Can anyone give me information on the EDIT PB instruction?  I'm assuming it
existed on the Series II and I know that it's octal 20470 and that you
push onto the stack the address of a "program", a destination pointer, a
data pointer (all word addresses, I believe) and a 0 and then
  ASSEMBLE(CON %20470)

Any guidance would be greatly appreciated.  Neither the SPL manual nor the
software pocket guide (which claims to list the series II instruction set)
admit to such a thing existing.  I'm needing to modify the "program".

Thanks,
Ted
