Answer Posted / jkb
Index represents the displacement value of the table entry
from the beginning of the table whereas subscript is the
occurrence number of the table entry.
To calculate the displacement of the table entry from its
beginning when subscript is used takes 16 additional
instructions from the system because of that the usage of
the index is more efficient.
An index can only be modified using PERFORM, SEARCH & SET.
Need to have index for a table in order to use SEARCH,
SEARCH ALL.
