Page breaking

[David Miller x4963]

Hi all,
I am nearing the end of my first big document produced with lout and I'm
a bit unsure of the page breaks that are appearing.

I am using a modified version of the book setup.

If I leave the @InitialBreak setting at its default  { adjust 1.2fx hyphen }
I get a few cases of either only the first line of a paragraph at the bottom
of the page, or only the last line at the top of the next page.

I have tried changing @InitialBreak to
{unbreakablefirst unbreakablelast adjust 1.2fx hyphen }

while this has fixed the text in paragraphs, I now get SubSection headings
etc. appearing on their own at the bottom, with the first paragraph on the
next page.

Is there any way of ensuring that a heading stays with at least, say 2 lines
of the first paragraph?

thanks in advance,
David.

p.s.  My modifications to the book setup have only been to change the font
of SubSubSection headings and contents entries.
