The hint about redirecting standard error as well will work; on the
other hand, maybe you should look into using the "Callable IDL" feature
present from v4.0 on up. Get the "IDL Advanced Development Guide" from
RSI for instructions in how to use it. One advantage of Callable IDL is
you won't need to use temporary files to retreive IDL output back into
your program; you access the variables directly.

I believe the startup message is sent to 'standard error', but the
'>' only redirects 'standard output'. Try redirecting both. Under
UNIX with the C-shell, try idl >& idl.txt
In fact, if you don't want the output at all, send it to the null
device by using idl >& /dev/null
Hope that helps

You need to redirect the standard error as well, as the intro
text goes there. Try fp=popen('idl >& idl.txt','w') or even
fp=popen('idl >& /dev/null','w').
