I 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 8-17).
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 (CHAR)(SYBL)
in the PRGM mode, or from the String category of the catalog that appears when you press
C(CATALOG).
You can assign strings to string memory (Str 1 through Str 20). For details about strings, see
“String Memory” (page 2-7).
You can use the “+” command (page 8-20) 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.
