EEPROM Initialization with MPLab

[jumper2high]

Hello all,
I'm trying to find an answer to one very simple and silly question, but failing miserably.

In MPLab, when doing an ASM source file, I was able to tell the software that I want certain values burned into EEPROM upon programming, so I did:

	ORG 0x2100
	DW b'00000000'
	DW b'01000010'
	DW b'01111111'
	DW b'01000000'
	DW b'00000000'

And it would put those five values in the first five places in EEPROM.

However, if I try this in a C-file (using MCC18) I get an error. I've tried searching for the correct way to do this for some time now, but I can't seem to find it. Because of the type and amount of data I want to put in there - I want to avoid having to convert it all to hex manually and enter it through the EEPROM Editor.

try this

void write_eeprom(unsigned char x,unsigned char y)
{
EEADR=x;
EEDATA=y;
EECON1bits.EEPGD=0;
EECON1bits.CFGS=0;
EECON1bits.WREN=1;
INTCON=0x00;
EECON2=0x55;
EECON2=0xaa;
EECON1bits.WR=1;
while(EECON1bits.WR==1);
while(!PIR2bits.EEIF);
INTCON=0xc0;
EECON1bits.WREN=0;
PIR2=0x00;
}
char read_eeprom(unsigned char x)
{
delay(100);
EEADR=x;
delay(100);
EECON1bits.EEPGD=0;
delay(100);
EECON1bits.CFGS=0;
delay(100);
EECON1bits.RD=1;
delay(100);
return( EEDATA);
}

Thanks for trying to help, but that's not what I was looking for really.
I know how to make a program that will put stuff in EEPROM, I want the PROGRAMMER (PICKit3 in my case) to put stuff in EEPROM...

Eventually, I figured it out, though:

#pragma romdata eedata_cg=0xf00000
rom unsigned char eedata_values[50] = {
				//number0
					0b00111110,
					0b01010001,
					0b01001001,
					0b01000101,
					0b00111110,
					.....and so on....
