GROFF_MM(7) MachTen Programmer’s Manual GROFF_MM(7)

NAME
groff_mm - groff mm macros

SYNOPSIS
groff -mm [ options... ] [ files... ]

DESCRIPTION
The groff mm macros are intended to be compatible with the
DWB mm macros with the following limitations:

o no Bell Labs localisms implemented.

o the macros OK and PM is not implemented.

o groff mm does not support cut marks

mm is intended to be international. Therefore it is possi-
ble to write short national macrofiles which change all
english text to the preferred language. Use mmse as an
example.

New macros: APP, APPSK, B1, B2, BVL, COVER, COVEND, GETHN,
GETPN, GETR, GETST, INITR, MC, MOVE, MULB, MULN, MULE,
PGFORM, PGNH, SETR, TAB, VERBON, VERBOFF.

A file called locale or lang_locale is read after the ini-
tiation of the global variables. It is therefore possible
to localize the macros with companyname and so on.

In this manual square brackets is used to show optional
arguments.

Number registers and strings
Many macros can be controlled by number registers and
strings. A number register is assigned with the nr com-
mand:
.nr XXX [+-]n [i]
XXX is the name of the register, n is the value to be
assigned, and i is increment value for auto-increment. n
can have a plus or minus sign as prefix if an increment or
decrement of the current value is wanted. (Auto-increment
or decrement occurs if the number register is used with a
plus or minus sign,n+[XXX] orn-[XXX].)

Strings is defined with ds.
.ds YYY string
The string is assigned everything to the end of the line,
even blanks. Initial blanks in string should be prefixed
with a double-quote. (Strings are used in the text as
*[YYY].)

Special formatting of number registers A number register
is printed with normal digits if no format has been given.
Set the format with af:
.af R c
R is the name of the register, c is the format.

Form Sequence
1 0, 1, 2, 3, ...
001 000, 001, 002, 003, ...
i 0, i, ii, iii, iv, ...
I 0, I, II, III, IV, ...
a 0, a, b, c, ..., z, aa, ab, ...
A 0, A, B, C, ..., Z, AA, AB, ...

Macros:

1C [1] Begin one column processing. An 1 as argument dis-
ables the page-break. Use wide footnotes, small
footnotes may be overprinted.

2C Begin two column processing. Splits the page in two
columns. It is a special case of MC. See also 1C.

AE Abstract end, see AS.

AF [name of firm]
Authors firm, should be called before AU, see also
COVER.

AL [type [text-indent [1]]]]
Start autoincrement list. Items are numbered begin-
ning on one. The type argument controls the type
of numbers.
Arg Description
1 Arabic (the default)
A Upper-case letters (A-Z)
a Lower-case letters (a-z)
I Upper-case roman
i Lower-case roman
Text-indent sets the indent and overrides Li. A
third argument will prohibit printing of a blank
line before each item.

APP name text
Begin an appendix with name name. Automatic naming
occurs if name is "". The appendixes starts with A
if auto is used. An new page is ejected, and a
header is also produced if the number variable Aph
is non-zero. This is the default. The appendix
always appear in the ’List of contents’ with cor-
rect pagenumber. The name APPENDIX can be changed
by setting the string App to the desired text.

APPSK name pages text
Same as .APP, but the pagenr is incremented with
pages. This is used when diagrams or other non-
formatted documents are included as appendixes.

AS [arg [indent]]
Abstract start. Indent is specified in ’ens’, but
scaling is allowed. Argument arg controls where
the abstract is printed.
Arg Placement
0 Abstract will be printed on page 1 and con the
cover sheet if used in the released-paper
style (MT 4), otherwise it will be printed on
page 1 without a cover sheet.
1 Abstract will only be printed on page 1 (MT 4
only).
2 Abstract will be printed only on the cover
sheet. The cover sheet is printed without need
for CS.
Abstract is not printed at all in external letters
(MT 5). The indent controls the indentation of
both margins, otherwise will normal text indent be
used.

AST [title]
Abstract title. Default is ABSTRACT. Sets the text
above the abstract text.

AT title1 [title2 ...]
Authors title. AT must appear just after each AU.
The title will show up after the name in the signa-
ture block.

AU name [initials [loc [dept [ext [room [arg [arg
[arg]]]]]]]]
Author information, specifies the author of the
memo or paper, and will be printed on the cover
sheet and on other similar places. AU must appear
before TL. The author information can contain
intials, location, department, telephone extension,
room number or name and up to three extra argu-
ments.

