Hi ,

I was trying write into sequential file but was getting return code '48'.
Here i have opened sequential file in sequential mode, and opened in I-O mode.
In this program and i read the sequetial file and if certain criteria met then i will add new record in same file.

Can any one pleas suggest how resolve this error.?

Thanks,
Pavan

A file status code 48 (which is what I assume you meant instead of return code '48' -- terminology is critical in IT where similar things may mean very different things, and "return code" only occurs when the program is ended, not on any type of I/O operation) means (from the COBOL Language Reference manual:

Also, why do you want to possibly corrupt your input file by writing to it? Create a new file or be prepared to pay for the extra overhead in recovering your input file.

hi Robert,

Thanks for your time.

While opening the file i am getting status code '00'.
Is there any special consideration i need to take ?..
Even i am able to read the records sucessfully, but only while writing getting isssue.

Are you saying that, for example, you have a 100 record dataset and if the conditions are right when you are record 10 you want to write a record at that point? Well, you cannot as your new record has to go at the end of the file. You can use REWRITE to replace your current record but that is all.

Did you read the COBOL Language Reference manual on the WRITE statement? It starts

Hi Nic,

As per your example, i after reading 10th record, if 10th record matches
certail criterial, then i will adding new record in 11th row.

At this time 11th become 12....at total will be 101 records. No i dont want to write at end.

Thanks,
Pavan.

What you want to do CANNOT be done the way you want to do it -- period.
Writing a new record occurs at the end of the file -- period.

You may open your file for input, open a DIFFERENT file for output, and copy records from input to output, adding records as appropriate, but you cannot write a new 11th record in the existing file without destroying all records after old record number 10.

By the way - you do not add a record at a 'row'. A row is a record in a DB2 table.
