NAME

       mm, osdd - print documents formatted with the mm macros

SYNOPSIS

       [options] [files]

       [options] [files]

DESCRIPTION

       can  be	used  to format and print documents using and the text-formatting macro package (see nroff(1)).  It has options to specify prepro-
       cessing by and/or (see tbl(1) and neqn(1)), and postprocessing by various terminal-oriented output filters.  The proper pipelines  and  the
       required arguments and flags for and are generated, depending on the options selected.

       is equivalent to the command

   Options
       recognizes  the	following options and command-line arguments.  Any other arguments or options (such as are passed to or to as appropriate.
       Such options can occur in any order, but they must appear before the files arguments.  If no arguments are given,  prints  a  list  of  its
       options.

	      Specifies the type of output terminal;
		       for  a list of recognized values for term, type If this option is used, uses the value of the shell variable from the envi-
		       ronment (see profile(4) and environ(5)) as the value of term if is set; otherwise, uses as the value of term.   If  several
		       terminal types are specified, the last one is used.

	      Indicates that the document is to be produced in 12-pitch.
		       Can  be used when is set to one of and (The pitch switch on the DASI 300 and 300s terminals must be manually set to if this
		       option is used.)

	      Causes   to invoke col(1); note that col(1) is invoked automatically by unless term is one of and

	      Causes   to invoke

	      Causes   to invoke

DIAGNOSTICS

       sends the message if none of the arguments is a readable file and is not used as a filter.

EXAMPLES

       Assuming that the shell variable is set in the environment to the two command lines below are equivalent:

       reads the standard input when is specified instead of any file names (mentioning other files along with leads to  disaster).   This  option
       allows to be used as a filter, as in this example:

   Hints
       o  invokes with the option.  With this option, assumes that the terminal has tabs set every 8 character positions.

       o  Use the option of to specify ranges of pages to be output.  Note, however, that if invoked with one or more of the and options, together
	  with the option of may cause a harmless ``broken pipe'' diagnostic if the last page of the document is not specified in list.

       o  If you use the option of (to stop between pages of output), use line-feed (rather than return or new-line) to restart the  output.   The
	  option of does not work with the option of or if automatically invokes (see option above and col(1)).

       o  If you specify an incorrect output terminal type, produces (often subtle) unpredictable results.  However, if you are redirecting output
	  into a file, use the option, then use the appropriate terminal filter when actually printing the formatted file.
