Something like that, yes. :-)
It is interesting to me, because when I finished IDL
Programming Techniques I was so tired of reading the
darn thing I never wanted to read it again, ever!
I feel differently about this book. In fact, I can't
wait until this inevitable marketing phase is over so I
can get onto writing the next one! I have ta least three
more books I want to write. But, *everything* in my plan
depends on generating enough income to justify it. No
income, and I'm afraid I'll have to go back to working
for a living. :-(
So, yes, buy those books. My current plan is to end
the pre-publication sale tomorrow and start opening this
up to the world outside the IDL newsgroup. People who
buy now will be judged favorably in the future. :-)
Cheers,
David

So whatcher sayin' is that the more copies of this book you sell now,
the faster you can go on a hermitic voyage to write CGS v2. I get it.
Makes total sense. We'll have you off in no time! :-)
