<><><> I know about the following *nroff* sequence mapping: <ESC>7 = reverse full vertical <ESC>8 = reverse half vertical <ESC>9 = forward half vertical I am updating my Diablo 630 filter and would like to implement: <ESC>5 = reverse half horizontal <ESC>6 = forward half horizontal I'm not sure if <ESC>5 or <ESC>6 are used, or if the raw nroff formatter does anything to generate some kind of partial horizontal motion. I know how to implement the Diablo side, but I'd like recommendations or pointers on the output (and directives!) from nroff. Randy King AT&T-CP@MG ihnp4!mgweed!rjk

It also describes the width of each individual character, so at least in theory it can support proportional printing. However, its horizontal spacing is done by a combination of space characters and "plot mode" escapes. There is a "narrow space" character but that's it.
