PV~Wave and IDL have a common root - the creators of IDL.
PV started out marketing IDL as PV~WAVE, but then excercised
an option to buy the source code rights and split off.
Since then, both PV~WAVE and IDL have been enhanced, but
in different directions. Both have X-windows-type
widget stuff (but the details are different), and PV~WAVE
has a widget-only version (point and click). I think
PV~WAVE has the option of buying IMSL subroutines as well.
We use IDL on Vax, RS/6000 (unix), and PC (Windows). We can
pop routines around between all three with no hitches (well,
there are some kinks to linking in C code).

No longer. Unless RSI has changed their minds over the last few weeks, they
are now charging for upgrades starting with IDL v3.1.
Upgrades are free if you pay the maintenence fee, which is in the $200+ per
node per year range (much more if you have a VAX cluster).

My job is to stare into space.
Don't hold anyone responsible for what I say. I'm on my coffee break.

1. No--it is a superset of old version of IDL.
2. For the most part they are the same. IDL has more functions to read
and write images, and it has a map generator. I try to use that which
is common to both, since I use each on different machines.
Also--you can update IDL for free. And you can get a trial copy of IDL
(which only runs for 7 minutes at a time and can't output any files
except postscript) by anonymous FTP of pub/idl/README from 128.138.240.1.
On the other hand PW Wave runs a little faster (I think) and it may have
fixed a some bugs.
