Thats a really bad habit to get into.  Unless something is a romcall, you
can't be guaranteed that TI will put that same code in the same location.
On a different rom, there might be a different instruction.  You can look at
all roms made up to this date and say its compatible up to a certain rom
version, but you can't guarantee that it won't change on a future rom
version.  In this case we're talking about a single byte, thats ridiculous
that you'd take such a risk over one byte.
