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:

       +      no Bell Labs localisms implemented.

       +      the macros OK and PM are not implemented.

       +      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 pre-
       ferred language.  Use mmse as an example.

       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  num-
       ber 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 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] 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 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:

       )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 over-
              printed.

       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 appen-
              dix 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 argu-
              ments  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 over-
              rides 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 possi-
              ble  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.  For-
              mat, 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  sec-
                   tion-page  numbering  is active) or at the end of the docu-
                   ment.
              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 col-
                   umn (in multi-column mode).
              3    Print  one  display if there is enough space for it, other-
                   wise it will be printed at the top of the next page or col-
                   umn.
              4    Print  as many displays that will fit in a new page or col-
                   umn.  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 compat-
              ibility 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 num-
              ber 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 EQUATIONS.  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 num-
              ber.  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 speci-
              fied..  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 mem-
              orandum.  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

              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 nor-
              mally 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.   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 headernum-
              ber.

       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 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 head-
              ing-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 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 controlled by  num-
              ber 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  head-
                   ing.

              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 fontname for each level.  Default is
              2 2 2 2 2 2 2 2 2 2 2 2 2 2 (all  headings  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 vertical  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 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 heading.  The  fol-
              lowing  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
              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 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  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  bold-
              face.  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 references 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, normally in two columns  (can  be
              changed  by  defining  TYIND).  The index is printed with string
              variable Index as header, default is INDEX.  One-column process-
              ing 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 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 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 be-
              haviour  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
                   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 CONFIDEN-
                   TIAL.  See also string variable LetCN.
              RN   Reference notation.  Prints In reference to: and the  argu-
                   ment  two lines below the date line.  See also string vari-
                   able 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 let-
                   ter 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 cre-
              ate 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/tmac/mm/*.MT.   Memorandum  type  0  thru  5 are sup-
              ported, 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 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  speci-
              fied.  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 argu-
              ment is available, then the argument becomes  the  entire  nota-
              tion.   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.

       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  jus-
              tified  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 spa-
              ces 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 regis-
              ter 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  neces-
              sary.   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 pageheader 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  specifica-
              tion.

       PH [arg]
              Page  header, a line printed at the top of each page.  The argu-
              ment  should  be  specified  as   "'left-part'center-part'right-
              part'", where left-, center- and right-part is printed left-jus-
              tified, 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  bold-
              face.  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.  Diver-
              sion and/or prompt can be empty ("").

       RF     Reference  end.  Ends a reference definition and returns to nor-
              mal 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 automatically 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 register :R.  If
              string-name is given, a string with that name  will  be  defined
              and  contain the current reference mark.  The string can be ref-
              erenced as \*[string-name] later in the text.

       S [size [spacing]]
              Set point size and vertical spacing.  If any argument  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 increment 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  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 specifed 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 num-
              ber 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 spac-
              ing 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  arguments.   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  head-
              ing-level.   It must be scaled, like .ds Ci .25i .5i .75i 1i 1i.
              The indentation is normally controlled by the maxlength of head-
              ings 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 lan-
              guages.

       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 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
              separate environment.  Linelength is preserved though.

       TS [H] Table start.  This is the start of a table specification to tbl.
              See separate manual 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-argu-
              ment  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  con-
                   trolled 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 [-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.   Sev-
              eral 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 letter 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 ini-
              tialize 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 argu-
              ment.

       .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.
