The below post describes about dynamic ASSIGN with INCREMENT variant which is designed for sequential access of memory area that are located at regular intervals after each other like consecutive similar structure components . The RANGE addition helps to define the area in which the INCREMENT is applied.
The ASSIGN with INCREMENT points to the 3rd column = 1st Column + Increment 2
Output:-
The below with WHILE loop with INCREMENT variable accessing the structure components.
Output:-
