To check whether the specified character within a string, in the specified index position, is a white space.

Example
In this example, we are passing the required parameters to the function transformation object using a Variables object.
Where,
str = 1a2 3c d
index = 3
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 white space.
Conversely, if we replace the index value with “2”, the output value will return the Boolean value, “False”, as shown below:
