Problems with subsection in a book

[debjani]

I am attaching a test case where the subsection title is at the
bottom of a page, but the text appears on the next page.

I am also attaching the .ps file.

Is there any way to tell lout to always keep the subsection
title and content together in a single page ?

Can anyone help ?

Thanks,
Debjani
