Capture the line during the frills processing

Hi

I have a question with frills processing and appreciate if anyone could give me a hand.

We are using XPP 8.4 in Unix. We would like to use XyPerl to capture the line and send back to the division during the frills processing. We are able to open the main stream and access named number registers from a frill block but find difficulty in capturing the line.

Does anyone has an idea on this? Thanks
