Folders and Variables
Folders give you a convenient way to manage variables by organizing them into related
groups.
The TI-89 Titanium has one built-in folder named
MAIN. Unless you create other folders
and designate a user-created folder as the current folder, all variables are stored in the
MAIN folder by default. A system variable or a variable with a reserved name can be
stored in the
MAIN folder only.
