It appears that some sites lost the part 5 of PROFF posting,
probably due to the size of the 5th part. It is my fault,
and I apologize for having to repost. The unformatted PROFF
manual is posted in 2 pieces:

X.sect 0 1.0 Introduction
X This manual describes PROFF, a formatter based on the FORMAT utility
Xpresented in
X.ul
XSoftware Tools.
X PROFF was produced to provide a powerful formatter that can be used under
Xa variety of microcomputers, thus providing a consistent formatting tool
Xacross environments. PROFF can be used to format memos, reports, form letters
Xand
Xdocuments such as this manual. It can also be configured to mimic
Xother formatting
Xsystems of similar nature.
X This document itself was produced with PROFF, using most of its advanced features.
XPROFF took care of such things as auto-paragraphing and the production of
Xthe Table of Contents as the manual was being formatted.
X PROFF was developed under a Digital Equipment Corporation Rainbow 100,
Xusing Mark Williams C Compiler for portability reasons. PROFF is
Xavailable under VAX/VMS operating system. PROFF implementations for
XIBM PC and APPLE ][ microcomputers are also underway.

X.sect 0 2.0 General Description
X.cl
X.sect 1 2.1 The Input
X The text that is to be formatted by PROFF is typed into an input file
Xusing any text editor. This file contains the text to be formatted
Xas well as PROFF commands.
X Each line in the input file is either a command line or a text line. A
Xcommand line is a line that begins with a period ("."). All other lines are
Xtext lines. The command lines are not printed - they tell PROFF how you want
Xit to format the text that follows. Appendix A summarizes all of the PROFF
Xcommands for a quick reference.
X.sect 2 2.1.1 Text
X Text can be entered into the input file in any format. PROFF removes all extra
Xblanks and tabs between words when operating in fill mode. This means you do
Xnot have to worry about how many words you put on a line, and you can break
Xlines wherever it is convenient to your typing. Note however, that you cannot
Xbreak a word between two lines.
X Blanks and tabs at the beginning of a line are not removed. This is useful
Xfor producing special tables and performing special types of indentation.
XThus, normal text lines should not have any leading tabs or blanks.
X.sect 2 2.1.2 Commands
X A command is a line that starts with a period. Immediately following the
Xperiod is a command name. Some commands accept a numeric quantity or a
Xcharacter string parameter, which must be separated from the command name
Xby a space or a comma. For example, an indent command might appear as follows:
X.save
X.in +5
X.nf
X.nj
X.sp
X|
X|It is to do nothing that the elect exists.
X|.in 5
X|- Oscar Wilde
X|
X.restore
X Assuming that the left margin was at column 1, PROFF would produce the
Xfollowing:
X.save
X.in +5
X.nf
X.nj
X.sp
X.need 4
X|
X|It is to do nothing that the elect exists.
X| - Oscar Wilde
X|
X.restore
X.sp
X(In the examples above, as in those following, the vertical line indicates
Xthe left edge of input or the left edge of the printed page).
X The number following the command may be preceeded by a "+" or "-" sign.
XThis plus or minus sign indicates an addition or subtraction of the number
Xto or from the current value for the command. for example, the text:
X.sp
X.save
X.in +5
X.nf
X.nj
X.need 11
X|
X|Nothing to do but work,
X|.in +3
X|Nothing to eat but food,
X|.in -3
X|Nothing to wear but clothes
X|.in +3
X|To keep one from going nude.
X|.in +7
X|-Benjamin King
X|
X.in -5
X.sp
Xwill produce as output:
X.sp
X.in +5
X.need 6
X|
X|Nothing to do but work,
X| Nothing to eat but food,
X|Nothing to wear but clothes
X| To keep one from going nude.
X| -Benjamin King
X|
X.restore
X If a number is not supplied with a command that requires a number, PROFF
Xwill use a default value. The defaults for each command are summarized in
XAppendix A.
X.cl
X.sect 1 2.2 The Output
X The main functions performed by PROFF are
X.ul
Xfilling
Xand
X.ul
Xjustifying.
XA line is
Xfilled by packing as many words onto it as will fit. The line is justified
Xby spacing words evenly between the left and right margins. When PROFF starts,
Xit assumes that the text is to be filled and justified. Of course, when fill
Xand justify are not needed (as in the case of a letter or a table), there are
Xcommands to turn these features off, and back on again, as necessary.
X When PROFF is in fill mode, it normally strips out extra spaces and tabs
Xbetween words.
X Many PROFF commands cause a
X.ul
Xbreak
Xto occur in the output. This means that the line currently being filled is
Ximmediately output. Any following text goes into a new output line.
X.cl
X.sect 1 2.3 Executing PROFF
X Once a text file is ready for formatting, PROFF is started by typing
Xthe program name, various options, name of the input file and the name
Xof the output file. For example the command
X.sp
X.in +5
XA> proff -po5 proffman.prf proff.man
X.sp
X.in -5
Xwould produce this document as proff.man, from an input file proffman.prf,
Xshifted right by 5 spaces.
X(The symbol "A>" is CP/M system prompt).
X.cl
X.sect 1 2.4 Bibliographic Notes
X PROFF wa produced by re-writing the Software Tools Formatter FORMAT.
XSome of the ideas are from Freshwater Institute RUNOFF, NROFF,
XUniversity of Waterloo SCRIPT
Xand other formatters of similar nature. The underlying ideas of the
Xmentioned above formatters may be found in
X.ul

