Is it possible to get the effect of splitting a box across page boundaries?

Hi,

I'd like a @Box that will split across page boundaries if, say, it is
too large to fit at the bottom of a page, rather than having the whole
box move to the next page.

Has anyone already done this; has anyone got any ideas how to do it (or
is it impossible)?

At the moment I have this:

import @BasicSetup 
def @CodeBox
    named topline{yes}
    named bottomline{yes}
    right x
{
    @Tbl
        rulevertical{yes}
        ruleabove{topline}
        rulebelow{bottomline}
        rulecolor{lightgray}
        rulewidth{1p}
        margin{3p}
        marginbelow{1p}
        break{lines 1vx blanklinescale 0.5}
        font{Venus Base 9p}
        paint{@VeryLightGrey}
        aformat{@Cell width{expand}A}
        strut{no}
    {
        @Rowa A{x}
    }
}
import @BasicSetup def @QG right XYZXYZWWWXYZ{
    @CodeBox {scopeState @Yield @Null}@SetContext{{XYZXYZWWWXYZ @Pipe{}}}
}


I use it like this:

@LD @QG{"lsnip filename @from %to"}

And this gives me a nice box with the extracted lines from the file. But
it won't split across page boundaries because the lines are treated as a
single object in a single row.

I've tried changing the @CodeBox to this:

    def @CodeBox
	...
    {
	@Tbl
	...
	{
	    x
	}
    }

and having my lsnip program return each line wrapped in @Rowa A{} but
lout choked on that.

Thanks!
