        In the save area ... registers 14 thru 12 are placed at offset 12,
which means R14 goes to +12, R15 goes to +16, R0 goes to +20, R1 goes to +24,
and so on.  Offset 4 points to the next SAVE area, right?  And offset 8 to
the previous SAVE area, right?

        So what does offset zero refer to?  If you say "R13 goes there",
I won't shoot you.  Pointing to itself would provide validity checking,
but is that what offset zero does?  If not,  then what?
