Mid (String Chars)
Example
In this example, we are passing the required parameters to the function transformation object using a Variables object.
Where,
str = ABCDEFG
startAt = 3
noOfChars = 2
Right-click on the function transformation object and select Preview Output. You can see that Astera Data Stack has returned a string beginning from the specified startAt position, and of specified noOfChars length.
