Working storage section:-
01 WS-VARX PIC X(9) VALUE SPACES.
01 WS-VARN REDEFINES WS-VARX PIC 9(9).

REDEFINES: It is used to save the memory space....

ur declearing like that ws-varn will take the same memory
of ws-varx...

when u used display statement
DISPLAY WS-VARN
it shows the spaces... WS-VARN will take same memory of WS-
VARX irrespective of data type....

Answer / rookie

if you perform any arithmetic operation than comes the
question of any abend

Answer / ezhilenthi

It wont show any Abend, the main purpose of REDEFINES
clause is to use the same storage area with one or more
data item with different sizes and PIC 's. We will face
Abend if we try to MOVE WS-VARN TO WS-VAR.

WORKING-STORAGE SECTION.
01 WS-VARX PIC X(9) VALUE SPACE.
01 WS-VARN REDEFINES WS-VARX PIC 9(9).
01 I PIC 9(2).
01 J PIC 9(2).
PROCEDURE DIVISION.
MAIN-SECTION.
MAIN-PARA.
MOVE 123456789 TO WS-VARN.
DISPLAY WS-VARN.
STOP RUN.

ON RUN TIME. 123456789
O/P : 123456789

Answer / lalit

I am agreed with Rookie. It will abend if any mathematical
operation like add, subtract will be performed with
variable WS-VARX, but if any mathematical operation is
performed using WS-VARN then it will not abend because it
is numeric in nature.

Answer / ankur

after redefining we can also move alphabetic to numeric or
numeric to alphabetic field . mathematical operation is
different . if we go for that it will give s0c7.

Answer / anna

WORKING-STORAGE SECTION.
01 WS-VARX PIC X(9) VALUE SPACE.
01 WS-VARN REDEFINES WS-VARX PIC 9(9) value zeros.
in this case you can used any data, by using right
field for numeric data ws-varN, for alphabetic /alphanumeric
ws--varX.

Answer / prasanna

Wont it show SOC or ASRA because of the data exception...
(non numeric in a numeric field) ??
