Answer / khasim

We can regroup using RENAMES.

02 MM PIC X(2).
02 DD PIC X(2).
02 YY PIC X(2).
66 DATE RENAMES DD TRRU YY.

We can devide an Element to multiple elements using
REDEFINES.

02 DATE1 X(6).
02 DATE2 REDEFINES DATE1.
05 MM PIC X(2).
05 DD PIC X(2).
05 YY PIC X(2).

This is main defference.
Remaining things all know.

Answer / swathi.k

Redefines are used to reuse the storage space where as
renames are used to regroup the elementary items.

Ex:For redefines
01 A.
02 PIC X(6) VALUE 'SWATHI'.
02 REDEFINES A PIC X(2).
fOR RENAMES
01 A.
02 B PIC X(5).
02 C PIC X(5).
02 D.
03 D1 PIC X(2).
03 D2 PIC X(5).
02 E PIC X(6).
66 GROUP1 RENAMES C THRU E.
2.Redefines are coded with 0 to 49 level numbers where
as renames are declared with 66 level no.
3.pic clause is required for redefines where as pic clause
is not used for renames.

Answer / chaitanya chandana

redefines can use the any level no(0-49)...
but renames uses the 66 level no...
redefine may not perform subsequent to earlier data-item.
rename perform subsequent to earlier data-item.
