What you are thinking of here is I/O performance. COBOL exposes the  
raw data buffer whereas RPG (default behaviour) copies the data  
buffer into separate fields. This gives COBOL an edge in I/O  
intensive applications. However, as in all things related to  
performance stuff changes on different releases and environments so  
the only way to know for certain is to benchmark. Some people still  
think a MOVE is faster than a Z-ADD.
