Solution 12037: Performing String Operations on the TI-83 Family, TI-84 Plus Family, Or TI-Nspire™ Handheld In TI-84 Plus Mode.
How do I perform string operations on a TI-83 family, TI-84 Plus family, or TI-Nspire handheld in TI-84 Plus mode?
The main function of strings is to display text. In programming, strings allow programs to display information or prompt the user to perform some action. Following are some of the operations that can be performed with strings:
Concatenation means putting strings one after another and making them one string. For example, if string1 is "abc" and string2 is "def", then string1+string2 is a new string "abcdef".
To concatenate two or more strings, follow the steps below:
• Enter string1, which can be a string or string name.
• Press the [+] key.
• Enter string2, which can be a string or string name. If necessary, press the [+] key and enter string3, and so on.
• Press [ENTER].
2. Converting an equation to a string.
The Equ>String( command, located in the CATALOG menu, converts the content of a Y= variable to a string and stores it as a string variable.
3. Converting a string into an equation.
The String>Equ( command, located in the CATALOG menu, convert a string into a variable and stores it in the Y= variable.
4. Converting a string into an expression.
The expr( command converts a string to an expression and executes it.
