Redefines clause can be used at 01 Level. However the variable you are Redefining must also be declared at the Level. Infact only at 01 level you can redefine a part of the variable instead of having to Redefine for the entire length.

No...redefines Clause cannot be used in 01 level...if it is used in group level items....then redefining the whole group causes the loop to reach infinity and the program abends

hi, sharan

     Normally we are not coding redifine clause in file section, bcoz in the file section if you have more than one 01 level entry system will automatically redefines it implicitly that is called implicit redefination as per my knowledge

REDEFINES can be used @ 01 level.

Ex:

01 TEMP-VAR PIC X(10) VALUE '1234567890'.
01 TEMP-VAR-REF REDEFINES TEMP-VAR.     
   02 FIRST-REF  PIC X(7).              
   02 SECOND-REF PIC 9(3).

yes redefine is possible in 01 level but if group1 & group2 two group items,but any one of them can be in use at a time then we will go for redefine.So if the both the group are using same no. of charectersor of same size.

We CAN use REDEFINES at 01 level  irrespective of the PIC clause of the 2 variables if the REDEFINED variable is also at 01 level.

Hi,

We can redifine a varialbe of 01 level with a variable of another 01 level only.

The redifination can be of any length.

We can redefine at 01 level...

For those who said 'Can't use redefine at 01 level', Please think twice before answering any question.

We cannot use REDEFINE clause on 01 level.

I have tested it and it will give you compilation error.

Redefines clause can be used at 01 level, except that in case if 01 level, data-name-1 cannot exceed data-name-2.

Surely we can use the redefine clause at 01 level, but the only condition is that both the redefined and redefining item should be done at the same level.

*1) USING SAME MEMORY SPACE FOR DIFFERANT ENTRIES.
*2) THE ENTRIES SHOULD BE IN SAME LEVEL.

*3) THE REDEFINS LENGTH OF THE REDEFINED SHOULD BE *LESS, IF 3RD LEVEL HAS COME IMMEDIATLY

*4) THE LENGTH OF THE REDEFIND NEED NOT BE =/>/< ?IN FIRST LEVEL.?
if you code like below it will give error like
*******Original item is smaller than redefinition (5 < 7).

. ?????? IDENTIFICATION DIVISION.
?????? PROGRAM-ID. REDIFINE.
?????? ENVIRONMENT DIVISION.
?????? DATA DIVISION.
?????? WORKING-STORAGE SECTION.
?????? 01 WS-NAME PIC X(16) VALUE IS 'RANAPR'.
?????? 01 WS-OUTNAME REDEFINES WS-NAME.
??????????????? 05 FIRSTNAME PIC? X(6) .
??????????????? 05 LASTNAME PIC X(5).
??????????????? 05 LASTNAM REDEFINES LASTNAME.
?????????????????? 06 AD PIC X(2).
?????????????????? 06 AV PIC X(5).
????? *Original item is smaller than redefinition (5 < 7). :?
?????? PROCEDURE DIVISION.
?????????? DISPLAY WS-NAME.
?????????? MOVE 'RAMANARAJU' TO FIRSTNAME.
?????????? MOVE 'PRATAPSINGH' TO LASTNAME.
?????????? DISPLAY WS-OUTNAME.
?????????? STOP RUN.

Yes, we can use redefines clause in 01 level. You can run this below code it will smoothly runs

User-name required :FOR FILLER
     *USING SAME MEMORY SPACE FOR DIFFERENT ENTRIES.
      IDENTIFICATION DIVISION.
      PROGRAM-ID. REDIFINE.
      ENVIRONMENT DIVISION.
      DATA DIVISION.
      WORKING-STORAGE SECTION.
      01 FILLER PIC X(30).
       01 MYNAME REDEFINES FILLER.
               05 FIRSTNAME
PIC X(14) .
               05 LASTNAME PIC X(15).
      PROCEDURE DIVISION.
          MOVE 'JANARDHAN' TO FIRSTNAME.
          MOVE 'MANCHIKANTI' TO LASTNAME.
          DISPLAY MYNAME.
          STOP RUN.

If you replace filler with some other name like your name, it will work for 01 level.

we can use at 01 level and actually rule of redefines clause: Redefining and redefined fields must be at same level numbers. and for redefining memory must be same or shorter.

The REDEFINES clause can be used when the two data items have the same level number. The exceptions are when the special purpose 66 or 88 level numbers are used and when the level number is at 01 in the FILE SECTION, in which case the a REDEFINES clause cannot be used.

Above details are from the book Structured CObol by Philippakis.

Yes...You can define redefines clause at all levels except 66 and 88 in working-storage section....where as in file section we cant redefine at 01 level..other than this you can...and you cant redefine at occurs clause level...
