mm - text formatting (memorandum) macros

nroff -mm [options] filename...

troff -mm [options] filename...

This package of nroff(1) and troff(1) macro definitions provides a formatting facility for various styles of articles, theses, and books. When producing 2-column output on a terminal or lineprinter, or when reverse line motions are needed, filter the output through col(1). All external -mm macros are defined below.

Note: this -mm macro package is an extended version written at Berkeley and is a superset of the standard -mm macro packages as supplied by Bell Labs. Some of the Bell Labs macros have been removed; for instance, it is assumed that the user has little interest in producing headers stating that the memo was generated at Whippany Labs.

Many nroff and troff requests are unsafe in conjunction with this package. However, the first four requests below may be used with impunity after initialization, and the last two may be used even before initialization:

.bp

.br

.spn

.cen

.lsn

.na

Font and point size changes with \ef and \es are also allowed; for example, \efIword\efR will italicize word. Output of the tbl(1), eqn(1) and refer(1) preprocessors for equations, tables, and references is acceptable as input.

Here is a table of macros.

Formatting distances can be controlled in -mm by means of built-in number registers. For example, this sets the line length to 6.5 inches:

.nr LL 6.5i

Here is a table of number registers and their default values:

Name	Register Controls	Takes Effect	Default
Cl	contents level	table of contents	2
De	display eject	display	0
Df	display floating	display	5
Ds	display spacing	display	1v
Hb	heading break	heading	2
Hc	heading centering	heading	0
Hi	heading indent	heading	1
Hi	heading spacing	heading	1
Hu	heading unnumbered	heading	2
Li	list indentation	list	6 (nroff) 5 (troff)
Ls	list spacing	list	6
Pi	paragraph indent	paragraph	5
Pt	paragraph type	paragraph	1
Si	static indent	display	5 (nroff) 3 (troff)

When resetting these values, make sure to specify the appropriate units. Setting the line length to 7, for example, will result in output with one character per line. Setting Pi to 0 suppresses paragraph indentation

Here is a list of string registers available in -mm; they may be used anywhere in the text:

Name	String's Function
\e*Q	quote (" in nroff,\| `` in troff )
\e*U	unquote (" in nroff,\| '' in troff )
\e*-	dash (-- in nroff, \(em in troff )
\e*(MO	month (month of the year)
\e*(DY	day (current date)
\e**	automatically numbered footnote
\e*'	acute accent (before letter)
\e*`	grave accent (before letter)
\e*^	circumflex (before letter)
\e*,	cedilla (before letter)
\e*:	umlaut (before letter)
\e*~	tilde (before letter)
\e(BU	bullet item
\e(DT	date (month day, yr)
\e(EM	em dash
\e(Lf	LIST OF FIGURES title
\e(Lt	LIST OF TABLES title
\e(Lx	LIST OF EXHIBITS title
\e(Le	LIST OF EQUATIONS title
\e(Rp	REFERENCES title
\e(Tm	trademark character (TM)

When using the extended accent mark definitions available with .AM, these strings should come after, rather than before, the letter to be accented.

col(1), eqn(1), nroff(1), refer(1), tbl(1), troff(1), attributes(5)

Floating keeps and regular keeps are diverted to the same space, so they cannot be mixed together with predictable results.
