String Variable Control
Various actions are available to target HMI string variables.
String Assignment
Inserts a string into a string variable. When the action below is executed, $str1 stores the string “Compiling Technology”.
String Insertion
You can insert the desired string in a specific location in a string.
If the contents of $str1 was “uvwxy” then it would become “uvabcwxy” after the above action was taken.
String Deletion
You can delete all or part of the contents of a string variable.
String Conversion
If a string variable is in numeric form (for example, “123”), it can be replaced with a number and stored in the HMI variable. The opposite is also possible.
Parse String
You can divide the value of a string variable into multiple variables by delimiters. For example, if a string variable named $person_info contains the value “John,USA,36”, it can be stored divided and stored into $name, $country, and $age, respectively.
The user can decide what the delimiter should be (for example, / or , etc.). If the delimiter can change at runtime, then you can specify the separator by the string variable name.
To convert to numeric values, use numeric variables, not text variables.
