This doesn't matter too much unless you're worried about speed, but has 
anyone noticed that most of the rom calls for the TI-83 just refer to other 
addresses in the ROM, for example, the _clrlcdfull call is something like 
this:

_clrlcdfull:
  call $0031
  ret

If someone were to document all the PROPER addresses, this would speed each 
rom call by around 11 clock cycles I think..
It's not extremely important, but as I said, it would speed up execution.