X.sect 0 3.0 Command Descriptions
X This section describes PROFF commands. Commands specify how the program is
Xto process the text lines in the input file. Lines in the input file that
Xbegin with a period (or the control character selected by the user)
Ximmediately followed by a command name are commands. Any line that begins
Xwith a period and followed by a _# or _! is a comment line and is ignored
Xby PROFF - this allows you to put information in the file that will be neither
Xprocessed nor output by PROFF.
X As described earlier, some of the commands can be followed by "parameters".
XParameters are used in executing a command; for example, in the command
X".sp 3", the parameter "3" tells the formatter to insert 3 blank lines into
Xthe document. The following conventions are used in describing the parameters:
X.sp
X.in +5
X.ti -2
Xo Parameters surrounded by square brackets are optional. If not supplied, PROFF
Xassumes a default value.
X.br
X(e.g. .sp [n])
X.sp
X.ti -2
Xo Parameters surrounded by angle brackets are mandatory. PROFF will display
Xa fatal error message if the parameter is absent. (e.g. .set <variable name>)
X.sp
X.ti -2
Xo Parameters surrounded by squiggly brackets are to be typed exactly as
Xindicated. (e.g. .pn {roman})
X.sp
X.ti -2
Xo A bar character seperating the parameters within brackets indicate an
Xalternative. (e.g. .st [+|-][n] means both .st [+n] and .st [-n])
X.in -5
X In describing the commands, the command is typed exacty as accepted by PROFF
Xwith the associated control character default ("."). If more than one form of
Xthe command is accepted by PROFF, the command names are separated with a
Xbar indicating an alternative.

X\set FILL ".fi | .f | .fill"
X\comm FILL
XThe fill command causes a line to be filled with as many words as the right
Xmargin allows. For this purpose, all extra blanks and tabs are removed between
Xwords. Each word is separated with a single blank. PROFF automatically assumes
Xfill mode during the startup.
X\set NOFILL ".nf | .nofill"
X\comm NOFILL
XNo fill discontinues the filling of the text. PROFF simply copies the text
Xto the output. This command may be used to pass tables and other text
Xunaltered through the formatter.
X\set JUST ".ju | .j | .justify"
X\comm JUST
XJustify causes the words on a line to be evenly spaced between the left and
Xthe right margins. Note that lines can be justified only if lines are also
Xbeing filled. PROFF automatically assumes justify mode during the startup.
X\set NOJUST ".nj | .nojustify"

