Solve w/ HP-41 Formula Eval Module

[Gene]

What values are in Z and T the first time this is executed?

If formula is in ALPHA and guesses in X and Y, then I don't see anything that pushes X and Y into Z/T the first time through the loop. Doesn't that mean you could have an error based on bad data in Z/T ?

Seems like it needs a DUP2 command of some sort to DUP XY into ZT ? That might prove useful for more than just this instance.

And sorry :-) What does VIEW X(3) mean/do ? VIEW X is clear, but what is the (3) in there do ?
