**Example**

In this example, we are passing the required parameters to the function transformation object using a *Variables* object.

Where,

*CharsTolookFor* = # @ab

*lookIn* = 1234 @# ABC

Right-click on the function transformation object and select *Preview Output.* You can see that Astera Data Stack has returned True, indicating that the the *CharsTolookFor* string is present within the *lookIn* string.
