Hi: I am using a 16F84 to read serial data and want to store it in sequential files (using FSR). Rather than hard code the starting file address I would like a way to make it the next available address after the last CBLOCK/ENDC assignment. If this is not possible, can I assign the data storage starting at file 00 and somehow tell the assembler where to start the first CBLOCK? PS. has anyone got AN555 to work on a 1684? Thanks, Brooke
