You're right, D6 seems to contain some version of the HIM code. This
is a surprise to me, I had thought all this time that it didn't appear in MTS until

later.

The ultimate reference for questions like this is the driver file
which is guaranteed to be correct since it was used to write the tapes
and disk pack. It contains entries for the HIM code. I don't know
how well it works in that version, but there is at least some chance
that D6 will support TCP connections in Hercules when the HIM code is

finished.

The copyright question is complicated. It's also not the only
question that is relevant, either. There may be other legal
restrictions that apply to these programs. Do you have any reference
for the idea that IBM let these go into the public domain?

Not a chance. The only mainframe code IBM has "released to the public" was
APL but its not public domain, it’s a very restrictive licence.
Modified versions are not allowed so people jump through hoops to provide
code to patch it.

I should have said there is a common misconception that VM/370 and pre MVS/SP operating systems are Public Domain because their copyrights have expired.
This isn't true, these products never were copyright, they always were public domain.
If the copyright on the first Mickey Mouse film has just expired IBM software is going to remain copyright until long after I am pushing up daisies.

Dave is correct.? And I apologize in advance if none of this is helpful or of interest. If this is TMI for you, stop reading here without missing out on anything.? (I know, why send the email?? I just felt compelled to do so.)

Here is some information I have become aware over time. Copyright is not universal! Different jurisdictions have different rules. For example, software copyright did not exist in the U.S. until 1980.

See amendments enacted on 12 December, 1980:




Other jurisdictions, for example, Great Britain (I believe), software was always able to be copyrighted. IBM marked their programs as copyrighted regardless of jurisdiction to protect it where software copyright was legitimate. So, no matter what software said prior to 1980 IN THE US, the software was not covered by copyright. In effect, this acts like "public domain", but I am not really sure if they are the same. My limitations as "not a lawyer".

Additionally, the magic duration for the copyright seems to be 70 years. There are some mention of even longer time frames. So, the earliest copyright in the US, 1980, plus 70 years, puts us at 2050.

The picture gets more complicated when considering the IBM consent decree of 1956:



This was, of course, as US constraint on IBM from use of monopolistic practices. Welcome the world of Plug Compatible's. It is my understanding that this was the motivation for IBM's creation of two classes of software products: System Products (like OS's) and Program Products (other software). And, note, within the U.S until 1980, none of them were protected by copyright.

(This is not to say that a given organization's contract with IBM would not impose protections to those products without US copyright protection used by the customer. An entirely separate topic.)

TODAY, IBM is no longer under the consent decree:



It ended 2 July, 2001, just in time for the z systems and the gradual disappearance of documentation ever since.

Considering we are talking about copyright for products that reside in a system with TCPIP support, MTS, the Internet Engineering Task Force started operation in 1986:



TCP/IP essentially was created by these standards.

Those other, Program Products, are in all likelihood under copyright protections.
