k Strings
A string is a series of characters enclosed in double quotes. In a program, strings are used
to specify display text. A string made up of numbers (like "123") or an expression (like "
x –1")
cannot be processed as a calculation.
To display a string at a specific location on the screen, use the Locate command (page 8-23).
• To include double quotes (") or a backslash (\) in a string, put a backslash (\) in front of the
double quotes (") or backslash (\).
Example 1: To include Japan: “Tokyo” in a string
"Japan:\"Tokyo\""
Example 2: To include main\abc in a string
"main\\abc"
You can input a backslash from the menu that appears when you press
6(CHAR)
2(SYMBOL) in the Program mode, or from the String category of the catalog that appears
when you press
!e(CATALOG).
• You can assign strings to string memory (Str 1 through Str 20). For details about strings, see
“String Memory” (page 2-8).
• You can use the “+” command (page 8-27) to connect strings inside of an argument.
• A function or command within a string function (Exp(, StrCmp(, etc.) is treated as a single
character. For example, the “sin” function is treated as a single character.
