automatically splitting a heading between two frames

[Robert Lauriston]

I've got this working, though it's a kludge.

One of my goals here is to eliminate the need to break documents up
into chapter files, so I can't use <$chapnum>.

For the chapter number, I have a background text frame with a Running
H/F variable defined as <$paranumonly[ChapName]>.

The ChapName autonumber format is <n+>, character format Hidden.

The Hidden character format is 1 point, color white.

This works OK but I'd prefer to actually suppress the ChapName
autonumber if there's some way to do that.
