What a pain. I don't remember anything that messy when adding 18F1320 support to my programmer. If you're desparate, you can rummange thru my source code to see what it does. Go to http://www.embedinc.com/easyprog/sw.htm and download the development software. I've programmed a bunch of 18F1320 with this software without any problems. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The PICList is archived three different ways.
