"con" and command line

[Mike Anderson]

Why does my system freak out when I type "edit con.cpp"

If I just type in "con" and press Enter I get the error message:

' ' is not recognized as an internal or external command,
operable program or batch file.

For some reason "con" with all variations of extensions seems to be
filtered out by Win2k. What is going on and what is the purpose of
this?

I have a feeling CLOCK$ is as well (it is in early DOS through W98)
