Subscripting

Post by chintu1680 » Thu Jul 10, 2008 6:36 pm

Hi,
Can anybody answer this question.

Which of the following statements can not be supported?
(a) subscripting enables us to write a more compact code in the
PROCEDURE DIVISION
(b) subscripting enables us to refer to any element of a table by the
same dataname with the facility of identifying the particular element
through the values of subscripts
(c) subscripting reduces the number of entries to be included in the
DATA DIVISION
(d) subscripting enables us to use loops in the PROCEDURE DIVISION


I feel that all the statements are true
But is the statement (a) is also supported

well think about it:

If you have a table of 10 items, you can mainpulate all ten in a perform loop using subscripting.

whereas if you refer to each item with a unique reference name, you will have approximately 10 times the number of statements as you would with the perform and subscript.

by the way, use INDEXing, much more efficient and saves you from things like, expaning the table from 999 to 1000 itmes and not being able to access the last because your picture for the subscript is only 3.
