Function
Write DataItem into Location in EEPROM.
• Location is a variable/constant/expression (0 – 255 on BS1, 0 – 2047
on all other BASIC Stamps) that specifies the EEPROM address to
write to.
• DataItem is a variable/constant/expression specifying the value to
be stored.

Explanation
The EEPROM is used for both program storage (which builds downward
from address 255 on BS1, 2047 on all other BASIC Stamps) and data
storage (which builds upward from address 0). The WRITE instruction
stores a byte of data to any EEPROM address. Any location within the
EEPROM can be written to (including your PBASIC program's locations)
at run-time. This feature is mainly used to store long-term data from
EEPROM; data stored in EEPROM is not lost when the power is removed.
The following WRITE command stores the value 245 at location 100:
