    Well, Perl is just something I'm using because bash isn't as
friendly in the use of floating points, and Perl has the printf funtion.
 But it could be almost anything, really- C, Informix...even "bc" the
"Big Calculator".   :>

    I'd be interested to look at Python, for example...though I don't
think it would buy me anything; there's no graphics intended on this
machine- it's a fanless Celeron 400. It's intended to be easy on the
power, and do a tiny, tiny job.

    Yeah, take another look.  I need to do a pictorial or something on
CounterMoon.org, but I'd like to have something to show, first.  Right
now it's  a 'ring' of cables that connect boards on my workbench.  :)
