Thanks, kyak, that worked like a charm. Now one can recall previous
lines and make corrections or changes as needed.
As an aside, in all my searching of the directory structure, I found
another "calculator", dc, that is built but not packaged. It is a
reverse polish calculator that depends on bc. I just copied the
executable over to my Nanonote and it executes fine. Found its man
page on the web. Yet another interesting tool on the Nanonote:) I
have used HP Reverse Polish Calculators for many years and find that
notation natural by now.
Thanks again for making this change available. I hope there is a way
to integrate it into the builds for the Nanonote. Not being able to
recall and correct is just not acceptable, especially with the small
keyboard that must exist on a device as small as the Nanonote.
Reducing keystrokes is always a "good idea"!
