String
About
A string is a data type that represents a sequence of characters. It can be used to store text, symbols, and even numbers in a format that can be easily manipulated. In HMI programming, strings are often used to store data such as user input, machine status, and error messages.
String variables can be manipulated and concatenated with other strings to form more complex data structures. For example, we can concatenate two strings using the "+" operator as follows:
String greeting = "Hello, " + username;