AV [name [1]]
Approval signature, generates an approval line with
place for signature and date. The string APPROVED:
can be changed with variable Letapp, and the string
Date in Letdate.

B [bold-text [prev-font-tex [bold...]]]
Begin boldface No limit on the number of arguments.
All arguments will be concatenated to one word, the
first, third and so on will be printed in boldface.

B1 Begin box (as the ms macro) Draws a box around the
text. The text will be indented one character, and
the right margin will be one character shorter.

B2 End box. Finish the box started by B1.

BE End bottom block, see BS.

BI [bold-text [italic-text [bold-text [...]]]
Bold-italic. No limit on the number of arguments,
see B.

BL [text-indent [1]]
Start bullet list, initialize a list with a bullet
and a space in the beginning of each list item (see
LI). Text-indent overrides the default indentation
of the list items set by number register Pi. A
third argument will prohibit printing of a blank
line before each item.

BR [bold-text [roman-text [bold-text [...]]]
Bold-roman. No limit on the number of arguments.

BS Bottom block start. Begins the definition of a text
block wich is printed at the bottom of each page.
Block ends with BE.

BVL Start of broken variable-item list. Broken vari-
able-item list has no fixed mark, it assumes that
every LI has a mark instead. The text will always
begin at the next line after the mark. Text-indent
sets the indent to the text, and mark-indent the
distance from the current indent to the mark. A
third argument will prohibit printing of a blank
line before each item.

COVER [arg]
COVER begins a coversheet definition. It is impor-
tant that .COVER appears before any normal text.
.COVER uses arg to build the filename
/usr/share/groff/tmac/mm/arg.cov. Therefore it is
possible to create unlimited types of coversheets.
ms.cov is supposed to look like the ms coversheet.
.COVER requires a .COVEND at the end of the
coverdefinition. Always use this order of the cov-
ermacros:
.COVER
.TL
.AF
.AU
.AT
.AS
.AE
.COVEND
However, only .TL and .AU are required.

COVEND This finish the cover description and prints the
cover-page. It is defined in the cover file.

DE Display end. Ends a block of text, display, that
begins with DS or DF.

DF [format [fill [rindent]]]
Begin floating display (no nesting allowed). A
floating display is saved in a queue and is printed
in the order entered. Format, fill and rindent is
the same as in DS. Floating displays are con-
trolled by the two number registers De and Df.

De register
0 Nothing special, this is the default.
1 A page eject will occur after each printed
display, giving only one display per page and
no text following it.

Df register
0 Displays are printed at the end of each sec-
tion (when section-page numbering is active)
or at the end of the document.
1 A new display will be printed on the current
page is there is enough space, otherwise it
will be printed at the end of the document.
2 One display will be printed at the top of each
page or column (in multi-column mode).
3 Print one display if there is enough space for
it, otherwise it will be printed at the top of
the next page or column.
4 Print as many displays that will fit in a new
page or column. A page break will occur
between each display if De is not zero.
5 Fill the current page with displays and the
rest beginning at a new page or column. (This
is the default.) A page break will occur
between each display if De is not zero.

DL [text-indent [1]]
Dash list start. Begins a list where each item is
printed after a dash. Text-indent changes the
default indentation of the list items set by number
register Pi. A third argument will prohibit print-
ing of a blank line before each item. A second
argument prevents the empty line between each list
item to be printed. See LI.

DS [format [fill [rindent]]]
Static display start. Begins collection of text
until DE. The text is printed together on the same
page, unless it is longer than the height of the
page. DS can be nested to a unlimited depth (rea-
sonably :-).

format
"" No indentation.
none No indentation.
L No indentation.
I Indent text with the value of number register
Si.
C Center each line
CB Center the whole display as a block.
R Right adjust the lines.
RB Right adjust the whole display as a block

L, I, C and CB can also be specified as 0, 1, 2 or
3 for compatibility reasons. (Don’t use it. :-)

fill
"" Line-filling turned off.
none Line-filling turned off.
N Line-filling turned off.
F Line-filling turned on.

N and F can also be specified as 0 or 1. An empty
line will normally be printed before and after the
display. Setting number register Ds to 0 will pre-
vent this. Rindent shortens the line length by
that amount.

