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.
