Things are a little different for ROM based programs. We call it XROM in the WP 34S. Since ROM based code doesn't change, we can precompute all jump targets. Furthermore, SKIP and BACK in XROM use absolute distances, not step counts. Of course no one ever performs these calculations manually. It's the assembler as part of the build process that does all the tedious counting for us.
