Hi, I want to move the data of the rom to the eeprom of a pic18f452, what is my mistake?

Code:
#include <18F452.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP,NOBROWNOUT
#use delay(clock=20000000)

int i;

#define ROMDATA   0x7FA0
#ROM int8 ROMDATA={"123044"}

void main(){

for (i = 0 ; i<6 ; i++){
   write_eeprom(i,ROMDATA[i]);
}

while (true);
}

This should do it:
Code:
#include <18F452.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP,NOBROWNOUT
#use delay(clock=20000000)

#define ROMDATA   0x7FA0
#ROM int8 ROMDATA={"123044"}

void main()
{
   int8 i;
   int8 data;

   for (i = 0 ; i<6 ; i++)
   {
      data = read_program_eeprom(ROMDATA + i);
      write_eeprom(i, data);
   }

   while (true);
}
