Hi,

Kindly suggest me how to change packed data in input file.

02 DB-DT-MTH-END PIC 9(5) COMP-3.

DB DT
MTH END
P 3
24-----
*******
-------
X'210F+
200
1F8

When i try to display that variable thru COBOL program it shows as DB-DT-MTH-END: 08213.
Now i want to test the same program for the value 08295. How to change the input file for
obtaining that new value.

Regards
R KARTHIK

Karthik,

How many records you want to update?

Karthik,

If its is only for one or two, you can put a HEX ON and directly edit the file.
For e.g,

Hi,

By doing Hex on is a good idea. Also you can create a copybook for that field.

01 group variable.
02 filler pic x(the length before that field).
02 DB-DT-MTH-END PIC 9(5) COMP-3.
02 filler pic x(the length after the field).

Then Using FILE-AID utility in mainframe the records can be edited.

Thanks,
Lokesh

Can you post your data in ISPF browse mode or view mode with HEX on.

If it is a VSAM, File-aid Browse mode(in CHAR) would do.
