The .1C, .2C, and .MC macros control the number of columns produced in
-ms. See groff_ms(7). I find this works:
(echo .2C; yes '' | awk '{print NR} NR == 1000 {exit}') |
groff -Tutf8 -ms
By default, .2C makes each column 7/15ths of the line length in the LL
number register, with the remainder being the gutter inbetween.
As for the length of each column line, I'd have thought setting the line
length through the \n(LL register may be the easiest way.
(echo .nr LL 10i; echo .2C; yes '' | awk '{print NR} NR == 1000 {exit}') |
groff -Tutf8 -ms
Cheers,
Ralph.