X\set BREAK ".br | .break"
X\comm BREAK
XBreak causes a break: the current line is printed without justification,
Xand the next word is placed at the beginning of a new line. Note that many
XPROFF commands cause an implicit break.
X\set INDENT ".in | .lm | .leftmargin [+|-][n]"
X\comm INDENT
XIndent causes a break and indents the following lines [n] spaces to the
Xright of the left margin. [n] can be negative to allow beginning a line
Xto the left of the left margin, however, a line cannot begin to the left of
Xcolumn 0. If a plus or minus sign is used with n, then [n] is added or
Xsubtracted to or from the current value.
X\set TINDENT ".ti | .i | .left [+|-][n]"
X\comm TINDENT
XTemporary indent is identical to the indent command except that it
Xapplies only to the next line of printed text. Thus, the command
X".ti +5" would cause the next line to be printed 5 spaces to the right
Xof those that follow.
X\set SPACETO ".st | .spaceto [-][n]"
X\comm SPACETO
XSpaceto allows spacing to line [n] from the top of the current page.
XIf a negative [n] is specified, than spacing is performed to line [n]
Xfrom the bottom of the page (excluding the footer lines). Thus, footnotes
Xcan be set at a fixed distance from the bottom of the page by a command such
Xas ".st -5".
X\set SPACE ".sp | .s | .skip [n]"
X\comm SPACE
XSpace causes a break and skips [n] lines, except at the top of
Xa page. The space command
Xis dependent on the setting of line spacing.
X\set CENTER ".ce | .center [n | on | off]"
X\comm CENTER
XCenter causes the next [n] lines of text to be centered between the left
Xand right margins. Centering may be started with "on" and terminated with
X"off", in which case all input lines between these commands will be centered.
X\set UNDLINE ".ul | .underline [n | on | off]"
X\comm UNDLINE
XUnderline command causes the text on the next [n] input lines to be underlined
Xwhen printed. If [n] is omitted, only the next line is underlined. This command
Xdoes not cause a break, so words in filled text may be underlined by:

XLine spacing is the command to set line spacing. Set n to 1 for single spacing,
X2 for double spacing etc.
X\set BP ".bp | .pg | .page [n]"
X\comm BP
XThe begin page command causes a break, ends the current page, outputs
Xfooters if required and begins a new page. If [n] is present, the page number
Xis set to [n]. The default action is to number the pages incrementally.
X\set PN ".pn | .pagenumber {roman} | {arabic}"
X\comm PN
XPage number command defines the format of the page number. Uppercase roman
Xnumerals may be obtained with "roman" keyword. To convert the page numbers
Xback to normal, "arabic" is specified. PROFF uses arabic numerals as
Xa default.
X\set NPA ".np | .nopaging"
X\comm NPA
XNo paging disables the pagination. When PROFF is in no paging mode,
X"begin page" (.bp) and "page length" (.pl) commands are ignored. This mode
Xof operation is especially useful for using the proff output with the
Xmulti-column formatter (MC).
X\set PA ".pa | .paging"
X\comm PA
XPaging enables normal page generation. This command starts a
Xnew page and restores the page length to the
Xvalue previous to the ".np" command.
X\set NE ".ne | .need | .tp | .testpage [n]"
X\comm NE
XTest page checks to see whether at least [n] lines remain in the
Xcurrent page. If less than this number of lines remain, printing will resume
Xat the top of a new page. If [n] is missing, it is assumed to be zero.
X\set HE ".he | .header <text>"
X\comm HE
XHeader sets the text to be printed on top of each page. <text> is
Xdivided into sections which are to be left justified, centered and right
Xjustified. To divide <text> into these three parts, the first character is
Xassumed to be a separator. (e.g. /left/center/right/) But any non-alphanumeric
Xcharacter may also be used. The characters "#" and "%" are replaced with the
Xcurrent page number and day/time in the header.

