SUMMARY
This chapter introduced a variety of EEPROM and program management techniques.
EEPROM management focused on declaring and naming
EEPROM bytes and groups of bytes used in the program. Techniques for counting resets
were introduced for both toggling between different SumoBot program modes and for
selecting from a list of program modes. Programming focused on adhering to code
conventions for the sake of making large programs easy to build from smaller programs
in your library.

keyword can be used to give a meaningful name to the starting address of each group of
bytes. Since this Symbol name represents an address in EEPROM it simplifies

DataItems
A procedure was introduced for merging components of smaller programs into larger
programs. It depended on keeping programs organized in common sections: Title,
Compiler Directives, I/O Definitions, Constants, Variables, EEPROM Data,
Initialization, Main Routine, and Subroutines. It also depended on using a common
naming convention for temporary and counting variables.
