WHILE is an atomic ABAP topic inside Control Flow. The example below uses the actual construct named by the lesson rather than a generic placeholder.
Focus on what WHILE changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.
Topic-specific example

Try It Live
DATA n TYPE i VALUE 3.
WHILE n > 0. WRITE n. n -= 1. ENDWHILE.
Edge case / engineering note
Change the key input in this ABAP example and predict the result first; the named construct should be the reason the behavior changes.
