I am currently developing a project using a PIC18f4520. I am using the #rom directive to store some constants in the program memory my project puts characters from a PS/2 keyboard on the CRT of an analogue osciloscope. I made this project on a pic16f877 and it worked fine but I needed more RAM so I switched on 18f4520 and this warning still appears.
