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 follow-
       ing limitations:

       o      no Bell Labs localisms implemented.

       o      the macros OK and PM are not implemented.

       o      groff mm does not support cut marks

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

       A file called locale or lang_locale is read after the initiation 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 command:
       .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 decre-
       ment 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] or \n-[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 for-
       mat 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:

       )E level text
	      Adds  text  (heading-text)  to the table of contents with level either 0 or between
	      1-7.  See also .H.  This macro is used for customized table of contents.

       1C [1] Begin one column processing.  An 1 as argument disables 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 beginning 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 correct pagenumber.  The name
	      APPENDIX can be changed by setting the string App to the desired text.  The  string
	      Apptxt contains the current appendix 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 on 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 the cover sheet (MT 4 only).
	      2    Abstract  will be printed only on the cover sheet (other than MT 4 only).  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 signature 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 not appear before TL.  The
	      author information can contain initials, location, department, telephone extension,
	      room number or name and up to three extra arguments.

       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.

       AVL [name]
	      Letter signature, generates a line with place for signature.

       B [bold-text [prev-font-text [bold...]]]
	      Begin  boldface.	 No limit on the number of arguments.  All arguments will be con-
	      catenated 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 which is printed at  the
	      bottom of each page.  Block ends with BE.

       BVL text-indent [mark-indent [1]]
	      Start  of  broken variable-item list.  Broken variable-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 important that .COVER appears before
	      any normal text.	.COVER uses arg to build the filename /usr/share/tmac/mm/arg.cov.
	      Therefore  it is possible to create unlimited types of coversheets.  ms.cov is sup-
	      posed to look like the ms coversheet.  .COVER requires a .COVEND at the end of  the
	      coverdefinition.	Always use this order of the covermacros:
	      .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 controlled 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 section (when section-page numbering
		   is active) or at the end of the document.
	      1    A new display will be printed on the current page if 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 [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 second argument prevents the empty line between each list  item  to  be  printed.
	      See LI.  A third argument will prohibit printing of a blank line before each item.

       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 (reasonably :-).

	      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 prevent 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 format  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 List of Equations will only be printed if  number  register  Le  is  1,
	      default  0.  The string Liec contains the word Equation, wich is printed before the
	      number.  If refname is used, then the equation number is saved with .SETR, and  can
	      be retrieved with .GETST refname.
	      Special handling of the title will occur if EC is used inside DS/DE, it will not be
	      affected by the format of DS.

       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.

       EPIC [-L] width height [name]
	      EPIC draws a box with the given width and height, it will also print the text  name
	      or  a  default  string if name is not specified..  This is used to include external
	      pictures, just give the size of the picture.  -L will leftadjust the  picture,  the
	      default is to center adjust.  See PIC

       EQ [label]
	      Equation	start.	 EQ/EN	are  the delimiters for equations 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 margin.

       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 List of Exhibits will only be printed if number register Lx is 1,
	      default  1.  The string Liex contains the word Exhibit, which is printed before the
	      number.  If refname is used, then the exhibit number is saved with .SETR,  and  can
	      be retrieved with .GETST refname.
	      Special handling of the title will occur if EX is used inside DS/DE, it will not be
	      affected by the format of DS.

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

       FD [arg [1]]
	      Footnote	default format.  Controls the hyphenation (hyphen), right margin justifi-
	      cation (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 mm is 10.

       FE     Footnote end.

       FG [title [override [flag [refname]]]]
	      Figure  title, arguments are the same as for EC.	FG uses the number register Fg as
	      counter.	The string Lf controls the title of the List of Figures, default is  LIST
	      OF  FIGURES.   The List of Figures will only be printed if number register Lf is 1,
	      default 1.  The string Lifg contains the word Figure, wich is  printed  before  the
	      number.  If refname is used, then the figure number is saved with .SETR, and can be
	      retrieved with .GETST refname.
	      Special handling of the title will occur if FG is used inside DS/DE, it will not be
	      affected by the format of DS.

       FS [label]
	      Footnote	start.	The footnote is ended by FE.  Footnotes is normally automatically
	      numbered, the number 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.  Foot-
	      notes 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 var-
	      name to the pagenumber.

       GETR refname
	      Combines GETHN and GETPN with the text 'chapter' and ', page'.  The string Qrf con-
	      tains 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 varname 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 14, level
	      1 is the top level.  The text is given in heading-text, and must be  surrounded  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 indentation.

