The troff manual says, "a macro to underscore a string can be written .ds us \\$1\l'|0\(ul' .. OK, fine. But what is the |0 in this magic sequence? I don't find it described anywhere... -- Paul DuBois dubois@primate.wisc.edu -- Paul DuBois dubois@primate.wisc.edu

In the beginning of the troff manual, in the section entitled `Numerical parameter input', you will find a paragraph that reads like: The absolute position indicator | may be prepended to a number N to generate the distance to the vertical or horizontal place N. For vertically-oriented requests and functions, |N becomes the distance in basic units from the current vertical place on the page or in a diversion (section 7.4) to the the vertical place N. For all other requests and functions, |N becomes the distance from the current horizontal place on the input line to the horizontal place N Hope this helps, ........ Henry