EC [title [override [flag [refname]]]]
Equation title. Sets a title for an equation. The
override argument change the numbering.

flag
none override is a prefix to the number.
0 override is a prefix to the number.
1 override is a suffix to the number.
2 override replaces the number.
EC uses the number register Ec as counter. It is
possible to use .af to change the format of the
number. If number register Of is 1, then the for-
mat of title will use a dash instead of a dot after
the number. The string Le controls the title of
the List of Equations, default is LIST OF EQUA-
TIONS. The string Liec contains the word Equation,
wich is printed before the number. If refname is
used, then the equationnumber is saved with .SETR,
and can be retrieved with .GETST refname.

EF [arg]
Even-page footer, printed just above the normal
page footer on even pages, see PF.

EH [arg]
Even-page header, printed just below the normal
page header on even pages, see PH.

EN Equation end, see EQ.

EOP End of page user-defined macro. This macro will be
called instead of the normal printing of the
footer. The macro will be executed in a separate
environment, without any trap active. See TP.

Strings available to EOP
EOPf Argument from PF.
EOPefArgument from EF.
EOPofArgument from OF.

EQ [label]
Equation start. EQ/EN are the delimiters for equa-
tions written for eqn. EQ/EN must be inside a
DS/DE-pair, except when EQ is only used to set
options in eqn. The label will appear at the right
margin of the equation, unless number register Eq
is 1. Then the label will appear at the left mar-
gin.

EX [title [override [flag [refname]]]]
Exhibit title, arguments are the same as for EC EX
uses the number register Ex as counter. The string
Lx controls the title of the List of Exhibits,
default is LIST OF EXHIBITS. The string Liex con-
tains the word Exhibit, wich is printed before the
number. If refname is used, then the exhibitnumber
is saved with .SETR, and can be retrieved with
.GETST refname.

FC [closing]
Prints Yours very truly, as a formal closing of a
letter or memorandum. The argument replaces the
defualt string. The default is stored in string
variable Letfc.

FD [arg [1]]
Footnote default format. Controls the hyphenation
(hyphen), right margin justification (adjust),
indentation of footnote text (indent). It can also
change the label justification (ljust).

arg hyphen adjust indent ljust
0 no yes yes left
1 yes yes yes left
2 no no yes left
3 yes no yes left
4 no yes no left
5 yes yes no left
6 no no no left
7 yes no no left
8 no yes yes right
9 yes yes yes right
10 no no yes right
11 yes no yes right

Argument greater than or equal to 11 is considered
as arg 0. Default for mmm is 10.

FE Footnote end.

FG [title [override [flag [refname]]]]
Figure title. If refname is used, then the fig-
urenumber is saved with .SETR, and can be retrieved
with .GETST refname.

FS [label]
Footnote start. The footnote is ended by FE. Foot-
notes is normally automatically numbered, the num-
ber is available in string F. Just add*F in the
text. By adding label, it is possible to have other
number or names on the footnotes. Footnotes in
displays is now possible. An empty line separates
footnotes, the height of the line is controlled by
number register Fs, default value is 1.

GETHN refname [varname]
Includes the headernumber where the corresponding
SETR refname was placed. Will be X.X.X. in pass 1.
See INITR. If varname is used, GETHN sets the
stringvariable varname to the headernumber.

GETPN refname [varname]
Includes the pagenumber where the corresponding
SETR refname was placed. Will be 9999 in pass 1.
See INITR. If varname is used, GETPN sets the
stringvariable varname to the pagenumber.

GETR refname
Combines GETHN and GETPN with the text ’chapter’
and ’, page’. The string Qrf contains the text for
reference:
.ds Qrf See chapter \*[Qrfh], page \*[Qrfp].
Qrf may be changed to support other languages.
Strings Qrfh and Qrfp are set by GETR and contains
the page and headernumber.

GETST refname [varname]
Includes the string saved with the second argument
to .SETR. Will be dummystring in pass 1. If var-
name is used, GETST sets the stringvariable varname
to the saved string. See INITR.

H level [heading-text [heading-suffix]]
Numbered section heading. Section headers can have
a level between 1 and 7, level 1 is the top level.
The text is given in heading-text, and must be sur-
rounded by double quotes if it contains spaces.
Heading-suffix is added to the header in the text
but not in the table of contents. This is normally
used for footnote marks and similar things. Don’t
use*F in heading-suffix, it won’t work. A manual
label must be used, see FS.

An eventual paragraph, P, directly after H will be
ignored, H is taking care of spacing and indenta-
tion.

