I found that Groff and Heirloom handle backslashes in tables differently. I actually think both are wrong, but I am not sure. My input is as follows:
.TS a a . INPUT PRODUCES \\\\ \\ abc def .TE I am processing it with tbl & troff but no macro packages. They produce different results - both unexpected by me. What I am trying to produce is as follows: INPUT PRODUCES \\ \ abc def (Yes, I am using tabs between the columns on the real input file.) Thanks. Blake
