Update: I just checked the 50g AUR, and the "RReg" commands (e.g. R0=A W) have been extended (in the Saturn simulator used by the 50g) to allow more fields than just W. Since other fields can be used now (e.g. R0=A X), the source code must specify the desired field. The W field cannot be assumed like it was on the HP 48.

So there's Lesson #3 to be learned here too: Check the 50g AUR (beginning on page 6-19) for the Saturn Assembly Language used in the HP 50g. It is much richer than the HP 48 Saturn Assembly Language.
