Hi,
I am facing the problem when trying to REWRITE a VB record into the same file.My requirement is like this.

I am yhaving 2 files.Say A and B

A is a VB file and the file attributes are like below.

Organization . . . : PS
Record format . . . : VB
Record length . . . : 27994
Block size . . . . : 27998


B is a VSAM ksds file.

I need to read the file A and if the value in particular position(in my case it is 101) matches with the file B key values I need to modify the another field in position '121' in first file.

When I try am trying to use the Re write option,it is giving file status 44 error.

It seems I am having the problem in the FD section.Can any body explore on this with some example program?

Thanks

begin0404,

When you are writting a variable block file you need to consider populating the length of the record. And it is advisable to read the record INTO a working storage variable.

ex:

Code:

FD  INPUT-FILE
    RECORDING MODE IS V
    RECORD IS VARYING IN SIZE FROM 10 TO 27994 CHARACTERS
    DEPENDING ON WS-INPUT-LGTH.
01  INPUT-RECORD       PIC  X(27994 ).

WORKING-STORAGE SECTION.

01  WS-LGTH-REC.
    05  WS-INPUT-LGTH  PIC  S9(09) COMP.

01  WS-RECORD          PIC  X(27994 ).

PROCEDURE DIVISION.

READ INPUT-FILE     INTO WS-RECORD.

your processing logic will update the fields in ws-record

REWRITE OUTPUT-RECORD FROM WS-RECORD.



Hope this helps...

Cheers

Kolusu

Hi Kolusu,
I am getting the file mismatch error when I use the FD entries as mentioned by you.

First I got compilation error for S sign in the WS-INPUT-LGTH.
So I removed it and used the PIC X(09) only.Then I compiled it and during running I got the error in file mismatch attributes.The error is

A file attribute mismatch was detected.File INPUT-FILE in program XXXXXX had a record length of 27998.and the file specified in the ASSIGN clause had a record length of 27994.

Then I incread the values to 27998 ,Both in the INPUT-RECORD and
RECORD VARYING CLAUSE INTO 27998,but now the same error came but it is showing the lengths as 28002 and 27994.

Any suggestion?

Thanks

Hi,

I think Kolusu might have been in error when he wrote "27994" in his example code. Try "27990".

Regards, Jack.
