OK. Where is the second reference to register 2? Remember, the sole purpose of the example was to produce the register XREF report, not to execute, which it won't. I first noticed the bug in a 600 line program that produced a full page in the register XREF report. The example was minimal so the issue would obviously stand out.
I use S-cons quite a lot in my work, but not very often something like S(0(6)). Actually, it was SL2(0(6)), but there was no point in littering up the example with extraneous junk.
