**Example**

In this example, we are passing the required parameters to the function transformation object using a *Variables* object. We will be appending the string, “HELLO WORLD”, into an empty ‘Test’ .txt file.

Where,

*str* = C:\Users\Kanwal.Azim\OneDrive - Astera Software\Desktop\Functions Documentation\Test.txt

*text* = HELLO WORLD

Right-click on the function transformation object and select *Preview Output.* While the *Data Preview* will not generate an output. Upon opening the file for which the path was defined earlier, you will see that Astera Data Stack has appended the provided string value into this file.
