MM(1)                                                       MM(1)

          mm - print out documents formatted with the MM macros

          mm [ options ] [ files ]

          Mm can be used to type out documents using nroff(1) and the
          MM text-formatting macro package.  It has options to specify
          preprocessing by tbl(1) and/or neqn(1) and postprocessing by
          various terminal-oriented output filters.  The proper pipe-
          lines and the required arguments and flags for nroff(1) and
          MM are generated, depending on the options selected.

          Options for mm are given below.  Any other arguments or
          flags (e.g., -rC3) are passed to nroff(1) or to MM, as
          appropriate.  Such options can occur in any order, but they
          must appear before the files arguments.  If no arguments are
          given, mm prints a list of its options.

          -Tterm   Specifies the type of output terminal; for a list
                   of recognized values for term, type help term2.  If
                   this option is not used, mm will use the value of
                   the shell variable $TERM from the environment (see
                   profile(5) and environ(7)) as the value of term, if
                   $TERM is set; otherwise, mm will use 450 as the
                   value of term. If several terminal types are speci-
                   fied, the last one takes precedence.
          -12      Indicates that the document is to be produced in
                   12-pitch.  May be used when $TERM is set to one of
                   300, 300s, 450, and 1620.  (The pitch switch on the
                   DASI 300 and 300s terminals must be manually set to
                   12 if this option is used.)
          -c       Causes mm to invoke col(1); note that col(1) is
                   invoked automatically by mm unless term is one of
                   300, 300s, 450, 37, 4000A, 382, 4014, tek, 1620,
                   and X.
          -e       Causes mm to invoke neqn(1); also causes neqn to
                   read the /usr/pub/eqnchar file (see eqnchar(7)).
          -t       Causes mm to invoke tbl(1).
          -E       Invokes the -e option of nroff(1).
          -y       Causes mm to use the non-compacted version of the
                   macros (see mm(7)).

          As an example (assuming that the shell variable $TERM is set
          in the environment to 450), the two command lines below are

               mm -t -rC3 -12 ghh*
               tbl ghh* | nroff -cm -T450-12 -h -rC3

     MM(1)                                                       MM(1)

          Mm reads the standard input when - is specified instead of
          any file names.  (Mentioning other files together with -
          leads to disaster.)  This option allows mm to be used as a
          filter, e.g.:

               cat dws | mm -

          1.   Mm invokes nroff(1) with the -h flag.  With this flag,
               nroff(1) assumes that the terminal has tabs set every 8
               character positions.
          2.   Use the -olist option of nroff(1) to specify ranges of
               pages to be output.  Note, however, that mm, if invoked
               with one or more of the -e, -t, and - options, together
               with the -olist option of nroff(1) may cause a harmless
               ``broken pipe'' diagnostic if the last page of the doc-
               ument is not specified in list.
          3.   If you use the -s option of nroff(1) (to stop between
               pages of output), use line-feed (rather than return or
               new-line) to restart the output.  The -s option of
               nroff(1) does not work with the -c option of mm, or if
               mm automatically invokes col(1) (see -c option above).
          4.   If you lie to mm about the kind of terminal its output
               will be printed on, you'll get (often subtle) garbage;
               however, if you are redirecting output into a file, use
               the -T37 option, and then use the appropriate terminal
               filter when you actually print that file.
