Program counter, Optop, Frame and Vars are the ones listed in
the book I've been reading, QUE books "Using Java 1.1".
It also claims the operand stack is FIFO. I thought this was odd.
Each method gets it's own stack frame. Perhaps this is peculiar
to Microsoft's or Symantec's VM. The book is not really clear on
whose implementation is being referenced. And I don't know if
it's authoritative, it may well be misleading.
