index = 1
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 alphabetical.
Conversely, if we replace the index value with “0”, the output value will return the boolean value, “False”, as shown below:
