Gerson.

A missing comma, actually. Seems I mixed up some code relating to regions using a comma as decimal point.

The commas do show up in the printer output, however:

High accuracy is another great feature, not to mention the printer and the card reader, BTW.

I assume the radix is selected automatically according to the user's region. That's a nice feature, as long as the user is allowed to change it occasionally, perhaps by means of an expanded decimal point selection box ( | . | , |Auto| ). Anyway, the choice between period and comma was not offered by the original HP-67, as far as I know.

I know the HP-67 had not constant memory and FIX 2 was the initial display mode, but it's annoying to manually changing to FIX 9 (ok, just two keystrokes, DSP 9, but annoying just the same). Would it be possible to save the display mode? By the way, that's a feature I dislike very much on the HP-45 (that's why I like my HP-35 better). FIX 2 is fine only on financial calculators. The default FIX 4 on later calculators is only slightly better, but that was not a problem on my first HP calculator, the HP-15C, as the continuous memory preserves the display mode. I guess this was originally intended to save battery life in the LED calculators, but somehow this ended up going to the LCD calculators as well.

Thanks for yet another great simulator!
