Is 32SII programming FOCAL?
My DM41X is on the way and I am looking forward to playing with it. I have enjoyed 35s, 42s, 32sii. The programming seem very similar for casual use. So is 32sii full FOCAL, subset of FOCAL, or not FOCAL at all?

No, rather RPN Keystroke like HP67. An important element that is missing would be e.g. alphanumeric labels. A major innovation of the 41 programming (FOCAL) was that your own programs could then be used like internal commands. e.g. the 41 has no hyperbolic functions but if you write a program "LBL SINH" you could use this like internal functions even in other programs. You can see 32sii programming as subset but in the end, focal is a little more than only more functions.

Peet,
Thank you for the good example that I immediately relate. I was using the EQN editor on 35s last week to calculate a sinc(x), where 'x' is a rather long expression of 4 parameters. I realized that without a sinc function, I had to repeat typing for numerator and denominator.
Also I feel that the lack of alpha variable name i 41 is a disadvantage?
