Ok, I know this is going to sound like a strange request so I want to
make some disclaimers first. I am not a virus writer. I don't want
to kill machines. I'm not trying to write a virus. I made a bet with
a friend that the copy command (or any other internal dos command)
could be "turned off." What I want to do is simple. I want dos to access
a file called "copy.bat" whenever anyone types in a copy command. The
problem is that dos always checks for internal commands (copy) first,
so dos never even looks at copy.bat, it just declares invalid number of
parameters. I'm sure this can be avoided, but how? Again, I know it sounds
suspicious. I declare again that I'm not writing any virus programs. My
full name is below. As proof of my good intentions (or non-malicious any-
way) if you see any new virus programs out that use copy "turn-off" you
can blame me and send the police after me. 
By the way, the bet with my friend came after an argument of how to
turn off external commands (rename them, hide then, and replace with a
file of the same name). Reply by e-mail if that's ok. Thanks in advance.
