Non Volatile Memory

I'm a little new to the stamp world so this may be a silly question,
however; Is there a way to save variables in non-volatile memory so
that my program will resume after a power failure?

    you could probably just save the state info to eeprom.

    Yes, there is. Look into the WRITE and READ commands

    Your program won't be able to resume at the exact spot of a power failure,
    but you can come close. I wrote an article for Nuts & Volts (#87 -- that is
    available from our web site) that shows how to use the BS2sx multi-bank memory.

    The strategy used for saving variables can be modified to save to EEPROM.
