keep with next para

[Graeme R Forbes]

I have a proof consisting in a sequence of lines across a page, each 
a paragraph, and  each line separated from the next by a shallow 
anchored frame that contains a separator line. Each line/para is set 
to keep with the next one since the whole proof must display on the 
same page. However, in order to get one of the lines to fit across 
the page, I had to use a soft return, and FM allows the proof to 
break across the page at the soft return. Is there some way of 
preventing this while retaining the soft return, or will I have to 
use two paragraphs?

Thanks
Graeme Forbes