Page ejection before heading
Number register Ej controls page ejection before
the heading. Normally, a level one heading gets
two blank lines before it, higher levels gets only
one. A new page is ejected before each first-level
heading if number register Ej is 1. All levels
below or equal the value of Ej gets a new page.
Default value for Ej is 0.

Heading break level
A line break occurs after the heading if the head-
ing level is less or equal to number register Hb.
Default value 2.

Heading space level
A blank line is inserted after the heading if the
heading level is less or equal to number register
Hs. Default value 2.

Text will follow the heading on the same line if
the level is greater than both Hb and Hs.

Post-heading indent
Indentation of the text after the heading is con-
trolled by number register Hi, default value 0. Hi
0 The text will be left-justified.
1 Indentation of the text will follow the value
of number register Pt, see P.
2 The text will be lined up with the first word
of the heading.

Centered section headings
All headings whose level is equal or below number
register Hc and also less than or equal to Hb or Hs
is centerered.

Font control of the heading
The font of each heading level is controlled by
string HF. It contains a fontnumber or fontnam for
each level. Default is 2 2 2 2 2 2 2 (all headings
in italic). Could also be written as
I I I I I I I. All omitted values are presumed to
be a 1.

Point size control.
String HP controls the pointsize of each heading,
in the same way as HF controls the font. A value
of 0 selects the default point size. Default value
is 0 0 0 0 0 0 0. Beware that only the point size
changes, not the vertical size. That can be con-
trolled by the user specified macro HX and/or HZ.

Heading counters
Seven number registers, named H1 thru H7 contains
the counter for each heading level. The values are
printed using arabic numerals, this can be changed
with the macro HM (see below). All marks ar con-
catenated before printing. To avoid this, set num-
ber register Ht to 1. That will only print the cur-
rent heading counter at each heading.

Automatic table of contents
All headings whose level is equal or below number
register Cl is saved to be printed in the table of
contents. Default value is 2.

Special control of the heading, user-defined
macros.
These macros can be defined by the user to get a
finer control of vertical spacing, fonts or other
features. Argument level is the level-argument to
H, but 0 for unnumbered headings (see HU). Argu-
ment rlevel is the real level, it is set to number
register Hu for unnumbered headings. Argument
heading-text is the text argument to H and HU.

HX level rlevel heading-text
HX is called just before the printing of the head-
ing. The following register is available for HX.
HX may alter }0, }2 and ;3.
string }0
Contains the heading mark plus two spaces if
rlevel is non-zero, otherwise empty.
register ;0
Contains the position of the text after the
heading. 0 means that the text should follow
the heading on the same line, 1 means that a
line break should occur before the text and 2
means that a blank line should separate the
heading and the text.
string }2
Contains two spaces if register ;0 is 0. It is
used to separate the heading from the text.
The string is empty if ;0 is non-zero.
register ;3
Contains the needed space in units after the
heading. Default is 2v.

Can be used to change things like numbering
(}0), vertical spacing (}2) and the needed
space after the heading.

HY dlevel rlevel heading-text
HY is called after size and font calculations and
might be used to change indentation.

HZ dlevel rlevel heading-text HZ is called after
the printing of the heading, just before H or HU
exits. Could be used to change the page header
according to the section heading.

HC [hyphenation-character]
Set hyphenation character. Default value is .
Resets to the default if called without argument.
Hyphenation can be turned by setting number regis-
ter Hy to 0 in the beginning of the file.

HM [arg1 [arg2 [... [arg7]]]]
Heading mark style. Controls the type of marking
for printing of the heading counters. Default is 1
for all levels.

Argument
1 Arabic numerals.
0001 Arabic numerals with leading zeroes, one or
more.
A Upper-case alphabetic
a Lower-case alphabetic
I Upper-case roman numerals
i lower-case roman numerals
emptyArabic numerals.

HU heading-text
Unnumbered section header. HU behavies like H at
the level in number register Hu. See H.

HX dlevel rlevel heading-text
Userdefined heading exit. Called just before
printing the header. See H.

HY dlevel rlevel heading-text
Userdefined heading exit. Called just before
printing the header. See H.

HZ dlevel rlevel heading-text
Userdefined heading exit. Called just after print-
ing the header. See H.

I [italic-text [prev-font-text [italic-text [...]]]
Italic. Changes the font to italic if called with-
out arguments. With one argument it will set the
word in italic. With two argument it will concate-
nate them and set the first word in italic and the
second in the previous font. There is no limit on
the number of argument, all will be concatenated.

