eeprom help

i'm creating a user data base for 4 users
users enter there name, age, and gender

after that i want to save it on to the internal eeprom
the pic i am using is a pic18f452 with 256 bytes

i've done some searching on the forum, and i just get confuse
key is connected to port c
lcd is connected to port b (4 bit mode)
a/d is used on port a

can someone show me an example of how i would do this, i know this seems like a stupid request, but i'm here to learn. i've also seen some examples from the sample code webpage, but i can really understand it too well.

any help would be greatly appreciated.
thanks a lot
