Hi, I am using MPLAB C18 compiler to develop PIC18F, could you give me some suggestions how I can select different memory bank using C18? How can I use "#pragma varlocate"? Do you have some experience in memory using the C18? Thanks in advance! Luke -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
