Solution 12024: Creating Strings on the TI-83 Family, TI-84 Plus Family, or TI-Nspire™ Handheld in TI-84 Plus Mode of Calculators.

How can I create a string variable on the TI-83 family, TI-84 Plus family or TI-Nspire Handheld in TI-84 Plus Mode of calculators?

A string is a sequence of characters enclosed within quotation marks. Characters are the units combined to form a string. Each number, letter, and space is one character. Each instruction or function, such as sin( or tan( is one character. Quotation marks do not count as string characters.

To enter a string on a blank line on the Home screen or in a program:

1) Press [ALPHA]["] to indicate the beginning of the string.
2) Enter the string text (this may include number, letters, functions, instructions, or spaces).
3) Press [ALPHA]["].
4) Press [ENTER].

Please Note: Calculators of the TI-83 and TI-84 Plus families have 10 built-in variables to which strings can be stored. Other variables cannot be used to store strings.

To store a string to a string variable:

1) Press [ALPHA]["] to indicate the beginning of the string.
2) Enter the string text.
3) Press [ALPHA]["] to indicate the end of the string.
4) Press the [STO->] key.
5) Press [VARS] to display the VARS menu.
6) Move the cursor to 7:String.
7) Press the [ENTER] to display the STRING secondary menu.
8) Select the string variable from str1 to str0 to which to store the string.
9) Press [ENTER].

Please Note: To display the contents of a string variable on the home screen, select the string variable from the VARS STRING menu, and then press [ENTER].
