Figure 7-8 shows a window called Memory Map. You can view this window by clicking
Run and selecting Memory Map. The Memory Map uses different colors to show how
both the BASIC Stamp module’s RAM (variables) and EEPROM (program memory) are
being used. The EEPROM Map has two graphs. The bar at the far left shows that only a
small fraction of the program memory is used to store the photoresistor program from
Activity #2. By scrolling to the bottom of the EEPROM Map’s main window and
counting the bytes highlighted in blue, you will find that only 101 bytes out of the 2048
byte EEPROM are used for the program. The remaining 1947 bytes are free to store data.
