Edit *all* the P16C6x.INC files in the MPLAB directory, or if your lazy, just the P16C63.INC file, to add as the 4th line: ERRORLEVEL -224 .. and the message will miraculously dissapear. The assembler bug is *fixed* permanently (unless you replace the file someday and it comes back to bite you!). Easy enough? > Message: Using default destination of 1 (file) Add: ERRORLEVEL -305 .. to your source file. I'm not sure what this means, someone else may explain. Either way, it doesn't stop anyhing working. -- Cheers, Paul B.
