Entering and Using StringsWhat 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.
1. Press ƒ [ã] to indicate the beginning of the string.
2. Enter the characters that comprise the string.