X.sect 1 3.5 Table of Contents
X This section describes the the commands that are used to generate a table of
Xcontents. Basically, a contents line command is used in every place in
Xthe document where an entry is needed in the table of contents. PROFF
Xstores the text and the page number when it encounters this command.
XAfter the the body of the document is processed, a print contents command
Xdumps the contents table. The contents should be dumped in a new page, with
Xnofill. Page numbering should be disabled if the table of contents is to be
Xused in front of the document.

Xin the table. When the table is printed, each level of entry will be
Xindented by specific number of spaces.
X<text> appears in the output exactly as it appears
Xin the contents line command, except that leading blanks are removed.
XIf no options specified in the contents line, a blank is inserted during
Xthe table output.
X\set PC ".pc | .printcont [n]"
X\comm PC
XPrint Contents causes the currently accumulated table of contents to be
Xprinted. If [n] is specified, it is used as the indent value for each
Xlevel. If [n] is not specified, it is defaulted to 3.
X A contents line at level 0 is as wide as rightmargin-indent. The
Xoutlook of the table of contents may be changed by altering the right
Xmargin and indent values. A typical table of contents may be produced as
Xfollows:

XSet variable defines a variable to be later used in the document.
XIf the definition part is left out, PROFF uses the variable name as a prompt
Xand allows the user to define the variable interactively. Variable names cannot
Xstart with a numeric character, and may only contain alphanumeric
Xcharacters. The definition of a variable may not contain any blanks, unless
Xthey are surrounded by double-quotes. To get a double quote within a a quoted
Xdefinition, two double-quotes are used.
X Once the variable is
Xdefined, it can be used anywhere in the document, including the command
Xline itself. A variable substitution is invoked by a dollar sign (_$). (A
Xliteral _$ is inserted into text using ___$).
XA variable name must be delimited by a non-alphanumeric character within the
Xtext. If the contents of the variable is to be appended to other
Xalphanumeric characters, it must be surrounded by wiggly braces
X("{" and "}"). The following is an example of variable usage:
X\need 12
X\sp
X\nf
X|.nf
X|.vs v1 Murphy
X|_${v1}'s first law:
X| Nothing is as easy as it looks.
X|_${v1}'s second law:
X| Everything takes longer than you think.
X|Charley's observation:
X| Computers were invented by _$v1.
X|
X\sp
XProduces the following:
X\sp
X\need 8
X|
X|Murphy's first law:
X| Nothing is as easy as it looks.
X|Murphy's second law:
X| Everything takes longer than you think.
X|Charley's observation:

