Ken,
Thanks very much. A colleague is bringing up this issue with RSI, and we'll
let you (all) know of any positive developments. I wonder if IDL 5.5 also
kills the redirect.
Your work-around is, essentially, to write the program's output to a file. I'd
thought of doing so, but I don't want to go that route.

Hi David,
Please see my earlier post (under you previous title). This is something
new in 5.4, and is under Sun, and Linux.
I also posted my work-around (its not good enough to be a "fix").
-k.

Here's the scoop:
RSI says that it (the loss of redirected output) is a known bug in IDL 5.4 and is
fixed in IDL 5.5. The fix for IDL 5.4 is to use "flush":
flush, -1 ; Flush the output buffer so that informational messages can be written
flush, -2 ; Flush the output buffer so that stderr can be written
So the code below now works. That is, the output file now does in fact contain the
program's output.
$ cat runidl
print, 'Hello world'
flush, -1
flush, -2
exit
$ idl runidl > runidl.out
$ cat runidl.out
Hello world
Thanks to all who responded.
