Headcell: cell at the negative end (if there is an end),
user-chosen cell rank is a loop.
Uses: floating label for spreadsheet-like views
... other stuff, uh, I don't remember right now.
Plz understand: most of this was designed ca 1984-6;
last year's simplification, and the fun and pain of dealing
with it, have driven quite a bit out of my head.
Maybe next year I can go into the ZZ notes archive ...
back to when it was called GRIDL (Grid Language !-)
