Sounds good :)

Thanks! I will have a look. I'd like to implement opther features than
sound in the future, but for now that's fine.
The other hint I got was to use Randall Frank's routines at
www.rlkling.com/freeware/randallfrank.html.

If you haven't gotten around to installing IDL 5.4,
here is another alternative if you are running a
Windows machine. I got this little gem in a round-about
way (twice), but it comes originally from that Doyen
of Dirty IDL Code, Peter Mason, in Australia.
It's a hack, it's not well documented, and you didn't
get it from me. But it's fun, and it *does* work just
the way he said it would! :-)
It uses a DLL (winclip.dll) to read and execute WAV files,
calling the Windows sound routines directly, rather than
spawning a WAV player.
Here is a zip file. Extract it and read the directions
in the winclip.readme file. Follow them, and then type:
IDL> wavdemo
Get ready for a trip down memory lane! :-)
You can find the files here:
ftp://ftp.dfanning.com/pub/dfanning/outgoing/misc/wavdemo.zi p
Enjoy!

Strange. Now, on the same computer, the DOS window doesn't appear. But I
still see this:

That was my idea in the first place, but according to the help it works
with the Unix version only.

You mean, in 5.4, I _really_ do not get any nasty windows at all? It
looks so, I downloaded the whatsnew.pdf from RSINC's website, and voila,
there it is, the noshell keyword!
Okay, we install 5.4, and everything will be fine, I hope. Thanks!

Uh, how about the NOSHELL keyword to the SPAWN command.
Works in IDL 5.4. :-)
