I use IDL on Windows at home and IDL on RS/6000 and VAX at work.
The good side:
I can write IDL stuff at home (including widgets) and
it all works the same. It's so nice to
be able to write platform-independant code
so easily! Even for mouse-clicking stuff...
The bad side:
I have just 8 MB of memory. IDL gets horrendously slow
on the PC with large images (>256x256)
On IDL on VAX and Unix, the terminal window shows
your current prompt and previous lines all
together in one window. For some reason,
they chose to have a one-line window for
your current command and a separate window
for previous commands. I don't like that.
However, using up-arrow still pulls back
your previous command, so it's not so bad.
Call_external stuff is less straightforward on DOS.

We have IDL for Windows running to at least two PCs here. One is a
notebook 486DX-33 with 8MB of memory and the other is a desktop PC. Both
run all the software from our workstations. We make sure that files that
need to be portable are written in XDR format. The only real limitation is
imposed by DOS and that is the 8 character limit on file names. Our Notebook
PC has a 64 level grey scale LCD display and I am not currently able to use
my own "color" table with it. A help,/device tells me that Windows has
reserved 16 of the 64 available colors and that the device has a STATIC color
map. It is very likely that I just have not figured out how to use the thing
properly yet. All in all, my experiences with IDL for Windows has been very
good. I would recommend it as a reliable piece of software and faithful to
form of the IDLs running on the other platforms. OH, a fast graphics
accelerator make a big difference and should be considered a must.

I use IDL for Windows 3.5.1 on a 486. I am able to do display very
I use IDL for Windows 3.5.1 on a 486. We also have IDL 3.0 on a
VAX/VMS and I find I can do more on the PC than on the VAX/VMS. A
word of advice, make sure you have 8MB of RAM - 16MB would be better.
This is one thing I like about IDL. The WIDGETs I write for the VAX
work on the PC without any changes.

We are running IDL on VAXes, Alpha's, and PC's. There has been virtually
no code changes made between the various systems (filenames, yes, with DOS'
8 and 3 character filename restriction). We needed to kick our RAM up to
32 megs in order to get the same performance as our VAXes.
