Thank you, that is most useful.
Note that code written by contractors may be exempt. I say "may be"
because it depends on the terms between the government agency and the
contractor. For example I wrote that memory test code as a contractor
on a work for hire basis, so it belongs entirely to NASA and would have
been eligible for release.

Given that source in Fortran and C is readily available, etc., I'd say
that your suspicion is very likely true.

This is true. As I understand things, you can copyright code, but not
algorithms. So I can write a program to calculate the date of Easter
and copyright that. But the algorithm was developed by the Roman
Catholic Church in the 4th or 5th century, and later adjusted for the
Julian calendar. So I couldn't copyright the algorithm.
(Where is the dividing line between code and algorithm? I'm glad you
asked that question. Let me know when you find an answer.)

And one person might write a more efficient version than another. Or
other variations. And that can be protected.
