Neither. :-)

I suppose it did what I told it to do. It just ignores
what it doesn't understand, sort of like the dog here
at my feet.

My point was, I was trying to get it to do a particular
thing, and it wouldn't do it. It took me quite a few
minutes to realize the reason it wasn't working was
that I had accidentally transposed some letters in
a keyword. I know from experience that mis-spelled
commands that don't throw errors are some of the
HARDEST errors to track down in programs. These objects
are not going to make this kind of error any easier
to find.

Happy sleuthing!

It is a side effect of _EXTRA to be sure. But it
is also the reason _STRICT_EXTRA was invented.
Normally, by the time you get to the end of the
chain (do you go UP, or DOWN!?) you shouldn't have
any keywords left to process. If you do, something
is wrong.

My guess is that the "something wrong" message
is *extremely* long and potentially embarrassing,
since it has to come from deep in the bowels of
the object graphics system. But, I'm not sure
ignoring it is the best possible solution to the
problem.

Cheers,

David
