Answer / siva
yes, we can move accordingly thru REDEFINES clause.
Example :
01 WS-A PIC 9(5).
01 WS-AR REDEFINES WS-A PIC X(5).
01 WS-B PIC A(5).
01 WS-BR REDEFINES WS-B PIC X(5).
MOVE 12345 TO WS-A.
MOVE SPACES TO WS-AR.
MOVE 'ABCDE' TO WS-B.
MOVE ZEROES TO WS-BR.
WS-A, WS-AR contains spaces and WS-B, WS-BR contains
zeroes.

Answer / chakri
Sriram we can move numeric data items to alphanumeric data
items and vice versa. But when we do arithmetic operations
then only it will throw error if we move alphanumeric data
items to numeric items.

Answer / maneendra
Hi all,
I am adding one more point to all.
we can move spaces to numeric field without using redefines
also. it can be possible by Reference modification(The
compiler will then treat your WS-NUM field as alphanumeric.
The field length is not necessary).
sample prog and results are:
IDENTIFICATION DIVISION.
PROGRAM-ID. SPATONUM.
AUTHOR. MANEENDRA.
DATA DIVISION.
WORKING-STORAGE SECTION.
01 WS-NUM PIC 99.
01 WS-STR REDEFINES WS-NUM PIC XX.
PROCEDURE DIVISION.
MOVE ZEROS TO WS-NUM.
DISPLAY 'BEFORE:', WS-NUM.
MOVE SPACES TO WS-NUM(1:).
DISPLAY 'AFTER:', WS-NUM.
STOP RUN.
OUTPUT:
BEFORE:00
AFTER:
For moving numeric field to Alphanumeric field, we can pass
it directly.

Answer / guest
Chakri, you are wrong. Only Numeric data can be moved to
alphanumeric variable. The reverse is not possible.
One way of doing it is using Redefines clause.
| Is This Answer Correct ? | 6 Yes | 5 No |
we can move the numeric to alphanumeric or alphabetic and
vive versa only using the redefines.
this concept is useful when you want to have only one copy
book field need to change to num/aplha for particular
program.

WT R TECHNICAL MAINFRAME QUESTION ASKED IIN ANJANASOFTEARE??
why mainframe we use not like java as frontend oracle as backend. or not word excel.In there also huge ammount data stored.
if a pic 9(3) value 354,b pic x(2) value '46' then a)a>b 2)a<b 3)error
If by mistake we MOVE a working storage variable into LINKAGE area. What will happen??
Consider the following code: 77 A PIC 99V99 VALUE 55.35 77 B PIC 99V999 VALUE 32.754 ADD B TO A ON SIZE ERROR DISPLAY "ERROR!!!" What will be the result ? (a) A=88.10, B=32.754 (b) A=87.00 B=32.754 (c) A=87.10 B=32.754 (d) ERROR!!! will be DISPLAYed on the screen.
