When a table area or record area requires subscripting or indexing, hardware
indexing is employed only if the defined area is less than 16,383 characters.
For a larger area, however, software logic is used for subscripting and
indexing. Thus, subscripting and indexing may be slower if the defined area
is greater than 16, 383 characters.
