JD Smith <jdsmith@astrosun.tn.cornell.edu> has either gone completely
bonkers or Ithaca has turned into the Boulder of the East. In
either case, his story gets curiouser and curiouser.
But...I'm pretty sure I know what is going on. :-)

Right-oh. Get rid of them. Completely. Do away with them. This is
the thing that is frying your goose (er, something!).
No way you should have TVLCT, r, g, b, /Get *AND* a common
block. Stuff and nonsense. One or the other, my man. And I say,
chuck the block.
All this copying to and fro is doing you in. Putting you under, so
to speak. Casting stars in your eyes, if you catch my drift. Colors
floating about.
You want colors, go *get* them:
TVLCT, r, g, b, /GET
You want to load them, load them:
TVLCT, r, g, b
Or, what I prefer:
LOADCT, 5, NColors=200, Bottom=10 ; or whatever,
But don't be messin' around with no *common* block. No, sir, you're
better than that! Steer clear of that riff-raft.

Do you believe I am not only reading this, but responding after a six-pack
and working 14 hours on my IDL manual today. I have to *seriously* get a life!

Yes, indeed. And this one has cheered me up more than most. :-)
I'll buy the beer next time I see you , JD!
Cheers!
