[sci.crypt] copyright of derivative works

  Could someone tell me the correct copyright notice to use
for a derivative work?  That is, if I have a program already
with a copyright notice of, say, 1984 and I make modifications
to it, do I use "Copyright 1984,1986" or "Copyright 1986"?

thanks,
Bob Devine

  Sorry about the misdirected posting.  I didn't realize that I gave
the wrong group until it was already out of /usr/spool/uucp.  An attempt
to cancel the article revealed a bug that caused a core dump...
