HI,
I have a file which is 100 byte VB. I have a variable defined as S9(04) COMP at byte 20 with value 100. I need to replace the value 100 with 200 which is also a S(04) COMP. Is there a way i can do it with SORT
I use Syncsort.
I thought of OUTREC but i am not sure if i can use outrec with Variable length field.
Thanks
Antony Joseph

Hi,
Think it can be acheived by using OVERLAY statement. If you have any idea other than using OVERLAY please carry out. Do consider the note for VB datasets for any operations.

The first four bytes of each record contain the Record Descriptor Word or RDW, and the first two bytes of the RDW contain the length of that record (in binary). The first data byte of a VB record is in position 5, after the 4-byte RDW in positions 1-4.

Kindly refer the link which could provide some insight. [use of ALTSEQ/TRAN]

Antony,

The below syncsort job should work for your requirement. Taking 4 byte 'RDW' into consideration, the actual data starts at pos-24. Try this and let know if you find any isses.
