Example

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

Where,

str = helloABCworld

start = o

end = W

isCaseSensitive = False

Right-click on the function transformation object and select Preview Output. You can see that Astera Data Stack has returned ABC, the value enveloped between the start value “o” and NOT case sensitive end value, “W”.
