+.SH BASIC RUNOFF LANGUAGE OF ALL TIMES
+.\" --------------------------------------------------------------------
+.
+Files written in the
+.FONT CI RUNOFF
+language are similar to modern
+.FONT CI roff
+files.
+.
+.
+.P
+They are both written in text mode.
+.
+So they can be manipulated with text editors like
+.BR emacs (1).
+.
+.
+.P
+In files written in the text languages
+.FONT CI RUNOFF
+or
+.FONT CI roff R ,
+there are command lines and text lines.
+.
+.
+.\" --------------------------------------------------------------------
+.SS Basic Command Lines
+.\" --------------------------------------------------------------------
+.
+All lines beginning with a period (dot)
+.FONT CB .
+are command lines in both languages
+.FONT CI RUNOFF
+and
+.FONT CI roff R .
+.
+The period is followed by the name of the command (1 or 2 words of
+arbitrary length, later one even more words), optionally followed by 1
+or more arguments.
+.
+.
+.P
+The inventor
+.FONT CI Saltzer
+called the command name
+.IR "control word" ,
+but we keep using
+.I command name
+as was done in later times.
+.
+.
+.P
+In
+.FONT CI roff R ,
+lines starting with a single quote
+.FONT CB '
+are also command lines, but that's not true for the
+.FONT CI RUNOFF
+language by default.
+.
+.
+.P
+But in
+.FONT CI RUNOFF R ,
+the period
+.FONT CB .
+at the beginning of a line can be changed into any character.
+.
+This can be done by the command
+.FONT CB ".FLAG CONTROL" R .
+.
+So the starting period is only one possible special character.
+.
+But in this man\-page, we use the period before a command name,
+because it is the default and helps recognizing commands directly.
+.
+.
+.P
+In
+.FONT CI RUNOFF R ,
+the command names were quite long, sometimes consisting even of
+several words.
+.
+This is the same in the
+.FONT CI mom
+language in
+.FONT CI groff R .
+.
+.
+.P
+Moreover, the
+.FONT CI RUNOFF
+commands can be appreviated by defined 2 letters words (or 3 later on).
+.
+Later on, the
+.FONT CI "classical roff"
+languages used only the 2-letter abbreviations as requests; but
+.FONT CI groff
+expanded these to arbitrary length.
+.
+.
+.P
+In
+.FONT CI RUNOFF R ,
+each
+.FONT CI "control word"
+(command name) can be written in upper or lower case.
+.
+That comes from the time where the computers had only upper case input.
+.
+This was not taken into
+.FONT CI roff R ,
+because there were not enough 2-letter requests.
+.
+.
+.P
+In
+.FONT CI RUNOFF R ,
+comments could be appended to a command line, see section
+.FONT CB Comments R .
+.
+.
+.P
+Lines beginning with a period but having unrecognizable format are
+treated as error.
+.
+.
+.P
+No lines beginning with a dot are printed unless the preceding line
+was a
+.I command line
+with control name
+.FONT CB .LITERAL R .
+.
+Then the the line is output or printed as is, special characters are
+output without their special meaning.
+.
+.
+.P
+Abbreviations for command names are normally based on the first two
+letters of a one word command or the first letter of the first two
+words of a multi\-word command.
+.
+Later on 3-letter abbreviations where used for command names of 3
+words.
+.
+.
+.P
+An example of a
+.I "control line"
+(command line) with a single
+.I "control word"
+with 2 arguments is a long name with upper case
+.IP
+.FONT CB .COMMAND I " arg1 arg2"
+.P
+or the same name in lower case
+.IP
+.FONT CB .command I " arg1 arg2"
+.P
+or an abbreviation with upper case
+.IP
+.FONT CB .CO I " arg1 arg2"
+.P
+or the same abbreviation with lower case
+.IP
+.FONT CB .co I " arg1 arg2"
+.
+.
+.P
+Another example of a
+.I "control line"
+(command line) with 2
+.I "control words"
+with 1 argument is a long name with upper case
+.IP
+.FONT CB ".WORD1 WORD2" I " arg"
+.P
+or the same name in lower case
+.IP
+.FONT CB ".word1 word2" I " arg"
+.P
+or an abbreviation with upper case
+.IP
+.FONT CB .WW I " arg"
+.P
+or the same abbreviation in lower case
+.IP
+.FONT CB .ww I " arg"
+.
