Yes, exactly my plan, but at the moment it looks like I will have to
re-write GRIDDATA from scratch in order to understand it. :-(
I always get an ominous feeling when I've asked the same
question three or four times and get nothing but silence
back. An obvious topic for a Ph.D. thesis, is my first
thought. In this case, I was hoping the author might be
listening in and could tell us why he added the darn
SPHERE keyword in the first place. Surely he had something
other than confounding users in mind. :-)
Cheers,
David
