Oops, Resend to list. 1st try went direct. Sorry `bout that, David. =->> :04400E00F93F010075 =->This line just sets the fuses (at location 0x2007 which is the =->Microchip standard) and for some reason I can't understand the word at =->0x2008. You can get the fuse part by adding a __config 0x3FF9 line in =->your MPASM source and (if it is really necessary) I suppose you could =->also add: =-> =-> org 0x2008 =-> data 0100 =-> =->Of course as John mentioned you probably don't want 0x3FF9 all the =->time and the correct word depends on the desired configuration David, Cool! Much better than my solution. For my education ( and hopefully others) would you be so generous as to explain the decoding of that hex line? Thanks very much in advance! Scott
