Hi,

To rewrite a record in sequential file we have to first read the record and then give rewrite.

My requirement is if while reading the file End Of File is reached COBOL should start writing new records into the O/P file instead of REWRITE.

So is it possible to give write command after EOF is encountered?

Thanks,
Nirmal

You should NEVER rewrite to a file - if your program fails your output file is corrupted. Write to a new file - maybe a +1 generation otherwise just to another file and rename after successful completion.