+.
+.P
+These
+.I "control words"
+were renamed to
+.I requests
+and
+.I macros
+later on in
+.FONT CI roff R .
+.
+.
+In the 1973 document, the words
+.I macros
+and
+.I formats
+are used, but there isn't any documentation for these terms.
+.
+.
+.\" --------------------------------------------------------------------
+.SS Comments
+.\" --------------------------------------------------------------------
+.
+In
+.FONT CI roff R ,
+comments can be included by preceding the special character combination
+.FONT CB \[rs]\[rq] R .
+.
+.
+.P
+That was unknown in
+.FONT CI RUNOFF R .
+.
+There was only 1 method for including comments.
+.
+Command lines could be appended by comments.
+.
+.
+.P
+In the original
+.FONT CI RUNOFF
+language, a comment could be appended after the command arguments
+without using separators.
+.
+For example,
+.RS
+.word1 word2 arg1 arg2 This is a comment
+.RE
+.
+.
+.P
+In the newer
+.FONT CI RUNOFF
+languages (documented in 1974), they preceded the comments in command
+lines by the exclamation point (bang)
+.FONT CB ! R .
+.
+For example,
+.RS
+.word1 word2 arg1 arg2 !This is a comment
+.RE
+.
+.
+.\" --------------------------------------------------------------------
+.SS Basic Text Lines
+.\" --------------------------------------------------------------------
+.
+All lines that are not command lines are text lines in both languages.
+.
+.
+.P
+There are 2 modes of text lines in
+.FONT CI RUNOFF R .
+.
+The newer mode had upper and lower case in the source file.
+.
+This was similar to
+.FONT CI roff R .
+.
+.
+.P
+In the
+.FONT CI CTSS
+computer (early 1960s), there were only upper case input hardware.
+.
+So the
+.FONT CI RUNOFF
+files had only upper case ASCII characters in the original
+.FONT CI RUNOFF
+language.
+.
+.
+.P
+As the printers could print in upper and lower case, there were
+special characters as case-shifters.
+.
+That was also used in late
+.FONT CI RUNOFF
+files.
+.
+This process is very different from
+.FONT CI roff R .
+.
+.
+.P
+In the following sections, only the upper case text lines are documented.
+.
+.
+,P
+In
+.FONT CI RUNOFF
+and
+.FONT CI roff R ,
+there are special character combinations that can change the handling
+of the text.
+.
+But these special characters are totally different in both languages.
+.
+.
+.P
+One or more
+.I blank lines
+are not printed, but mean a
+.IR "line break" .
+.
+This can also be reached by the
+.FONT CB .BREAK
+.IR "control word" .
+.
+.
+.P
+In
+.IR groff ,
+blank lines are printed as lines of their own.
+.
+This is not a paragraph break, because a line is bigger than a
+paragraph break.
+.
+.
+.P
+A text line that starts with one or more space characters means
+.IR "begin a new paragraph" .
+.
+.
+.P
+In
+.IR groff ,
+this will start a new line and inserts the space characters at the
+beginning of the line.
+.
+.
+.\" --------------------------------------------------------------------
+.SS Appending several Lines in RUNOFF
+.\" --------------------------------------------------------------------
+.
+In 1974, it is documented that several text or command lines can be
+appended into a single line starting with a command.
+.
+.
+.P
+These lines should be separated by a
+.FONT CI semi\-colon CB ; R .
+.
+If the appended line is a command line, then it starts with a period.
+.
+That's enough for separation.
+.
+In this case, separating semi\-colon can be omitted.
+.
+.
+.\" --------------------------------------------------------------------
+.SS Default Conditions (modes) in RUNOFF
+.\" --------------------------------------------------------------------
+.
+The starting case-mode (for output or printing) is lower case.
+.
+Each text line starts with that mode.
+.
+.
+.P
+Usually the text is
+.I filled
+and
+.I justified
+as it is processed.
+.
