Compare the output in the Debug Terminal to your predictions, and reconcile
any differences.
EEPROM stands for Electrically Erasable Reprogrammable Read Only Memory.
EEPROM memory is nonvolatile.
disconnect power, then reconnect power, and the values you stored will still be there.
Compile-time vs. Run-time - DATA directives are processed when the BASIC Stamp Editor
compiles the program. In other words, DATA directives are processed at compile-time. The
WRITE command can change the values in EEPROM while the program is running. That's
