Diez and Jean-Michel,
Ha! Your suggestion above was my *original* coding. It looks like I'm
evolving backwards!
But doesn't it violate the DRY principle? The token excessblk appears
twice instead of once.
Thanks

In this particular case, Richard, I don't think so. The Block class is

I don't see vertical space as such a scarce resource; we don't have an
