* Programs created using commands available only in the latest OS
version will not transfer to graphing calculators with an earlier OS
version.
* App Vars and Programs should be reviewed for use after the transfer
between the TI-84 Plus Family and TI-84 Plus C graphing calculators.
Some App Vars may not set up an App as expected. Some Programs will
need to be modified due to the difference in screen resolution and new
commands.
