Of course - that's what I had in mind. I think, the add/sub method is
fine. I will use this for the PIC-lib's in the Debian-package.

Thanks a million!  Slowly I'm getting a feeling again for assembler
programming - reminds me of the good old days, where I spent hours
programming an eprom manually, just to figure out, that there was a bug
in the assembler code :-)
