TI-83 Plus Communication Link 647
Note:
You can transfer all real variables, pics, and programs from a TI-82 to a
TI-83 Plus
if
they fit in the RAM of the TI-83 Plus. The RAM of the TI-83 Plus is
slightly less than the RAM of the TI-82.
Receiving from a TI-82 — Unresolved Differences
The software built into the TI-83 Plus cannot resolve some differences
between the TI-82 and TI-83 Plus. These differences are described
below.
You must edit the transmitted data on the receiving TI-83 Plus to account
for these differences. If you do not edit these differences, the TI-83 Plus
will misinterpret the data.
•
The TI-83 Plus reinterprets TI-82 prefix functions to include open
parentheses, which may add extraneous parentheses to transmitted
expressions.
For example, if you transmit
sin X+5
from a TI-82 to a TI-83 Plus, the
TI-83 Plus reinterprets it as
sin(X+5
. Without a closing parenthesis
after
X
, the TI-83 Plus interprets this as
sin(X+5)
, not the sum of
5
and
sin(X)
.
•
If a TI-82 transmits an instruction that the TI-83 Plus cannot translate,
the
ERR:INVALID
menu displays when the TI-83 Plus attempts to
execute the instruction.
