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 preferred 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 possi-
      ble to localize the macros with companyname and so on.
 
      In this manual square brackets is used to show optional arguments.


      Number registers and strings
      Many  macros  can  be controlled by number registers and strings.  A number register is assigned with the nr com-
      mand:
      .nr XXX [+-]n [i]
      XXX is the name of the register, n is the value to be assigned, and i is increment value for  auto-increment.   n
      can  have  a  plus  or  minus sign as prefix if an increment or decrement of the current value is wanted.  (Auto-
      increment or decrement occurs if the number register is used with a plus or minus sign, \n+[XXX] 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  pre-
      fixed 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  foot-
             notes 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  con-
             tains 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 concatenated to one word, the
             first, third and so on will be printed in boldface.
 
      B1     Begin  box  (as the ms macro).  Draws a box around the text.  The text will be indented one character, and
             the right margin will be one character shorter.
 
      B2     End box.  Finish the box started by B1.
 
      BE     End bottom block, see BS.
 
      BI [bold-text [italic-text [bold-text [...]]]]
             Bold-italic.  No limit on the number of arguments, see B.
 
      BL [text-indent [1]]
             Start bullet list, initialize a list with a bullet and a space in the beginning of  each  list  item  (see
             LI).   Text-indent overrides the default indentation of the list items set by number register Pi.  A third
             argument will prohibit printing of a blank line before each item.
 
      BR [bold-text [roman-text [bold-text [...]]]]
             Bold-roman.  No limit on the number of arguments.
 
      BS     Bottom block start.  Begins the definition of a text block 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/groff/1.18.1/tmac/mm/arg.cov.  Therefore it is possible to cre-
             ate unlimited types of coversheets.  ms.cov is supposed to look like the ms coversheet.  .COVER requires a
             .COVEND at the end of the coverdefinition.  Always use this order of the 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 fol-
                  lowing 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 dis-
             play.  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  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 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 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), indenta-
             tion 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.  Footnotes in displays is now possible.  An empty line separates footnotes, the
             height of the line is controlled by number register Fs, default value is 1.
 
      GETHN refname [varname]
             Includes the headernumber where the corresponding SETR refname was placed.  Will be X.X.X. in pass 1.  See
             INITR.  If varname is used, GETHN sets the stringvariable varname to the headernumber.
 
      GETPN refname [varname]
             Includes  the  pagenumber  where  the corresponding SETR refname was placed.  Will be 9999 in pass 1.  See
             INITR.  If varname is used, GETPN sets the stringvariable varname to the pagenumber.
 
      GETR refname
             Combines GETHN and GETPN with the text 'chapter' and ', page'.  The string Qrf contains the text for  ref-
             erence:
                  .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 7, level 1 is the top level.
             The text is given in heading-text, and must be surrounded by double quotes if it contains  spaces.   Head-
             ing-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  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 number register Hi, default value 0.
 
             Hi
             0    The text will be left-justified.
             1    Indentation of the text will follow the value of number register Pt, see P.
             2    The text will be lined up with the first word of the heading.
 
             Centered section headings
             All headings whose level is equal or below number register Hc and also less than or equal to Hb or  Hs  is
             centerered.
 
             Font control of the heading
             The  font of each heading level is controlled by string HF.  It contains a fontnumber or fontname for each
             level.  Default is 2 2 2 2 2 2 2 (all headings in italic).  Could also be written as I I I I I I I.   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.  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
             Seven number registers, named H1 thru H7 contains the counter for each  heading  level.   The  values  are
             printed  using arabic numerals, this can be changed with the macro HM (see below).  All marks are concate-
             nated 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 con-
             tents.  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 following register is available for HX.  HX may
             alter }0, }2 and ;3.
             string }0
                  Contains the heading mark plus two spaces if rlevel is non-zero, otherwise empty.
             register ;0
                  Contains the position of the text after the heading.  0 means that the text should follow the heading
                  on  the  same  line,  1 means that a line break should occur before the text and 2 means that a blank
                  line should separate the heading and the text.
             string }2
                  Contains two spaces if register ;0 is 0.  It is used to separate the  heading  from  the  text.   The
                  string is empty if ;0 is non-zero.
             register ;3
                  Contains the needed space in units after the heading.  Default is 2v.
 
