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.
