You're correct: the infinite loop occurs because you're moving up above the pg*footer trap. Since pg*footer calls .BT, and you're spacing up, it gets called again (and again, and again…). So redefining .BT isn't sufficient. You have to adjust the traps. Footer placement is governed by two vertical traps in s.tmac: .wh -\n[FM]u pg@bottom .wh -\n[FM]u/2u pg*footer So it should be possible to pull the footer up by changing the pg*footer trap (untested): .ch pg*footer -\n[FM]u/4u*3u\" place the footer 1/4 of the way down in the margin Note that .ch reverses the order of the parameters from .wh — and that should do what you need. -- Larry