                  Can  be  used  to change things like numbering (}0), vertical spacing (}2) and the needed space after
                  the heading.
 
             HY dlevel rlevel heading-text
             HY is called after size and font calculations and might be used to change indentation.
 
             HZ dlevel rlevel heading-text
             HZ is called after the printing of the heading, just before H or HU exits.  Could be used  to  change  the
             page header according to the section heading.
 
      HC [hyphenation-character]
             Set  hyphenation  character.   Default  value  is  \%.   Resets to the default if called without argument.
             Hyphenation can be turned off by setting number register Hy to 0 in the beginning of the file.
 
      HM [arg1 [arg2 [... [arg7]]]]
             Heading mark style.  Controls the type of marking for printing of the heading counters.  Default is 1  for
             all levels.
 
             Argument
             1    Arabic numerals.
             0001 Arabic numerals with leading zeroes, one or more.
             A    Upper-case alphabetic
             a    Lower-case alphabetic
             I    Upper-case roman numerals
             i    lower-case roman numerals
             emptyArabic numerals.
 
      HU heading-text
             Unnumbered section header.  HU behavies like H at the level in number register Hu.  See H.
 
      HX dlevel rlevel heading-text
             Userdefined heading exit.  Called just before printing the header.  See H.
 
      HY dlevel rlevel heading-text
             Userdefined heading exit.  Called just before printing the header.  See H.
 
      HZ dlevel rlevel heading-text
             Userdefined heading exit.  Called just after 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 spec-
             ified 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 file-
             name.qrf.  Requires two passes with groff, this is handled by a separate program called mmroff, the reason
             is that groff is often installed without 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
             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 normally 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  cur-
             rent  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 reg-
             ister 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 controlled by number  regis-
             ter  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 column-size/15.  See also 1C.
 
      ML mark [text-indent [1]]
             Marked list start.  The mark argument will be printed before each list item.  Text-indent sets the  indent
             and overrides Li.  A third argument will prohibit printing of a blank line before each item.
 
      MT [arg [addressee]]
             Memorandum  type.  The arg is part of a filename in /usr/share/groff/1.18.1/tmac/mm/*.MT.  Memorandum 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 difference between  current
             and new pageoffset is used.  Use PGFORM without arguments to return to normal.
 
      MULB cw1 space1 [cw2 space2 [cw3 ...]]
             Begin  a  special  multi-column  mode.  Every columns width must be specified.  Also the space between the
             columns must be specified.  The last column does not need any space-definition.  MULB starts  a  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  nota-
             tions, see the string variable Letns and Letnsdef.
             Arg  Notation

      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 argument is 1, then the first line of text
             following P will be indented by the number of spaces in number register Pi, normally 5.
 
             Instead of giving 1 as argument to P it is possible to set the  paragraph  type  in  number  register  Pt.
             Using 0 and 1 will be the same as adding that value to P.  A value of 2 will indent all paragraphs, except
             after headings, lists and displays.
 
             The space between two paragraphs is controlled by number register Ps, and  is  1  by  default  (one  blank
             line).
 
      PGFORM [linelength [pagelength [pageoffset [1]]]]
             Sets  linelength,  pagelength and/or pageoffset.  This macro can be used for special formatting, like let-
             terheads 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 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 pic-
             ture.
 
      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 specified as "'left-part'cen-
             ter-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  diver-
             sion.   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 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 automati-
             cally.
 
             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 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 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 justi-
             fication, 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  pro-
             duce  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  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  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",  "TA-
             BLE", "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 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  environ-
             ment.  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-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 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.  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.

      Pgps   Controls  whether  header  and  footer pointsize should follow the current setting or just change when the
             header and footer is defined.
             ValueDescription
             0    Pointsize will only change to the current setting when .PH, .PF, .OH, .EH, .OF or .OE is executed.
             1    Pointsize will change after every .S.  This is the default.
 
      Ps     paragraph spacing, default 1.
 
      Pt     Paragraph type, default 0.
             0 == left-justified
             1 == indented .P
             2 == indented .P except after .H, .DE or .LE.
 
      Sectf  Flag controlling "section-figures".  A non-zero value enables this.  See also register N.
 
      Sectp  Flag controlling "section-page-numbers".  A non-zero value enables this.  See also register N.
 
      Si     Display indent, default 5.

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 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  speci-
             fied  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.
