That stuff gets written to stderr for no particularly good reason, so
redirecting stdout won't help. I don't think MS-DOS gives you a way
to redirect stderr.
(You know there's a 'Copy' on the DOS console window's menu, right?

I think you might have to create a shortcut and set the shortcut
properties, but I'm not sure Win98 supports it at all.

In Pythonwin or Idle, you might have a scrollbar on your evaluation
window. (I don't know what ppm is, and I don't use Pythonwin or
Idle.) In that case, maybe you could just run the execfile line.

That makes a lot more sense. It's there to make it easier to run
PySol under the GNU debugger.

Yes, and with good reason. :)

PySol, obviously. I just type 'sudo apt-get install pysol', and I
have... a pysol command that tells me 'bad .pyc magic number'. So I
delete /usr/share/pysol/pysol.pyc, which is the file strace pysol
tells me python is accessing right before it dies, and... 'can't open
/usr/share/pysol/pysol.pyc'. Well, sure. And there's no apparent way
to create it.
So I sudo apt-get remove pysol, apt-get source pysol, discover apt-get
source is missing 'dpkg-source', figure out that dpkg-source is in the
'dpkg-dev' package, sudo apt-get install dpkg-dev, then apt-get source
Now Python still complains about a bad magic number in pysol.pyc, but
I also have a src directory, and when I cd src and python pysol.py,
(Turns out pysol ships with a .pyc file built for Python 1.5.2, and I
have Python 2.1.1 installed.)
