Example

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

Where,

str = aAbBcC

index = 0

Right-click on the function transformation object and select Preview Output. You can see that Astera Data Stack has returned “True”, as the character in the specified numerical position is a lowercase alphabet.

Conversely, if we replace the index value with “1”, the output value will return the Boolean value, “False”, as shown below:
