Sorry, I'm testy this morning. I'm trying to get something done
and I am plagued with e-mails from people not following through
on earlier suggestions. I'm implementing a "Don't Ask If You
Don't Want to Read the Answer" policy from now on. :-)

If you got this code from the ENVI manual, then I am going
to suggest (Heaven forbid!) the manual is wrong, cause that
code don't do what it is suppose to do!

A couple of judicious PRINT statements in or about the location
I suggestion yesterday should prove me right. :-)

Cheers,

David
