I had always wondered if the designers of the solver had put in a hidden command to write to a sum list. You can read from a sum list via the ITEM command, but you can't write to a sum list from an equation. If you could, it would open up the solver to all kinds of additional applications.

I wrote to Mr. McClellan and he responded. I don't think he would mind if I showed his response here, because I think many of us would find this very interesting.

These guys were brilliant to have built a solver with so many advanced capabilities. My hat is off to them.

Thanks for sharing that interesting information, Don.
