Answer Posted / srinivas yadav
-> It is used to reuse the storage space.
example 1:
01 A PIC X(5) VALUE 'SRINU'
01 B PIC X(5).
PROCEDURE DIVISION.
MOVE A TO B.
here we need 10 bytes of memory but in case of redefines
we need only 5 bytes of memory.we can above code by using
redefines like follows
01 A PIC X(5) VALUE 'SRINU'.
01 B REDEFINES A.
-> we can use 01 to 49 level numbers only.
-> in redefines we can use picture clause where as in
renames no need to use picture clause.
-> we have two types of REDEFINES.
1) REDEFINE
2) REDEFINING FIELD.
-> The redefining field can be declared irrespective of
data types.
-> The redefining field length may be is equal,lessthan or
greater than the redefined field.
-> The redefining field should be coded with the same
level number,same group.
-> Immediately followed the redefined or group item.
-> A redefined item cannot redefined.
I think dis is enoug for redefines.
