Well, of course it's a roast. These guys are suppose
to be *experts*. What else would it be!? :-)

Humm. That's the week of the State Tennis championships,
but we may be long gone by then. Let me check my calendar
and get back with you. Anyone else going to be in Boulder
that week?
Cheers,
David

I fear I may be a nominee for the "Wasted the most time of real IDL
expert programmers with stupid questions" award! Is the dinner a roast?
I will be in Boulder the week of October 8-11. Any chance the dinner is
that week? ;-)
Ken
P.S. I think the multiple, nested dialog boxes spawned by
DIALOG_PRINTERSETUP (4 deep at one point) may possibly be the most
confusing thing I have encountered in all of IDL. And that's saying
somethin'!

Ken,
As long as you made my book a required text for the course you are
teaching, then I have all the thanks I need.
Cheers,
Liam.

I've just been given word that Chairman Emeritus Coyote
wishes to present a "special recognition award" at this
year's IEPA Induction Dinner. I can't say more, but Ken
please keep your calendar clear. :-)

Bless you, Liam. Time for a footnote on p. 390 for those of us too dense to
realize that we need to use a color printer. ;-)

I get the same result in IDL 5.5 for IRIX when I use the default PRINTER
output device (Generic EPS). However if I select printer-specific output
using
result = dialog_printersetup()
and select the 'HP Color LaserJet PS on FILE:', then I get 24-bit color
output as expected. IDL remembers this setting via the
$HOME/.XprinterDefaults file, so the next time I start IDL, this printer
is the default when the PRINTER device is selected.
Cheers,
Liam.
