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.
