Write to memory? (PIC internal EEPROM)

Question

I am following this tutorial which shows you how to write to data to Internal EEPROM. The only thing that is different in this tut is that they are using p18f4520 and I am using PIC18F87J11. When I try to build the code I get the following errors, may I know why?

113:Error [1105] symbol 'EEADR' has not been defined
113:Error [1101] lvalue required
114:Error [1105] symbol 'EEDATA' has not been defined
114:Error [1101] lvalue required
116:Error [1205] unknown member 'EEPGD' in '__tag_222'
116:Error [1131] type mismatch in assignment
117:Error [1205] unknown member 'CFGS' in '__tag_222'

Answer 1

Sorry, but there is no internal EEPROM in PIC18F87J11 MCPU! Your example is intended for MCPUs with internal EEPROM.