IA [addressee-name [title]]
Begins specification of the addressee and
addressee’s address in letter style. Several names
can be specified with empty IA/IE-pairs, but only
one address. See LT.

IB [italic-text [bold-text [italic-text [...]]]
Italic-bold Even arguments is printed in italic,
odd in boldface. See I.

IE Ends the address-specification after IA.

INITR filename
Initialize the refencemacros. References will be
written to filename.tmp and filename.qrf. Requires
two passes with groff. The first looks for refer-
ences and the second includes them. INITR can be
used several times, but it is only the first occur-
rence of INITR that is active. See also SETR,
GETPN and GETHN.

IR [italic-text [roman-text [italic-text [...]]]
Italic-roman Even arguments is printed in italic,
odd in roman. See I.

LB text-indent mark-indent pad type [mark [LI-space [LB-
space]]]
List begin macro. This is the common macro used
for all lists. Text-indent is the number of spaces
to indent the text from the current indent.

Pad and mark-indent controls where to put the mark.
The mark is placed within the mark area, and mark-
indent sets the number of spaces before this area.
It is normally 0. The mark area ends where the
text begins. The start of the text is still con-
trolled by text-indent.

The mark is left justified whitin the mark area if
pad is 0. If pad is greater than 0, then mark-
indent is ignored, and the mark is placed pad
spaces before the text. This will right justify
the mark.

If type is 0 the list will have either a hanging
indent or, if argument mark is given, the string
mark as mark.

If type is greater than 0 automatic numbering will
occur, arabic if mark is empty. Mark can then be
any of 1, A, a, I or i.

Type selects one of six possible ways to display
the mark.
type
1 x.
2 x)
3 (x)
4 [x]
5 <x>
6 {x}

Every item in the list will get LI-space number of
blank lines before them. Default is 1.

LB itself will print LB-space blank lines. Default
is 0.

LC [list-level]
List-status clear Terminates all current active
lists down to list-level, or 0 if no argmuent is
given. This is used by H to clear any active list.

LE [1] List end. Terminate the current list. LE outputs a
blank line if an argument is given.

LI [mark [1]]
List item precedes every item in a list. Without
argument LS will print the mark determined by the
current list type. By giving LI one argument, it
will use that as the mark instead. Two arguments
to LI will make mark a prefix to the current mark.
A zero length mark will make a hanging indent
instead.

A blank line is normally printed before the list
item. This behaviour can be controlled by number
register Ls. Pre-spacing will occur for each list-
level less than or equal to Ls. Default value is
99. (Nesting of lists is unlimited. :-)

The indentation can be changed thru number register
Li. Default is 6.

All lists begins with a list initialization macro,
LB. There are, however, seven predefined listtypes
to make lists easier to use. They all call LB with
different default values.
AL Automatically Incremented List
ML Marked List
VL Variable-Item List
BL Bullet List
DL Dash List
RL Reference List
BVL Broken Varable List.
These lists are described at other places in this
manual. See also LB.

LT [arg]
Formats a letter in one of four different styles
depending on the argument. See also INTERNALS.
Arg Style
BL Blocked. Date line, return address, writer’s
address and closing begins at the center of
the line. All other lines begins at the left

margin.
SB Semi-blocked. Same as blocked, except that the
first line in every paragraph is indented five
spaces.
FB Full-blocked. All lines begin at the left mar-
gin.
SP Simplified. Almost the same as the full-
blocked style. Subject and the writer’sidenti-
fication is printed in all-capital.

LO type [arg]
Specify options in letter (see .LT). This is a
list of the standard options:
CN Confidential notation. Prints RESTRICTED on
the second line below the date line. Any argu-
ment replaces RESTRICTED. See also string
variable LetCN.
RN Reference notation. Prints In reference to:
and the argument two lines below the date
line. See also string variable LetRN.
AT Attention. Prints ATTENTION: and the argument
below the inside address. See also string
variable LetAT.
SA Salutation. Prints To Whom It May Concern: or
the argument if it was present. The salutation
is printed two lines below the inside address.
See also string variable LetSA.
SJ Subject line. Prints the argument as subject
prefixed with SUBJECT: two lines below the
inside address, except in letter type SP.
Then the subject is printed in all-captial
without any prefix. See also string variable
LetSJ.

MC column-size [column-separation]
Begin multiple columns. Return to normal with 1C.
MC will create as many columns as the current line
length permits. Column-size is the width of each
column, and column-separation is the space between
two columns. Default separation is the column-
size/15. See also 1C.

