Hi,

I have a dataset which contains 4 lac records. If I try to open it browse is substituted. Is there any way to open it in edit mode. I need to update the record count in trailer record. We do not have a file-aid in out shop.

Thanks in advance

Cheers!!!
Nadh

You are limited by the space set by your session. You can not use ISPF to edit large files.

1) You can use sort to modify the trailer record.

2) you can use sort to drop the original trailer and add a new trailer record.

3) If you know exactly how many records are in the DS, and know exactly what you want to change in your trailer record, you can use 3.3, and copy all but the last record (trailer record) to a new DS. use 3.3 to copy only the last record to a another new DS. Edit the second dataset and modify the trailer record. Then use 3.3 to copy the concatenated new DSs over the original.

I would only use method 3 if you can't get a sort solution from someone.
