Apple Lisa XENIX Text Processing - Tenox.tc

6.1 Introduction
N rofl' and troff are the XENIX text processing formatting programs. N rofl' can
be used to output text to terminals, lineprinters, and letter-quality printers.
Trofl' can be used to output text to a number or phototypesetters and laser
printers. Both programs use identical commands, which are interspersed with
lines or text. The· commands used by both programs allow you to control the
style or headers and footers, footnotes, paragraphs, and sections. You may
specify font and point size, spacing, multiple column output, and local motions
to create overstriking and line drawing effects.
Because nrofl' and trofl' are highly compatible with each other, it is almost
always possible to prepare input acceptable to both. By using conditional
input, you may add commands which are specific to either program.
6.1.1 Invoking nrofl' and trofl'
The general form of invoking the formatters on the command line is:
or
nroff options files
troff options files
where optione represents any or a number or option arguments and file
represents a list or files containing the document to be formatted. An argument
consisting or a single minus sign (-) is taken to be a filename corresponding to
the standard input. Ir no filenames are given, input is taken from the standard
input. The options may appear in any order so long as they appear before the
filenames. They are:
-olist Prints only pages whose page numbers appear in liet, which consists
of comma-separated numbers and number ranges. A number range
has the Corm N-M and means pages N through M; an initial -N
means from the beginning to page N, and a final N- means from N
to the end.
-nN Numbers first generated page N.
-sN Stops every N pa.ges. Nrofl'will halt prior to every N pages(default
N = 1) to allow paper loading or changing, and resume upon receipt
or a newline. Trofl' will stop the phototypesetter every N pages,
produce a trailer to allow changing cassettes, and will resume after
the phototypesetter "start" button is pressed.
-m name Prepends the macro file / uer/lib/tmac. name to the input files.
