end of the list (&, /, +, –, etc.).
The Catalog Help App includes details about each command.
Options not currently valid are grayed out. For example, the Flash Apps
(
…) menu option is grayed out if no Flash applications are installed on
your TI-89 Titanium; the User-Defined (

you have not created a function or program.

with the same letter.
