I'd like to use the VBATV command from BatStatus in my STARTOFF
program to prevent shut off when the USB is connected. Since VBATV
returns 0.0 when connected to the USB, I could use:

<< IF VBATV THEN OFF END >>

Unfortunately, if the USB is connected when the calculator is turned
on, BatStatus continues to indicate that it is being powered by USB
even after disconnecting the USB. Likewise, if you connect the USB
after turning on the calculator, BatStatus shows that it is not being
powered by the USB. This means that with the above STARTOFF program,
if I'm running on USB power then unplug the USB without manually
turning it off, the calculator will never auto-shutoff.

Is there a simple way around this? (I mean besides "manually turning
it off" :)
