Thanks, Steven, I was afraid of this. The problem is that I need TEE so
I can see the XCOPY status while it's running (I need to see what files
XCOPY is "currently copying"). If XCOPY was open source GPL, I could
add a command line /TEE:filename (-TEE:filename) option so a pipe
wouldn't be necessary.

It's in there, I look at it from time to time. Search on "&" and click
on the two hits titled "Command Operators and Redirecting ...". Don't
try searching on "Command Operators and Redirecting", though -- for some
stupid reason that won't work.

If there was a way to disassemble the .inf files they could be converted
to HTML documents or plain text for "a better viewing experience". I've
never created .inf files but I'm told they're HTML/SGML based. My own
articles are all SGML tagged and I then run them through some of my own
code to create HTML.

Thanks again,

- Peter
