David,
this is one of the ten items we should never do.
1. DON'T USE !ORDER=1
2. Make DAMN sure what you pass to WHERE is a scalar and not an array.
ASSUME NOTHING!!!!
....
While watching the google archive I recognized you have about 9.480 postings
till now sent to this newsgroup. What did you do by reaching 10.000?
cheers

Oh, my God, it's embarrassing. And I see that only a third
of them have any kind of IDL content. :-(
I think when I hit 10,000 I'll have a big retirement party. :-)
Cheers,
David
