184.108.40.206 Multiple columns
The ms macros can set text in as many columns as do reasonably
fit on the page. The following macros are available; all of them force
a page break if a multi-column mode is already set. However, if the
current mode is single-column, starting a multi-column mode does
not force a page break.
— Macro: .1C
— Macro: .2C
— Macro: .MC
Multi-column mode. If you specify no arguments, it is equivalent to the
2C macro. Otherwise, width is the width of each column and
gutter is the space between columns. The
register controls the default gutter width.
