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!

I've made some edits to the QHULL reference page to clarify
which arguments and keywords are input vs. output variables.
The keyword descriptions did seem a bit cryptic on that score.
The Syntax section did at least note that the SPHERE keyword
is to be set equal to a variable... ;-)
It is, I hope, better now. Updates will appear in the next
release of the help.
As Jim Pendleton notes elsewhere in this thread, the IDL 7.0
help system has a handy link at the bottom of each topic that
lets you send mail directly to us in the IDL documentation
group. We appreciate any and all suggestions...

Ditto!
