Capturing screen output [message #28088]

I'm running IDL 5.4 on a Sun.

I've got a file, cpsub1, which looks like this:

$ cat cpsub1
echo "computePPP, /batch, inputfile='abc.hdf'" | idl

If I run it by simply typing cpsub1 at the command line, all of the IDL
messages and PRINT statement outputs are sent to the screen:

$ cpsub1
% Compiled module: MODULE1
% Compiled module: MODULE2
% Compiled module: MODULE3
Entered main routine...
Computing the power...
Done.
$

I'd like to capture that information in a log file, so I tried
redirecting standard output, like this:

$ cat cpsub2
echo "computePPP, /batch, inputfile='abc.hdf'" | idl > cplog2

$ cpsub2
% Compiled module: MODULE1
% Compiled module: MODULE2
% Compiled module: MODULE3
$

As you can see, now only the IDL messages are written to the screen.
But the PRINT statement outputs aren't sent to the log file! Upon
completion, cplog2 is a 0-byte file.

Then I tried redirecting both standard output and standard error:

$ cat cpsub3
echo "computePPP, /batch, inputfile='abc.hdf'" | idl > cplog3 2>&1
$ cpsub3
$

Now nothing is written to the screen. But neither is it going to the
log file! Upon completion, cplog3 is a 0-byte file.

Can anyone help me capture the IDL messages and the PRINT statement
output into a file? I'm running my code in this odd manner because
ultimately I want to run the job in batch mode via 'ssub'.

Thanks.
