Hi
This is sasi
interview questions on redefines

1. can we use redefining and redefined variables in one operation ?
ex:

IN A PGM
.
.
.
WORKING STORAGE SECTION.
01 A PIC X(2).
01 B REDEFINES A PIC X(4).
01 C PIC X(4).
PROCEDURE DIVISION.

MOVE 10 TO A.
MOVE 1000 TO B.

COMPUTE C = A+B.
DISPLAY C.
STOP RUN.

the above program works fine(or) not ? if not what error it shows?

2. for the above example
A occupies 2 bytes
B will be occupies 4 bytes
my question how B will be accomdate 4 bytes ?

waiting ur reply

Thanks & Regards
Sasi

Hi Sasi,

It would not abend because Redefines just causes both fields to start at the same location.
I think result should be 1010.
Others plz comment
