Instead of just showing you a picture, as I do, below, I should be able to just give you a URL so you can run it yourself, but I can't because I don't actually have a place to post the files for you to address (without seeing advertisements or in other ways compromising or inconveniencing my friends). The only web server I have access to is my own and it has only temporary IP addresses which Facebook will not even let me post. Besides, why bother to post a temporary IP address? I think it is funny how money controls everything, without money, our society says, don't even try to do anything.
Julian also suggests that Mickey Mantle, who was in charge of customer support of E&S, may know more.
The time when this would have been written by the way is about 1977.
If anyone knows how to reach Mickey Mantle, please let me know.

The problem is, this is a problem whose general case is actually fairly difficult. Why not make everyone re-solve this themselves? Its good for them, it makes them think about fundamental principles. I have no idea what these people were thinking.