	      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 heading level is less or equal to num-
	      ber 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 controlled 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 fontnum-
	      ber or fontname for each level.  Default is 2 2 2 2 2 2 2 2 2 2 2 2 2 2 (all  head-
	      ings  in italic).  Could also be written as I I I I I I I I I I I I I I.	Note that
	      some other implementations use 3 3 2 2 2 2 2 as the  default  value.   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 0 0 0 0 0 0 0.  Beware that only the point size changes, not the ver-
	      tical size.  That can be controlled by the user specified macro HX and/or HZ.

	      Heading counters
	      Fourteen number registers, named H1 thru H14 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 are concatenated before printing.  To avoid  this,
	      set  number  register Ht to 1.  That will only print the current 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).  Argument rlevel is the real level, it is set to num-
	      ber register Hu for unnumbered headings.	Argument heading-text is the  text  argu-
	      ment to H and HU.

	      HX level rlevel heading-text
	      HX  is  called  just before the printing of the heading.	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 head-
		   ing 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  indenta-
	      tion.

	      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 off by setting number register Hy to 0
	      in the beginning of the file.

       HM [arg1 [arg2 [... [arg14]]]]
	      Heading mark style.  Controls the type of marking for printing of the heading coun-
	      ters.  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 printing the header.  See H.

       I [italic-text [prev-font-text [italic-text [...]]]]
	      Italic.  Changes the font to italic if called without arguments.	With one argument
	      it will set the word in italic.  With two argument it will concatenate 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.

       INITI type filename [macro]
	      Initialize  the  new index system, sets the filename to collect index lines in with
	      IND.  Argument type selects the type of index, page number, header marks	or  both.
	      The default is N.

	      It  is also possible to create a macro that is responsible for formatting each row.
	      Add the name of the macro as argument 3.	The macro will be called with  the  index
	      as argument(s).

	      type
	      N    Page numbers
	      H    Header marks
	      B    Both page numbers and header marks, tab separated

       INITR filename
	      Initialize the refencemacros.  References will be written to stderr and is supposed
	      to be written to filename.qrf.  Requires two passes with groff, this is handled  by
	      a separate program called mmroff, the reason is that groff is often installed with-
	      out the unsafe operations that INITR requiered.  The first pass  looks  for  refer-
	      ences and the second one includes them.  INITR can be used several times, but it is
	      only the first occurrence of INITR that is active.

	      See also SETR, GETPN and GETHN.

       IND arg1 [arg2 [...]]
	      IND writes a line in the index file selected by INITI with all  arguments  and  the
	      page number or header mark separated by tabs.
		   Examples
		   arg1\tpage number
		   arg1\targ2\tpage number
		   arg1\theader mark
		   arg1\tpage number\theader mark

       INDP   INDP  prints  the index by running the command specified by string variable Indcmd,
	      normally sort -t\t.  INDP reads the output from the command to form the index, nor-
	      mally in two columns (can be changed by defining TYIND).	The index is printed with
	      string variable Index as	header,  default  is  INDEX.   One-column  processing  is
	      returned	after  the list.  INDP will call the user-defined macros TXIND, TYIND and
	      TZIND if defined.  TXIND is called before printing INDEX, TYIND is  called  instead
	      of  printing  INDEX.   TZIND  is	called after the printing and should take care of
	      restoring to normal operation again.

       ISODATE [0]
	      ISODATE changes the predefined date string in  DT  to  ISO-format,  ie  YYYY-MM-DD.
	      This  can  also be done by adding -rIso=1 on the command line.  Reverts to old date
	      format if argument is 0.

       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  nor-
	      mally 0.	The mark area ends where the text begins.  The start of the text is still
	      controlled 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 LI 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.  There will be no separating space between the prefix and  the  mark  if  the
	      second  argument is 2 instead of 1.  This behaviour can also be achieved by setting
	      number register Limsp to zero.  A zero length  mark  will  make  a  hanging  indent
	      instead.

	      A  blank line is normally printed before the list item.  This behaviour can be con-
	      trolled 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 begin 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 margin.
	      SP   Simplified.	Almost the same as  the  full-blocked  style.	Subject  and  the
		   writer's identification are 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 CONFIDENTIAL on the second line below the date
		   line.  Any argument replaces CONFIDENTIAL.  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 col-
	      umn-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/tmac/mm/*.MT.  Memo-
	      randum type 0 thru 5 are supported, including  "string".	 Addressee  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 dif-
	      ference 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 diversion 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.  See .P.

