.hh "Italic, Bold, and Underlining"
.fi
The macros \f3.I\fP, \f3.B\fP, and \f3.R\fP are used
to change to, respectively, the italic, bold, and roman fonts
(see examples on pp.\ 4 and 7).
A single argument
given to either \f3.I\fP or \f3.B\fP
results in that argument being printed
in the indicated font.
If two or more arguments are given,
(maximum of 6),
the first is printed in the
indicated font, the second in the prevailing font, etc.,
without any space between them.
The macro \f3.IB\fP prints its successive arguments
alternately in italic
and bold; there are also \f3.BI\fP, \f3.IR\fP, \f3.RI\fP,
\&\f3.RB\fP, and \f3.BR\fP macros.

.hh "Displays"
.fi
Displays are blocks of text that are to
be kept together\(emnot split across pages.
A static display (\f3.DS\fP) appears in the same relative position in
the output text as it does in the input text; this
may result in extra white space at the bottom of a page if a static display is too big to fit
there.
A floating display (\f3.DF\fP),
on the other hand, will ``float'' through the input text
to the top of the next page if there is not enough room for it
on the current page; thus, the text that
\f2follows\^\fP a floating display in the input may \f2precede\^\fP
it in the output.
Displays can be positioned at the left margin,
indented,
or centered.

Macros for a memorandum-style document must be invoked in the order shown
on pp.\ 9-10.
Once the ``memorandum type'' (\f3.MT\fP) macro has been invoked, none of the
macros that precede it can be used.
The \f3.MT\fP macro
controls the format of the ``subject, date, from'' portion of the first
page of the memorandum.
Different arguments to the \f3.MT\fP macro will produce different
kinds of memoranda:

The input and the resulting output for a simple letter
are shown on pp.\ 7-8.
Note that the \f3.TM\fP, \f3.AS\fP/\f3.AE\fP, and \f3.OK\fP macros are \f2not\^\fP
used there, and that the \f3.MT\fP macro has a \f30\fP argument.
A Memorandum for File (MFF) cover sheet may be obtained by
specifying \f3.AS 2\fP.
Notations may appear after the \f3.AE\fP.
Documents of the type shown on pp.\ 2-3 (essentially plain text) are produced
by omitting, as well, all the other ``memorandum-style'' macros:
\&\f3.ND\fP, \f3.TL\fP, \f3.AU\fP, and \f3.MT\fP
at the beginning of the document, and
\&\f3.SG\fP, \f3.NS\fP/\f3.NE\fP, and \f3.CS\fP
at the end.
.sp .5v
Like the \f3.MT\fP macro,
the \f2notations\^\fP macro (\f3.NS\fP) may also take different
arguments to produce a variety of notations following the signature line
or on the MFF cover sheet:

\&\f3.NS 8\fP Letter to
\&\f3.NS 9\fP Memorandum to
.TE
.sp
If the \f3.CS\fP macro is included in the input file
(see last line of p.\ 10)
a technical memorandum cover sheet
is generated
(see p.\ 12).
(The 6 arguments to \f3.CS\fP
which are the data for the bottom of the TM cover
sheet: ``Pages Text,'' ``Other,'' etc., are automatically calculated.)\
The \f3.TC\fP macro,
generates a table of contents;
\&\f3.CS\fP and \f3.TC\fP can occur only at the end of a document.

\f3\-o\fP\f2k\^\fP\f3,\fP\f2m\^\fP\f3\-\fP\f2n\^\fP print only page \f2k\^\fP and pages
\f2m\^\fP through \f2n\^\fP.
\f3\-rC1\fP \f2OFFICIAL FILE COPY\^\fP in footer.
\f3\-rC2\fP \f2DATE FILE COPY\^\fP in footer.
\f3\-rC4\fP \f2DRAFT\^\fP in footer.
\f3\-rL\fP\f2n\^\fP set page length to \f2n\^\fP lines.*
\f3\-rN1\fP page header at \f2bottom\^\fP of first page \f2only\^\fP.
\f3\-rN2\fP no page number on first page.
\f3\-rN3\fP \f2section-page\^\fP numbering.
\f3\-rO\fP\f2n\^\fP set page offset to \f2n\^\fP characters.*
\f3\-rW\fP\f2n\^\fP set line width to \f2n\^\fP characters.*

The \f2mm\^\fP command recognizes the
\f2nroff\^\fP options \f3\-T450\fP, \f3\-T300\fP,
\f3\-T300s\fP, etc., to indicate terminal type;
if such an option is \f2not\^\fP given,
\f2mm\^\fP tries to find the \f3$TERM\fP variable
in the environment.
If no \f3$TERM\fP variable is found,
\f2mm\^\fP will use \f3450\fP as the value of \f3TERM\fP.
The \f3\-12\fP option tells \f2mm\^\fP
to use 12-pitch, if possible.
See Reference\ 6 for details.