ML mark [text-indent [1]]
Marked list start. The mark argument will be
printed before each list item. Text-indent sets
the indent and overrides Li. A third argument will
prohibit printing of a blank line before each item.

MT [arg [addressee]]
Memorandum type. The arg is part of a filename in
/usr/share/groff/tmac/mm/*.MT. Memorandum type 0
thru 5 are supported, including "string". Addresse
just sets a variable, used in the AT&T macros.
arg
0 Normal memorandum, no type printed
1 Memorandum with MEMORANDUM FOR FILE printed
2 Memorandum with PROGRAMMER’S NOTES printed
3 Memorandum with ENGINEER’S NOTES printed
4 Released paper style
5 External letter style
See also COVER/COVEND, a more flexible type of
front page.

MOVE y-pos [x-pos [line-length]]
Move to a position, pageoffset set to x-pos. If
line-length is not given, the difference between
current and new pageoffset is used. Use PGFORM
without arguments to return to normal.

MULB cw1 space1 [cw2 space2 [cw3 ...]]
Begin a special multi-column mode. Every columns
width must be specified. Also the space between
the columns must be specified. The last column does
not need any space-definition. MULB starts a diver-
sion and MULE ends the diversion and prints the
columns. The unit for width and space is ’n’, but
MULB accepts all normal unitspecifications like ’c’
and ’i’. MULB operates in a separate environment.

MULN Begin the next column. This is the only way to
switch column.

MULE End the multi-column mode and print the columns.

nP [type]
Print numbered paragraph with header level two. Se
.P.

NS [arg [1]]
Prints different types of notations. The argument
selects between the predefined type of notations.
If the second argument is available, then the argu-
ment becomes the entire notation. If the argument
doesn’t exist in the predefined, it will be printed
as Copy (arg) to. It is possible to add more stan-
dard notations, see the string variable Letns and
Letnsdef.
Arg Notation
none Copy To
"" Copy To
1 Copy To (with att.) to
2 Copy To (without att.) to
3 Att.
4 Atts.
5 Enc.
6 Encs.
7 Under separate cover
8 Letter to
9 Memorandum to
10 Copy (with atts.) to
11 Copy (without atts.) to
12 Abstract Only to
13 Complete Memorandum to
14 CC

ND new-date
New date. Override the current date. Date is not
printed if new-date is an empty string.

OF [arg]
Odd-page footer, a line printed just above the nor-
mal footer. See EF and PF.

OH [arg]
Odd-page header, a line printed just below the nor-
mal header. See EH and PH.

OP Make sure that the following text is printed at the
top of an odd-numbered page. Will not output an
empty page if currently at the top of an odd page.

P [type]
Begin new paragraph. P without argument will pro-
duce left justified text, even the first line of
the paragraph. This is the same as setting type to
0. If the argument is 1, then the first line of
text following P will be indented by the number of
spaces in number register Pi, normally 5.

Instead of giving 1 as argument to P it is possible
to set the paragraph type in number register Pt.
Using 0 and 1 will be the same as adding that value
to P. A value of 2 will indent all paragraphs,
except after headings, lists and displays.

The space between two paragraphs is controlled by
number register Ps, and is 1 by default (one blank
line).

PGFORM [linelength [pagelength [pageoffset [1]]]]
Sets linelength, pagelength and/or pageoffset.
This macro can be used for special formatting, like
letterheads and other. It is normally the first
command in a file, though it’s not necessary.
PGFORM can be used without arguments to reset
everything after a MOVE. A line-break is done
unless the fourth argument is given. This can be
used to avoid the pagenumber on the first page
while setting new width and length.

PGNH No header is printed on the next page. Used to get
rid off the header in letters or other special
texts This macro must be used before any text to
inhibit the pageheader on the first page.

PE Picture end. Ends a picture for pic, see the man-
ual for pic.

PF [arg]
Page footer. PF sets the line to be printed at the
bottom of each page. Normally empty. See PH for
the argument specification.

PH [arg]
Page header, a line printed at the top of each
page. The argument should be specified as "’left-
part’center-part’right-part’", where left-, center-
and right-part is printed left-justified, centered
and right justified. The character % is changed to
the current page number. The default page-header is
"’’- % -’’", the page number between two dashes.

PS Picture start (from pic). Begins a picture for
@TMAC@pic, see the manual.