X\set VGET ".vg | .get <variable> <prompt>"
X\comm VGET
XGet variable is the interactive version of variable definition. In this
Xvariant, a prompt string is used to obtain the value of the variable,
Xwhich is typed at the user's terminal. If the prompt string is to
Xcontain blanks, tabs etc., it must be enclosed in double quotes. No quotes
Xare necessary for input text.
X\set VRG ".nr <a-z> [+|-][n]"
X\comm VRG
XNumber register is used to define registers that contain numeric values.
XThere are 26 number registers, named a-z. The command ".nr x n" sets the
Xnumber register "x" to value n; ".nr x +n" increments the number register
Xby n; ".nr x -n" decrements the number register by n. The value of the
Xnumber register x is placed in the text by the appearance of _@nx. A literal
X_@ may be inserted using ___@.
XNumber registers may be used on command lines and anywhere in the text.
X\set CCHAR ".cc | .cchar [char]"
X\comm CCHAR
XControl Character sets the character that distinguishes PROFF
Xcommands from text to be formatted. As a default, control character is set to
X(".") period.
XThis character may be changed to something other than a period, either
Xto mimic other formatters or to disallow interpretation of lines beginning
Xwith a period. (This document makes heavy use of the .cc command).
X\set ECHAR ".ec | .echar [char]"
X\comm ECHAR
XEscape Character sets the character that disallows the
Xinterpretation of spacial characters such as _@ and _$. PROFF uses an
Xunderline ("__") character as a default.
X\set SOU ".so | .source | .include | .require [filename]"
X\comm SOU
XThe source (include) command allows external files to be inserted into the
Xinput file
Xduring the formatting. Using this feature, tables, graphs and other
Xdocuments generated outside PROFF may be included into the document
Xbeing formatted. This feature is also very useful in including a common set
Xof macros during formatting. Include files may be nested inside other
Xinclude files. Currently, PROFF only allows a nested include
Xfiles level of 8. Filename may be enclosed in quotes.
X\set SAVE ".sv | .save"
X\comm SAVE
XThe save command allows the saving of the current formatter context on a
Xpushdown stack. The saved context of the formatter segment (FSECT) includes
Xthe following values and flags:
X\need 14
X\sp
X\nf
X\nap
Xvalues flags on | off
X------ -----
Xindent (.in) fill (.fi | .nf)
Xright margin (.rm) justify (.ju | .nj)
Xoffset (.po) paging (.pa | .np)
Xline spacing (.ls) number type (.pn)
Xpage length (.pl) bolding (.eb | .db)
Xmargin values (.m1) autoparagraph (.ap | .na)
X (.m2)
X (.m3)
X (.m4)
Xcontrol char (.cc)
Xescape char (.ec)
X\sp
X\ap
X\fi
X\set RST ".rs | .restore"
X\comm RST
XThe restore command pops the context stack and restores the values and flags
Xas defined above.
X\set LEX ".lx | .lex <command> [equate]"
X\comm LEX
XThe lexical modification command is essentially a permanent replacement of a
Xgiven command. This command is used for changing the command names without
Xresorting to the macro facility. Lex permanently removes the old
Xcommand name from command tables and replaces it with the new definition.
XIf the equate is not specified, the command becomes undefined and is
Xno longer recognised by PROFF. The command equate should not contain
Xnon-alphanumeric characters.
X\set APR ".ap | .autoparagraph"
X\comm APR
XThe autoparagraph command turns on the automatic paragraphing feature. If
Xauto-paragraphing is on, every line that starts with a
X\ul
Xblank
Xor a
X\ul
Xtab
Xcharacter starts a new paragraph. A new line is generated (.sp) and
Xthe beginning of the paragraph is indented by five spaces.
XAutoparagraphing is the equivalent of the following commands:
X\in +5
X\nf
X|
X|textextextextext
X|.sp
X|.ti +5
X|textextextextext
X|
X\in -5
X\fi
X\set NAP ".na | nap | .noautoparagraph"
X\comm NAP
XNo Autoparagraph command disables auto-paragraphing.
X\set WRT ".wr | .write <string>"
X\comm WRT
XWrite is a special output command, only to be used to configure printers
Xand other output devices with escape sequences. This command outputs the
Xassociated string as it is encountered, without going through the normal
Xoutput routines of the formatter. Currently, the output string may contain
Xcontrol characters specified as "^<char>", decimal numbers within the range
Xof 1-255, and other characters. Blanks within the string are skipped. Any
Xportion of the string enclosed with double quotes is output as is. To output
Xa double quote, two double quotes must be used within the quoted string.
XFollowing is a typical string to set a Digital La-100 printer to letter
Xquality print mode:
X\sp
X\nf
X\in +5
X|
X|.wr ^["[2z"
X|
X\sp
X\fi
X\in -5
XIn the control string, "^[" is the ASCII equivalent of the Escape (esc) character.
XFollowing mapping table is used to convert characters starting with a caret
Xto their binary equivalents: ("|" indicates an alternative)
X\nf
X\nap
X\sp
X\in +5
XControl chr Dec. Oct. Hex.
