	That is how I believe so. I think the program (or
for that matter, any program that requires a key disk)
checks the key disk for the "error unduplicable at home".
There are some other programs, I believe, put part of
the program codes permanently on the original disk. They only
load those codes if the error on the original disk is confirmed.

	It just exits to DOS with the message "no key isk".
