SubString (NoOfChars)

Example

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

Where,

str: ABCDEFGHI

startAt = 2

noOfChars = 4

Right-click on the function transformation object and select Preview Output. You can see that Astera Data Stack has returned a part of the string, starting at position startAt, and of length, noOfChars.
