In-Reply-To: <spam_OUT199604300533.WAA16735TakeThisOuTdfw-ix9.ix.netcom.com>> How do you define a sequential group of data registers i.e. reg 20 thru reg 2f as a contiguous buffer for receiving serial data over the comms link? There has to be a better way than RX_BUFA equ 0x20 RX_BUFB equ 0x21 etc etc. Bruce

To try and cut down the intermediate bit name typing I have ended up as follows cblock RX_BUF r1 r2 r3 r4 r5 r6 r7 r8 r9 endc Ends up being useful to identify bytes when using MPSIM or the emulator also!
