REPLACE
Learn REPLACE in ABAP with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.
REPLACE is an atomic ABAP topic inside Expressions & Strings. The example below uses the actual construct named by the lesson rather than a generic placeholder.
Focus on what REPLACE 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
DATA(text) = 'order-OLD'.
REPLACE 'OLD' IN text WITH 'NEW'.
Change the key input in this ABAP example and predict the result first; the named construct should be the reason the behavior changes.
