[Jon A. Lambert:]

 &gt;It also claims the operand stack is FIFO.  I thought this was odd.

Definitely. If its FIFO it isn't a stack. By definition.

 &gt;Each method gets it's own stack frame.  Perhaps this is peculiar
 &gt;to Microsoft's or Symantec's VM.  The book is not really clear on
 &gt;whose implementation is being referenced.   And I don't know if 
 &gt;it's authoritative, it may well be misleading.

Could well be. The bit about the stack frame is correct, but when I
looked just now, I saw no mention of a frame pointer to point at it.
In the instruction format, locals are addressed via an offset within
the frame, so most implementations will likely use a frame pointer.

"Optop" sounds like the stack pointer, which they do define. Not
clear what "Vars" refers to. All non-local variables are inside classes.
I'd guess its the constant table.
