lookup2?

[jonas2]

Hello

I am beginning to understand this instruction, but I thought it was for
make the conversion.

There are 40 bytes of digital data (0123456789) has just saved to the eeprom data and each is compared
in the table and Lookup2 not return anything and therefor datat left unchanged.
and so on for 40 bytes.
And if he finds it changes datat to be written to eeprom.
And if I want that every 40 bytes of a change is saved
This way:
1st byte is a 1 is written in eeprom, R
2nd is a 2 bytes will be written in eeprom in S

40th is a 8 bytes will be written in eeprom in Z

How can I do to create my table

Thank you
