Entering and Using Strings
What Is a String?
A string is a sequence of characters that you enclose within quotation
marks. On the
TI-83 Plus , a string has two primary applications.
•
It defines text to be displayed in a program.
•
It accepts input from the keyboard in a program.
Characters are the units that you combine to form a string.
•
Count each number, letter, and space as one character.
•
Count each instruction or function name, such as sin( or cos( , as one
character; the TI-83 Plus interprets each instruction or function name
as one character.
Entering a String
To enter a string on a blank line on the home screen or in a program,
follow these steps.

ã
] to indicate the beginning of the string.