+That is, the program
+.I fills
+a line by adding successive words from the source text until one more
+word would cause the right margin to be exceeded.
+.
+The line is then
+.I justified
+by making the word spacings larger until the last word in the line
+exactly meets the right margin.
+.
+.
+.P
+The user may occasionally wish to reproduce the source text exactly,
+which is done by disabling
+.I filling
+and
+.I justification
+or by use of the
+.FONT CR .LITERAL
+command.
+.
+The program may be set to
+.I fill
+but not
+.IR justify ,
+in which case the output will be normal except that lines will not be
+justified to the right margin.
+.
+The program may also be set to
+.I justify
+but not
+.IR fill ,
+although this would probably produce peculiar results and is not
+recommended.
+.
+.
+.P
+When the
+.I fill mode
+is on, spaces and carriage returns occurring in the source text are
+treated only as word separators.
+.
+Multiple separators are ignored.
+.
+.
+.P
+Some of the commands cause a BREAK in the output.
+.
+A
+.I break
+means that the current line is output without justification, and the
+next word goes at the beginning of the next line.
+.
+This occurs at the end of paragraphs.
+.
+.
+.P
+The program will advance to new pages as necessary, placing the title
+(if given) and the page number at the top of each page.
+.
+The user may call explicitly for a
+.I page advance
+where desired, and may inhibit the occurrence of a
+.I page advance
+within specified material.
+.
+.
+.P
+By the documentation of 1974 and 1981, some special characters in text
+lines are initially disabled:
+.FONT CB < R " (" CB CAPITALIZE R ),
+.FONT CB > R " (" CB INDEX R ),
+.FONT CB = R " (" CB HYPHENATE R ),
+and
+.FONT CB % R " (" CB OVERSTRIKE R ).
+.
+.
+.P
+The other special characters seem to be enabled by default.
+.
+These should be:
+.FONT CB . R " (" CB CONTROL R ),
+.FONT CB ! R " (" CB ENDFOOTNOTE R ),
+.FONT CB ^ R " (" CB UPPERCASE R ),
+.FONT CB \[rs] R " (" CB LOWERCASE R ),
+.FONT CB & R " (" CB UNDERLINE R ),
+.FONT CB # R " (" CB SPACE R ),
+and
+.FONT CB _ R " (" CB QUOTE R ).
+.
+.
+.P
+This can be changed by the commands

+.
+Also, each special character can be set to another character by the

+.
+In this section, the specification of case for files prepared on an

+.SS Margin Controls
+.\" --------------------------------------------------------------------
+.
+There are two types of margins involved in
+.FONT CI RUNOFF R .
+.
+.
+.TP
+(1)
+The physical margins.
+.
+These are determined by the nature of the printing device.
+.
+The margins outline the area where it is physically possible to print
+characters.
+.
+.
+.TP
+(2)
+.
+The logical margins.
+.
+These can be set bv the user as he wishes.
+.
+(Limits are imposed by the physical margins.)
+.
+They are initialized for standard 8.5\[dq] by 11\[dq] printing.
+.
+.
+.P
+Commands concerning vertical and horizontal margins are:
+.
+.
+.TP
+.FONT CB ".PAGE LAYOUT TM, EM, TOL"
+This sets the vertical logical margins and vertical tolerence.
+.
+Parameters are top margin, bottom margin and tolerance.
+.
+The tolerance is used to determine where to break between pages on
+page overflows.
+.
+If
+there is a line break within
+.I TCL lines
+of the bottom,
+.FONT CB RUNOFF
+will break the page there; otherwise it will fill the page completely.
+.
+.
+.TP
+.FONT CB ".LINE LAYOUT LM, RM, NO, CS"
+This sets the logical left and right margin, the number of columns,
+and the number of spaces to insert between columns.
+.
+These margins are used for the page headings.
+.
+To adjust the relative
+text position, use the subsequent commands.
+.
+.
+.TP
+.FONT CB ".REDUCE MARGIN LM, RM"
+.TQ
+.FONT CB ".EXPAND MARGIN LM, RM"
+.TQ
+.FONT CB ".END REDUCTION"
+These commands enable the user to indent a certain portion of his text
+using the first command, or
+.FONT CB .UNDENT
+his text using the second command.
