IDL 5.0 utilizes OpenGL when it is available, including Linux running
on an Intel system and on Windows (95,NT). The new Sparc Ultra's
have OpenGL, as do SGI's. See the January '97 Research Systems
Newsletter for more info.

The only advantage I can see to getting the Windows version is that you
will not have to reboot when you want to work with Word or Powerpoint.
However, Windows cannot read Linux disk file systems. The option would
be to have Linux write to the Windows/DOS partition when it outputs the
files. I think Linux can now not only write to FAT disks but also FAT32
and even NTFS (but I'm not 100% sure of that).
There is a major disadvantage with the Win32s version of IDL4.0+ and
that
is it does NOT properly handle long filenames. If a routine is in a
file
with a non-8.3 name IDL will NOT be able to access it. This makes
collaborating with UNIX IDL programmers a bit of a hassle. RSI claims
that
the new 5.0 for Windows will have full long filename support.

Hi!
I`ve learned IDL on SunOS. When I used it the first time with
windows... well, it was horrible, as many things that I was used to
didn't work like in Unix. After all, I ended up doing my image
processing on a 12MB Laptop under Linux....
Concerning the Linux-Windows file conversion: The only difference (I
believe) is the different treatment of End-of-line and End-of-file in
text files. But there are tools to do the necessary conversion (recode
is one of them).
For graphics files, there should be no problem at all (gif, tiff etc.)
Just one remark (if you are not aware of the problem): There's a
difference in endianess between PC and Sun (if you intend to use the
data on both architectures). PC uses little-endian, so you'll have to
byte-swap your data (unless you write in XDR-Format).
But that is valid for both IDL on Linux and Win.

One thing you might also want to consider is using WABI for linux. We
just
installed it, and it allows you to run word and powerpoint from within
Linux.
It costs $200.
We have been using idl for linux, and the only real problems specific to
Linux
I have encountered have been with the X-server, however I believe that
Xi now
has a X-windows server which supports 8 bit psuedo-color when running as
a 24 bit
color, which ease some of the problems.
One questions I'm not sure of though. We have an OpenGL server on our
machine
(i.e. not Mesa). Does IDL 5.0 use the OpenGL server if its available or
does it
always use Mesa? OpenGL is significantly faster in rendering.
