Generally, you can transmit items to a TI-83 from a TI-82,
but differences between the two products may affect some
transmitted data. This table shows differences for which
the software built into the TI-83 automatically adjusts
when a TI-83 receives TI-82 data.

For example, if you transmit from a TI-82 to a TI-83 a
program that contains
n
Start on a command line and then
display the program on the receiving TI-83, you will see
that
n
Min has automatically replaced
n
Start on the
command line.
The software built into the TI-83 cannot resolve some
differences between the TI-82 and TI-83, which are
described below. You must edit the data on the TI-83 after
you transmit to account for these differences, or the TI-83
will misinterpret the data.
The TI-83 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, the TI-83 reinterprets it as sin(X+5. Without a closing
parenthesis after X, the TI-83 interprets this as sin(X+5), not
the sum of 5 and sin(X).
If a TI-82 instruction that the TI-83 cannot translate is
transmitted, the ERR:INVALID menu is displayed when the
TI-83 attempts to execute the instruction. For example, on
the TI-82, the character group Un-1 is pasted to the cursor
location when you press y [UnN1]. The TI-83 cannot
directly translate Un-1 to the TI-83 syntax u(nN1), so the
ERR:INVALID menu is displayed.
Note: TI-83 implied multiplication rules differ from those of the TI.82.
For example, the TI-83 evaluates 1à2X as (1à2)äX, while the TI-82
evaluates 1à2X as 1à(2äX) (Chapter 2).