+.
+In either case the original margins are restored by the third command.
+.
+The use of several
+.FONT CB ".REDUCE MARGIN"
+commends before the corresponding
+.FONT CB ".END REDUCTION"
+commands succesively indents the text more, and more.
+.
+Thus these commands are 1ike brackets (i.e. recursive).
+.
+.FONT CB LM
+is added to the left logical margin and
+.FONT CB RM
+is subtracted from the right logical margin in the first command.
+.
+Just
+the opposite is done on the second command.
+.
+Negative numbers are permitted.
+.
+These commands do not effect the position of page headings.
+.
+.
+.TP
+.FONT CB ".LAYOUT PLM, PRM, PTM, PBM, LL, LO"
+This command defines the physical margins in the followinq complex
+manner.
+.
+(It should only be used for non\-standard devices, normally this
+command should not be necessary.)
+.
+The parameters are the physical left margin (in spaces), the physical
+right margin, the physical top 1ine, the physical bottom line, the
+line lenqth, and line origin.
+.
+The first four parameters define the physical 1imits of the printing
+device.
+.
+The final two parameters define the length of the logical line and its
+origin with respect to the left edge of the paper.
+.
+Printing starts at column
+.FONT CB "LO + LM" R ,
+and ends at
+.FONT CB "LO + RM" R ,
+where
+.FONT CB LM
+and
+.FONT CB RM
+are the logical margins established by
+.FONT CB ".LINE LAYOUT" R .
+.
+When using the
+.FONT CI "facing feature"
+(see
+.FONT CB ".PAGING MODE" R ),
+the logical left margin is
+.FONT CB "LL \[em] RM"

+.SS Further Study of Experimental Additions
+.\" --------------------------------------------------------------------
+.
+A number of suggestions have been made for extending the
+.I control word
+language of
+.FONT CI RUNOFF R ,
+and its capabilities.
+.
+These are listed here, primarily to elicit comment and discussion,
+both on the language which describes these operations and the less
+important problem of their implementation.
+-
+.
+.TP
+1.
+.
+Word division.
+.
+This is a whole are of study in itself.
+.
+.
+.TP
+2.
+.
+Automatic footnote insertion.
+.
+This was handled somewhat awkwardly in the
+.FONT CB .DITTO
+.IR command ,
+although the basic approach was probably reasonable.
+.
+.
+.TP
+3.
+.
+Automatic page references, perhaps via some symbolic reference scheme.
+.
+This would enable the page number in "as was described on page 32" to
+be inserted by the program.
+.
+The analogy with an assembly program should be hotly pursued for
+ideas.
+.
+.
+.TP
+4.
+.
+Special provision for printing facing pages.
+.
+This would require alternate running heads, placing page numbers
+alternately at right and left, and matching line counts on facing
+pages.
+.
+.
+.TP
+5.
+.
+Improved page\-division rules, to prevent the last line of a paragraph
+appearing alone at the top of a page, for example.
+.
+At present, copy must be run off to check by hand that awkward page
+divisions have not been made.
+.
+.
+.TP
+6.
+.
+Automatic generation of page numbers for a table of contents.
+.
+Again, the analogy of an assembly program symbol table appears
+fruitful.
+.
+.
+.TP
+7.
+.
+Automatic generations of an index.
+.
+The problem here is obtaining too many references to a given word,
+many irrelevant.
+.
+.
+.TP
+8.
+.
+Arrangement of tabulated data.
+.
+This problem may have already been partly approached with the
+above\-described figure generator, or the facilities already available
+in
+.IR RUNOFF ,
+but automatic setup of column widths and positions would be desirable.
+.
+One could include in this category the ability to call on other
+programs to computer numbers to place in tables, although this is
+going pretty far afield.
+.
+.
+.TP
+9.
+.
+Placing figures in a
+.I "cut"
+or
+.IR inset .
+.
+The control language is the most difficult problem here.
+.
+.
+.TP
+10.
+.
+Equation typing and numbering.
+.
+Again, the control language appears formidable.
