Define variable as byteQuote:

Read first eeprom and put result to your variable
write that variable to second eeprom in same address
go to loop for full range of 256 location (24C02).
For 24C02 is from address 0 to address 255.
if loop come to end of count all is finished.
Use I2C command to read and write EEPROM and make different I2C address
for 1st and second EEPROM by hardware pin setup.

what u have schematic please share here brotherQuote:

Good luck getting someone to do your school work for you.
i have schematic Pic16F84A for eeprom 24Cxx copier now (in attachment)but i dizzy source code for schematic here.u can help me make source code.thanksQuote:

Did one eleven yrs back :)
Might have been my first PBP program.

This hex expects normaly closed switches for Copy and Verify.
The LEDs need their polaritys reversed and are to be tied to +5volts
instead of ground for this hex also.
