Well, I tried this as follows:
I opened up COMMAND.COM with NU. Searched and found the string COPY.
Changed COPY to KOPY and saved the changes. Rebooted my AT.
Issued the command COPY A:foo B: and to my surprise it understood the
COPY command just fine and copied foo over to B:. It also failed to
understand KOPY and thought it to be a Bad command.
Do I have to do something else to rename COPY to KOPY. After this all I
really have to do is to write a batch file COPY.BAT that will invoke
KOPY except when the source drive is C:.
Any suggestions, anyone ?
