Following Bruce's excellent posting, I'd like to point out a couple
of things.

The pricing for IDL and PV-WAVE was similar, when I looked about 8 months
ago. Both companies are in the Denver/Boulder CO area. Precision Visuals
licensed the technology, source, and manuals from RSI.

I believe that the newer versions of IDL and PV-WAVE work with X-windows,
and use names rather than numbers for parameters to some commands.

IDL supports more output devices, Grinnell image processor and Gould
image processor, for example.

The source for creating menus (using the PV-WAVE facility) is included.
It might be possible to write equivalent commands for IDL without a
lot of trouble.

For version of PV-WAVE that we have, one of the three manuals is identical
to one of the IDL manuals. The user library is identical to that supplied
with IDL.

So, the two products are quite similar in ancestry, capability, and
price.
