[EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads Hi Jinx, Ooops, it was because of actual chip limitations. I tried with 18F8720 selected and MPLAB accepts more bits because of the 128K ROM size. I got a request to implement a "program DEBUG vector" option in the DIY programmers and was trying to work out what to expect with GOTO addressing. many thanks. regards Tony -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
