Hi, I have a requirement to copy data from one PS to another PS by adding a dynamic header and trailer information. my input PS consists of around 200000 records. I hate to read one by one and write to output file just to insert extra header and trailer.

I will really appreciate any suggestion.

PS means "physical sequential", which means you cannot add a header or trailer without reading the entire file and writing it out to another file.

Use plenty of buffers to minimize processing time but expect to read and write every record in the file to achieve your desired result.
