Select "Array" as the Variable Type.
Provide a name for the Array Variable.
Define the elements of the array, specifying their type and values.
Click the "Save" button to create the Array Variable.
What are some common use cases for Array Variables?
Answer: Common use cases for Array Variables include:
Storing lists of items such as employee names, product IDs, or customer addresses.
Managing collections of data that need to be processed or displayed together.
Performing calculations or operations on multiple values simultaneously.
How do I add new data to an existing Array?
Answer: To add new data to an existing Array:

Use the appropriate index to access the desired element.
Enclose the Array Variable name and index within ## symbols.
For example, ##User_List[2]## will retrieve the third element from the 'User_List' array.
What happens if I try to access an index that is out of range in an Array?
Answer: If you try to access an index that is out of range in an Array, it may result in an error or return a default value depending on the system's behavior. It is important to ensure that the index falls within the valid range of the Array to avoid unexpected results.
Can I perform mathematical operations on Array elements?
Answer: Yes, you can perform mathematical operations on Array elements:
For numeric Array elements, you can add, subtract, multiply, divide, or perform other mathematical operations.
Ensure that the operations are valid for the data type of the Array elements to avoid errors.
