   What does it do?            01/01/70 00:00      
      I activate MOVC Disable.            01/01/70 00:00      
         In that case ...            01/01/70 00:00      
            Can't tell...uses external CCASE routine            01/01/70 00:00      
               Things you can and can't do ...            01/01/70 00:00      
                  it does            01/01/70 00:00      
               (double post, please disregard)            01/01/70 00:00      
   switch can use MOVC instructions            01/01/70 00:00

                     Errr...            01/01/70 00:00      
                        There is more than just switch/case            01/01/70 00:00      
                           No C without MOVC            01/01/70 00:00      
                              Protection on other derivatives            01/01/70 00:00      
                                 Example - AT89C51            01/01/70 00:00

                                       nope            01/01/70 00:00      
            LPC Protection            01/01/70 00:00      
               naah, but make it quite a bit more difficult            01/01/70 00:00      
   Compiler Optimisation            01/01/70 00:00      
      sure, but there will still be MOVC            01/01/70 00:00      
         And upgrading the compiler can change the output            01/01/70 00:00      
            the ICEman cometh            01/01/70 00:00      
               I have found no issues with the ICE            01/01/70 00:00      
                  sure it 'works'            01/01/70 00:00      
         The Reason            01/01/70 00:00      
            no, no, no            01/01/70 00:00      
               But you said..            01/01/70 00:00      
                  if you heard what I thought I said            01/01/70 00:00      
                     Confused            01/01/70 00:00      
                        jmp @dptr is not movc            01/01/70 00:00      
                           jmp @dptr is a computed goto not a jump table            01/01/70 00:00      
   what requires a movc???            01/01/70 00:00      
      Jump TABLE            01/01/70 00:00
