  I *know* what I'm talking about, with regard to
access to IBM sources. I
 was at SHARE in San Francisco when the great OCO debate heated up again,
 and still have my button reading "When source is outlawed, only outlaws
 will have source" in my collection.  I remember the discussions of the
 changes in US copyright law, including court cases, which allowed program
 sources to be copyrighted and have the copyrights stand up, in
 _ComputerWorld_ and _Datamation_ and other trade rags.  

So, since you were, what was the last release that was not copyrighted and
what was the first release that was?

And when was the change to OCO?

Thank you.
