I am trying to set my PIC16F913 to use a internal ossilator in code without changing any other files. acording to another post i just add "@__config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_OFF & _CP_OFF" to the code but i get a error on compiling "Overwriting previous address contents" can any one shed some light on this

Code:
INCLUDE "MODEDEFS.BAS"

Asm
	__config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_OFF & _CP_OFF
    ERRORLEVEL -306
