First, thanks, Dr. Nemeth, for a fine summary of the similarities/
differences between NFBCALC and UCALC.

I believe that since one is using a computer rather than a handheld
calculator, one should take advantage of useful features (such
as destructive or nondestructive backspacing) available on the
computer. In addition, a person used to using the arrow keys,
backspace and/or rubout/delete to correct errors wouldn't be
thrown for a loop when s/he finds such features unavailable
in a calculator, in this case, NFBCALC.

Just one opinion.