PX Page-header user-defined exit. PX is called just
after the printing of the page header in no-space
mode.

R Roman. Return to roman font, see also I.

RB [roman-text [bold-text [roman-text [...]]]
Roman-bold. Even arguments is printed in roman,
odd in boldface. See I.

RD [prompt [diversion [string]]]
Read from standard input to diversion and/or
string. The text will be saved in a diversion
named diversion. Recall the text by writing the
name of the diversion after a dot on an empty line.
A string will also be defined if string is given.
Diversion and/or prompt can be empty ("").

RF Reference end. Ends a reference definition and
returns to normal processing. See RS.

RI [roman-text [italic-text [roman-text [...]]]
Even arguments is printed in roman, odd in italic.
See I.

RL [text-indent [1]]
Reference list start Begins a list where each item
is preceded with a automatically incremented number
between square brackets. Text-indent changes the
default indentation

RP [arg1 [arg2]]
Produce reference page. RP can be used if a refer-
ence page is wanted somewhere in the document. It
is not needed if TC is used to produce a table of
content. The reference page will then be printed
automatically.

The reference counter will not be resetted if arg1
is 1.

Arg2 tells RP whether to eject a page or not.
Arg2
0 The reference page will be printed on a sepa-
rate page. This is the default.
1 Do not eject page after the list.
2 Do not eject page before the list.
3 Do not eject page before and after the list.
The reference items will be separated by a blank
line. Setting number register Ls to 0 will sup-
press the line.

The string Rp contains the reference page title and
is normally set to REFERENCES.

RS [string-name]
RS begins an automatically numbered reference defi-
nition. Put the string*(Rf where the reference
mark should be and write the reference between
RS/RF at next new line after the reference mark.
The reference number is stored in number register
:R. If string-name is given, a string with that
name will be defined and contain the current refer-
ence mark. The string can be referenced as
*[string-name] later in the text.

S [size [spacing]]
Set point size and vertical spacing. If any argu-
ment is equal ’P’, then the previous value is used.
A ’C’ means current value, and ’D’ default value.
If ’+’ or ’-’ is used before the value, then incre-
ment or decrement of the current value will be
done.

SA [arg]
Set right-margin justification. Justification is
normally turned on. No argumenent or 0 turns off
justification, a 1 turns on justification.

SETR refname [string]
Remember the current header and page-number as ref-
name. Saves string if string is defined. string is
retrieved with .GETST. See INITR.

SG [arg [1]]
Signature line. Prints the authors name(s) after
the formal closing. The argument will be appended
to the reference data, printed at either the first
or last author. The reference data is the location,
department and initials specified with .AU. It
will be printed at the first author, otherwise at
the last. No reference data will be printed if the
author(s) is specifed thru .WA/.WE. See Letter
internals.

SK [pages]
Skip pages. If pages is 0 or omitted, a skip to
the next page will occur unless it is already at
the top of a page. Otherwise it will skip pages
pages.

SM string1 [string2 [string3]]
Make a string smaller. If string2 is given,
string1 will be smaller and string2 normal, con-
catenated with string1. With three argument, all is
concatenated, but only string2 is made smaller.

SP [lines]
Space vertically. lines can have any scalingfactor,
like 3i or 8v. Several SP in a line will only pro-
duce the maximum number of lines, not the sum. SP
will also be ignored until the first textline in a
page. Add & before SP to avoid this.

TAB reset tabs to every 5n. Normally used to reset any
previous tabpositions.

TB [title [override [flag [refname]]]]
Table title. If refname is used, then the
tablenumber is saved with .SETR, and can be
retrieved with .GETST refname.

TC [slevel [spacing [tlevel [tab [h1 [h2 [h3 [h4
[h5]]]]]]]]]
Table of contents. This macro is normally used at
the last line of the document. It generates a
table of contents with headings up to the level
controlled by number register Cl. Note that Cl con-
trols the saving of headings, it has nothing to do
with TC. Headings with level less than or equal to
slevel will get spacing number of lines before
them. Headings with level less than or equal to
tlevel will have their page numbers right justified
with dots or spaces separating the text and the
page number. Spaces is used if tab is greater than
zero, otherwise dots. Other headings will have the
page number directly at the end of the heading text
(ragged right).

The rest of the arguments will be printed, cen-
tered, before the table of contents.

The user-defined macros TX and TY are used if TC is
called with at most four arguments. RX is called
before the printing of CONTENTS, and TY is called
instead of printing CONTENTS.

