Yes, but there is educational pricing and then there is educational
pricing.
Case in point, AutoCAD normally costs in the vicinity of $3K.
Educational
versions with full functionality can be had for $175! It does make
sense to
let the "kids" learn it at little or no cost and then they'll convince
their
employers to buy it at "retail" when they graduate and get jobs. Now I
have
always maintained that is also makes sense to have a similar discount
for
users to have a home copy. While this has been offered to folks who run
Linux (and perhaps more recently for PCs) it was still price, in my
estimation,
too high at $500. If it were $200, I'd buy it for home.
Just another $0.02,
JMZ

I do not believe that CALL_EXTERNAL is available in demo mode.

So, even if RSI closes the HDF loophole, the clever user simply
develops a routine to read back data *from* a PS-file, and voila, there
you have a fully-functional 7-minute version of IDL 8-)

The last IDL newsletter I saw (volume 6 no. 1) mentioned the availablility of
educational pricing. It expired on June 30th according to the notice, but
perhaps they'll extend this pricing again. For info they list Donna Carr at
donna@rsinc.com or 303.786.9900 by phone. No actual price is listed in the
letter.

Is CALL_EXTERNAL still available in the demo mode (I forget!)
If so, there's another way to write out data!

RSI makes IDL available via their FTP site at ftp://ftp.rsinc.com
Windows, Linux, and Macintosh versions are available for
lower end hardware.
The downloadable versions are fully functional, except for the
following important restrictions:
(1) IDL runs for 7 minutes, then quits.
(2) You cannot write/save anything to disk within IDL.
However it's not as bad as it sounds. I have used IDL in demo mode
more than once to get work done when a licensed version was not
available due to hardware problems, and my experience has been that
(1) Because you can only run IDL for 7 minutes, you quickly learn
to write IDL procedures - this is a good thing in my opinion!
(2) There are a couple of formats that you *can* save to disk while
in demo mode. One of them is Postscript. The other is HDF (SDS mode
anyway). You can do a lot with just these two output formats - maybe
there are others that I don't know about - I discovered these by
accident.
So give the IDL demo version a try. You might find you can do a lot
with it.
Cheers,
Liam.
