?

% QHULL: Expression must be named variable in this context: <INT
( 1)>.

The proper way to call QHULL is like this:

QHULL, lon, lat, tri, /DELAUNAY, SPHERE=s

Some indication of which positional and keyword parameters
are input and which are output would also be helpful. :-)

Thanks,

David

P.S. Nice surprise to see you at lunch today!
