Now the direction instructions will appear in a more familiar format shown in Figure 4-8.
Instead of ASCII codes, they appear as the actual characters you recorded using the
directive.
This program stored a total of 10 characters in EEPROM. These ten characters were
accessed by the
as a byte, so it can access up to 256 locations, well over the 10 we needed. If the

larger, the number of available EEPROM addresses for holding data gets smaller.
You can modify the existing data string to a new set of directions. You can also add
additional
second data string will get stored immediately after the last character in the first data
string.
