When a function is executed in the Translator an annotation window will appear to the right of it. The annotations show you the real time results of your code.
Annotations are key to faster and more comprehensive development in the Translator.
This picture shows a number of functions with annotation windows:
Verify or view your logic in the annotations in real time. For example, when mapping data you can view the results of your maps:
At any point in your script you can view your data in the annotations by Using trace() function.
Functions which are called multiple times have a navigation control at the top which lets you select the iteration of the function. See how the for loop mapping kin has a sub window with a navigation control?
See for loop and # Operator on Userdata Objects if these concepts are new to you!
