A quick note about ARCHIVE on the 48sx: it doesn't back up all of user
memory, like it says it does.  They forgot to back up the user and system
flags.  I was really ecstatic about archiving, wiping out memory, and
restoring everything from my PC, until I noticed the clock was missing.
I then had to go back through the list of system flags and remember what
I had set while reading through the tomes that come with the calculator.
(Like -2 for numeric pi, error beeps off, etc.)

I wrote a backup that saves the flags in a variable before the ARCHIVE.
I also have a small program that copies that variable into the flags,
that I have to remember to run after a RESTORE.

It is really neat to be able to nonchalantly clear the memory.  Especially
after having numerous, very annoying Memory Lost episodes with my 28S.