String Ci can be set to control the indentations
for each heading-level. It must be scaled, like
.ds Ci .25i .5i .75i 1i 1i. The indentation is
normally controlled by the maxlength of headings in
each level.

All texts can be redefined, new stringvariables
Lifg, Litb, Liex, Liec and Licon contains "Figure",
"TABLE", "Exhibit", "Equation" and "CONTENTS".
These can be redefined to other languages.

TE Table end. See TS.

TH [N] Table header. See TS. TH ends the header of the
table. This header will be printed again if a page-
break occurs. Argument N isn’t implemented yet.

TL [charging-case number(s) [filing-case number(s)]
Begin title of memorandum. All text up to the next
AU is included in the title. Charging-case number
and filing-case is saved for use in the front page
processing.

TM [num1 [num2 [...]]]
Technical memorandumnumbers used in .MT. Unlimited
number of arguments may be given.

TP Top of page user-defined macro. This macro is
called instead of the normal page header. It is
possible to get complete control over the header.
Note that header and footer is printed in a sepa-
rate environment. Linelength is preserved though.

TS [H] Table start. This is the start of a table specifi-
cation to @TMAC@tbl. See separate manual for
@TMAC@tbl. TS ends with TE. Argument H tells
m@TMAC@m that the table has a header. See TH.

TX Userdefined table of contents exit. This macro is
called just before TC prints the word CONTENTS.
See TC.

TY Userdefined table of contents exit (no "CONTENTS").
This macro is called instead of printing CONTENTS.
See TC.

VERBON [flag [pointsize [font]]]
Begin verbatim output using courier font. Usually
for printing programs. All character has equal
width. The pointsize can be changed with the sec-
ond argument. By specifying the font-argument it is
possible to use another font instead of courier.
flag control several special features. It contains
the sum of all wanted features.
ValueDescription
1 Disable the escape-character (. This is nor-
mally turned on during verbose output.
2 Add en empty line before the verbose text.
4 Add en empty line after the verbose text.
8 Print the verbose text with numbered lines.
This adds four digitsized spaces in the begin-
ning of each line. Finer control is available
with the string-variable Verbnm. It contains
all arguments to the troff-command .nm, nor-
mally ’1’.
16 Indent the verbose text with five ’n’:s. This
is controlled by the number-variable Verbin
(in units).

VERBOFF
End verbatim output.

VL text-indent [mark-indent [1]]
Variable-item list has no fixed mark, it assumes
that every LI have a mark instead. Text-indent
sets the indent to the text, and mark-indent the
distance from the current indent to the mark. A
third argument will prohibit printing of a blank
line before each item.

VM [top [bottom]]
Vertical margin.

WA [writer-name [title]]
Begins specification of the writer and writer’s
address. Several names can be specified with empty
WA/WE-pairs, but only one address.

WE Ends the address-specification after .WA.

WC [format]
Footnote and display width control.
N Set default mode, -WF, -FF, -WD and FB.
WF Wide footnotes, wide also in two-column mode.
-WF Normal footnote width, follow column mode.
FF All footnotes gets the same width as the first
footnote encountered.
-FF Normal footnotes, width follows WF and -WF.
WD Wide displays, wide also in two-column mode.
-WD Normal display width, follow column mode.
FB Floating displays generates a line break when
printed on the current page.
-FB Floating displays does not generate line
break.

INTERNALS
The letter macros is using different submacros depending
on the letter type. The name of the submacro has the let-
ter type as suffix. It is therefore possible to define
other letter types, either in the national macro-file, or
as local additions. .LT will set the number variables Pt
and Pi to 5 and 0. The following strings and macros must
be defined for a new letter type:

let@init_type
This macro is called directly by .LT. It is sup-
posed to initialize variables and other stuff.

let@head_type
This macro prints the letter head, and is called
instead of the normal page header. It is supposed
to remove the alias let@header, otherwise it will
be called for all pages.

let@sg_type name title n flag [arg1 [arg2 [...]]]
.SG is calling this macro only for letters, memo-
randums has its own processing. name and title is
specified thru .WA/.WB. n is the counter, 1-max,
and flag is true for the last name. Any other argu-
ment to .SG is appended.

let@fc_type closing
This macro is called by .FC, and has the formal
closing as argument.

.LO is implemented as a general option-macro. .LO demands
that a string named Lettype is defined, where type is the
letter type. .LO will then assign the argument to the
string variable let*lo-type.
