Hi Guys,

Please let me know the answer for the below one:



Which one of the following statements is CORRECT usage of REDEFINE in Cobol ?



1) 01 WS-GROUP.

03 WS-VARIABLE1 OCCURS 5 TIMES PIC X(1) VALUE 'A'.

03 WS-VARIABLE2 REDEFINES WS-VARIABLE1 PIC X(5).



2) 01 WS-GROUP.

03 WS-VARIABLE1 PIC X(5) VALUE 'AAAAA'.

03 WS-VARIABLE2 REDEFINES FILLER-X OCCURS 5 TIMES PIC X(1).



please suggest me....

Thanks,

The data description entry for the redefined item cannot contain an OCCURS clause. However, the redefined item can be subordinate to an item whose data description entry contains an OCCURS clause.

As an example you can declare this.

01 WS-PCT-ALPHA PIC X(07) VALUE 'ABCDEFG'.
01 WS-PCT-ALPHA-R REDEFINES WS-PCT-ALPHA.
10 WS-A PIC X(1) OCCURS 7 TIMES INDEXED BY I.

Actually, both examples are in error. In example 2, FILLER-X is being redefined, but is not itself defined.

2) 01 WS-GROUP.

03 WS-VARIABLE1 PIC X(5) VALUE 'AAAAA'.

03 WS-VARIABLE2 REDEFINES FILLER-X OCCURS 5 TIMES PIC X(1).

The 2nd example works and the 1st one doesn't. (I am assuming that FILLER-X was placed incorrectly and should have been WS-VARIABLE1)

01 WS-GROUP.

03 WS-VARIABLE1 PIC X(5) VALUE 'AAAAA'.

03 WS-VARIABLE2 REDEFINES WS-VARIABLE1 OCCURS 5 TIMES PIC X(1).

Anything/everything works when the code is changed to somethng that is correct. . . We have to reply to what was actually posted icon_wink.gif

If someone asks how some code might be corrected, we can suggest how to change it (like you did).
