No instead at line 5 you should have 5 movwf fsr ;copy to the variable named in cblock ^^^^ to explicitly load the FSR and then to access the required register you need 8 movwf 0x00 ;and to the address in fsr as you have written, but to show your intent, you should use the mnemonic INDF instead of 0x00. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