       NCOL   Force  printing  to  the next column, don't use this together with the MUL* macros,
	      see 2C.

       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 argument 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 standard 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 normal footer.  See EF and PF.

       OH [arg]
	      Odd-page header, a line printed just below the normal 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 produce left justified text, even the
	      first  line of the paragraph.  This is the same as setting type to 0.  If the argu-
	      ment 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.   (It seems as if this macro sometimes doesn't work too well.  Use the
	      command line arguments to change linelength,  pagelength	and  pageoffset  instead.
	      Sorry.)

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

       PIC [-L] [-C] [-R] [-I n] filename [width [height]]
	      PIC  includes  a	Postscript file in the document.  The macro depends on mmroff and
	      INITR.  -L, -C, -R and -I n adjusts the picture  or  indents  it.   The  optionally
	      width and height can also be given to resize the picture.

       PE     Picture end.  Ends a picture for pic, see the manual 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 speci-
	      fied  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 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 are 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 automati-
	      cally incremented number between square brackets.  Text-indent changes the  default
	      indentation.

       RP [arg1 [arg2]]
	      Produce  reference page.	RP can be used if a reference 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 reset if arg1 is 1.

	      Arg2 tells RP whether to eject a page or not.
	      Arg2
	      0    The reference page will be printed on a separate 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 suppress 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 definition.   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 regis-
	      ter  :R.	If string-name is given, a string with that name will be defined and con-
	      tain the current reference mark.	The string can be referenced  as  \*[string-name]
	      later in the text.

       S [size [spacing]]
	      Set point size and vertical spacing.  If any argument is equal 'P', then the previ-
	      ous value is used.  A 'C' means current value, and 'D' default value.   If  '+'  or
	      '-' is used before the value, then increment or decrement of the current value will
	      be done.

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

       SETR refname [string]
	      Remember	the current header and page-number as refname.	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 if the second argument is given, otherwise at
	      the last.  No reference data will be printed if the  author(s)  is  specified  thru
	      .WA/.WE.	See 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,  concatenated  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 produce the maximum number of lines, not the sum.  SP will also be
	      ignored until the first textline in a page.  Add a \& 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, arguments are the same as for EC.  TB uses the number register  Tb  as
	      counter.	 The  string Lt controls the title of the List of Tables, default is LIST
	      OF TABLES.  The List of Tables will only be printed if number  register  Lt  is  1,
	      default  1.   The  string  Litb contains the word TABLE, wich is printed before the
	      number.
	      Special handling of the title will occur if TB is used inside DS/DE, it will not be
	      affected by the format of DS.

       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 controls 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, centered, before the table of contents.

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

	      Equivalent  macros  can  be  defined  for  list  of  figures, tables, equations and
	      excibits by defining TXxx or TYxx, where xx is Fg, TB, EC or EX.

	      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
	      contain  "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 are saved for use in the front  page  process-
	      ing.

       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 separate environment.	Linelength is preserved though.

       TS [H] Table start.  This is the start of a table specification to tbl.	See separate man-
	      ual  for	tbl.   TS ends with TE.  Argument H tells mm 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 second argument.
	      By specifying the font-argument it is possible  to  use  another	font  instead  of
	      courier.	 flag  controls  several  special  features.   It contains the sum of all
	      wanted features.
	      ValueDescription
	      1    Disable the escape-character (\).  This is normally turned on  during  verbose
		   output.
	      2    Add an empty line before the verbose text.
	      4    Add an empty line after the verbose text.
	      8    Print  the verbose text with numbered lines.  This adds four digitsized spaces
		   in the beginning of each line.  Finer control is available  with  the  string-
		   variable Verbnm.  It contains all arguments to the troff-command .nm, normally
		   '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 cur-
	      rent  indent  to the mark.  A third argument will prohibit printing of a blank line
	      before each item.

       VM [-T] [top [bottom]]
	      Vertical margin. Adds extra vertical top and margin space.  Option -T set the total
	      space  instead.  No argument resets the margin to zero or the default (7v 5v) if -T
	      was used. It is higly recommended that macro TP and/or EOP are defined if using  -T
	      and setting top and/or bottom margin to less than the default.

       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 letter type as suffix.  It is therefore possible to define other let-
       ter  types,  either  in	the national macro-file, or as local additions.  .LT will set the
       number variables Pt and Pi to 0 and 5.  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 supposed 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, memorandums  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 argument 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.
