So now I renamed "bob" back to image and everything
compiles and runs perfectly.
Did I mention I *love* IDL 8.1. :-)

No problem doing this at the IDL command line:
IDL> W = WINDOW(DIMENSIONS=[800,800)
IDL> image = cgdemodata(7)
IDL> img = image(image,/current)
I don't know *what* is going on with my main-level
program. I know main-level programs don't really
work in IDL 8.1, so maybe it just has something to
do with that. Well, they work, just don't ever
make a programming error in one, or you are hosed
for that IDL session. I'm not sure they get
recompiled correctly. Maybe that is what happened.
Cheers,
David

Oh, for God's sake. Now it wants me to name
my image variable BOB again!!
IDL> help, image
IMAGE UNDEFINED = <Undefined>
IDL> help, /source
Compiled Procedures:
$MAIN$ C:\IDL\default\log_test2.pro
BUILD_TESTMODULE C:\Program Files\ITT\IDL\IDL81\external\dlm
\build_testmodule.pro
CGCONTROL C:\IDL\coyote\cgcontrol.pro
Compiled Functions:
IDL> .compile -v 'C:\IDL\default\log_test2.pro'
IMG = IMAGE(IMAGE,RGB_TABLE=RGB_TABLE,/CURRENT,LAYOUT=
[2,1,1],TITLE='Linear')
^
% Syntax error.
At: C:\IDL\default\log_test2.pro, Line 37
What the *hell* is going on here!? :-(
Cheers,
David
