Request for suggestions: algebraic equations in Free42

[Thomas Okken]

The next version will have an unlimited stack. (As an option, the default will still be the four-level stack! That will always be necessary because lots of legacy programs won't work with the unlimited stack.)

The idea is to combine the ease of RPN keystroke programming with the power of RPL, or at least a few key parts of it.

Whether this will run on the DM42 remains to be seen, I think RAM is a bit tight even now, so it might not be practical.
