How to store in EEPROM of PIC16F886

[AD76XYZ]

Till date I have implemented the things. Reading keypad, storing into array and then comparing the two array. Now I want to store this array data, that is password in EEPROM of PIC16F886, since this controller has 256 byte of EEPROM built in. I read CCS C help files and other code. I have some questions, please suggest.

What is the use of #ROM?
I did not understand this, please give some example.

To write into internal EEPROM.
write_eeprom(address, value)

To read from internal EEPROM.
read_eeprom(address)

After reading keypad I am getting ASCII value of keys, say after pressing 1 I will get ASCII value of 1. So how I will write to eeprom.
Like this.
write_eeprom(0, digit[i]), will use loop. Any change is required in format of number to store in eeprom.
Like wise reading from eeprom.

Another thing, when eeprom writing is going on we have to wait in code, right? We have to wait to finish writing of eeprom, so how to implement this. Can please anybody give code or example.

Most of what you want is in the CCS manual and the CCS examples folder.
