;THIS MACRO IS USED TO FORCE A PAGE OVERFLOW WITH COMMENT
;TO HAVE LISTINGS MATCH THE PROPOSED CODING STANDARD.
;
;IT IS INVOKED WHENEVER A PAGE OVERFLOW WOULD HAVE HAPPENED.
;
;
;ACCORDING TO THE PROPOSED STANDARD, ALL SOURCE FOR A ROUTINE
;MUST OCCUR ON ONE PAGE. HOWEVER, IT IS IMPORTANT FOR THE
;USER TO FIND "SENTENCE" BREAKS TO FORM THE OVERFLOW (EJECT)
;POINTS. WHENEVER OVERFLOW OCCURS, A COMMENT
;TO THAT EFFECT SHOULD APPEAR IN THE LISTING. ALL THIS IS
;ACCOMPLISHED BY THE USER INCLUDING THE MACRO "CONT." IN HIS
;SOURCE AT THE POINT OF THE OVERFLOW. NO BLANKS SHOULD PRECEED
;OR FOLLOW THE MACRO.

;RUNOFF starts the translation by inserting a comment which
;identifies the version of RUNOFF, the date it was run, the
;name of the file being processed and its creation date and
;time. Text is processed by copying each character to the
;output. Case control commands are processed, so the output
;file is in upper and lower case as appropriate to the
;requested format. Horizontal spacing commands (explicit and
;implicit) are converted into the comparable TYPESET
;commands. In particular, RUNOFF breaks the input into lines
;just as if it were doing the final copy itself. Underlining
;is converted to italics. The double space after a period,
;etc., is dropped unless the final output is /TYPESET:LPT.
;When the various commands and internal flags are
;encountered, if RUNOFF can not complete processing itself,
;it generates the appropriate TYPESET-10 command. If there
;is no perfect command, then RUNOFF generates a macro to
;TYPESET-10. If the macro corresponds to a RUNOFF command,
;then the macro name is the same as the standard RUNOFF
;command abbreviation (e.g., [*TP] for any test page whether
;a user command or an implicit one).
;
;Commands which relate to horizontal spacing are treated as
;follows. The comparable commands are issued to TYPESET-10
;but the spacing is modified in order to achieve a
;typesetting width of 36 unless /TYPESET:LPT is selected (in
;which case, the RUNOFF spacing is kept). The conversion to
;width 36 is achieved by multiplying the input number by
;36/page width as set in the last PAPER SIZE or STANDARD
;command. The result is issued as picas and points.
;
;Commands relating to pagination are converted to TYPESET-10
;macros and are ignored. Similarly, the output does not
;include sequence numbers, change bars, or variable flagging.
;Since the paging will be chosen by the final editor,
;footnotes are dumped as soon as possible. In particular,
;they are output at the next break surrounded by horizontal
;lines to help break them up.
;RUNOFF produces the following macros when translating to
;TYPESET-10. They are generally issued right in line without
;any free line feeds.
;.LM16.P-16,,6.AUTOTABLE

COMMENT \
;.NOSELECT
.P; ?RNFCJL CAN'T JUSTIFY LINE
.SK1; The string of input between spaces (and end of line)
is greater than the separation between left and
right margins and therefore does not fit in the
output even before any attempt to expand spaces.
.P; ?RNFDVN DUPLICATE VARIABLE NAME: ".command"
.SK1; This variable command is attempting to declare a
variable which has already been declared. This
declaration will be ignored.
.P; ?RNFEFD END FOOTNOTE DOESN'T FOLLOW FOOTNOTE: ".command"
.SK1; This end footnote command appears at a place in the
file which is not immediately following a footnote
command and the corresponding footnote data.
.P; ?RNFELD END LITERAL DOESN'T FOLLOW LITERAL: ".command"
.SK1; This end literal command appears at a place in the
file which is not immediately following a literal
command and the corresponding literal text. It
probably reflects that the count on the literal
command is incorrect.
.P; ?RNFEVL EXCEEDING VARIABLE LIST: ".command"
.SK1; Only a maximum of 20 variables can be declared.
This command is attempting to declare the 21-st
variable. This and all further variable
declarations will be ignored, although the message
will not be repeated.
.P; ?RNFFIF FOOTNOTE INSIDE FOOTNOTE: ".command"
.SK1; This command is attempting to start a footnote
definition only it occurs within a footnote
definition, which is illegal. It probably indicates
that the previous footnote definition was never
terminated.
.P; ?RNFIBO INPUT BUFFER OVERFLOW
.SK1; A string of characters has been input which is so
long between spaces (or the right margin is so
large) that it has overflowed the internal line
buffer storage area.
.P; ?RNFIFT ILLEGAL IN FOOTNOTE: ".command"
.SK1; This command is illegal within a footnote.
.P; %RNFIIF ^x IGNORED IN INPUT FILE
.SK1; Control characters are not normally allowed in the
input file. This character was input and is being
ignored. If it should be input, then declare
".CONTROL CHARACTERS" in order to make it legal.
.P; ?RNFILC ILLEGAL COMMAND: ".command"
.SK1; This command is illegal for some reason. Most
reasons are that a key word was not recognized or
that an argument was out of range.
.P; %RNFJEC JUNK AT END OF COMMAND: ".command"
.SK1; The command, after all its arguments, still has some
other characters which are not blanks or comments.
.P; [RNFKCF nK CORE - FOOTNOTE]
.SK1; Core was expanded because of growth in the footnote
storage area. If this repeats indefinitely it
probably indicates that the footnote was improperly
terminated.
.P; [RNFKCI nK CORE - INDEX]
.SK1; Core was expanded because of growth in the index
storage area. In a well indexed document this
message should be output occasionally as processing
progresses.
.P; ?RNFLDE LITERAL DOESN'T END WITH .END LITERAL: ".command"
.SK1; After a counted literal, the next line is not an end
literal command. This probably indicates that the
count is wrong.
.P; ?RNFNEC NOT ENOUGH CORE nK
.SK1; Core has been expanded to the limit of what the
monitor is allowed to assign to this job. The
processing is aborted at this point.
.P; ?RNFNFS NO FILE SPECIFIED
.SK1; The user has specified some switches or an output
file, but has not specified an input file.
.P; %RNFNIA NEGATIVE INDENT ATTEMPTED
.SK1; The sum of the indent and the left margin is less
than zero, meaning that the line should start to the
left of the left edge of the paper. Either the left
margin has been misset or the indent is wrong. The
indent might be implicit in a paragraph or table
request. This message is output only once until the
next left margin or SD command.
.P; %RNFNIC ANOTHER n NEGATIVE INDENTS COUNTED
.SK1; This message indicates how many additional negative
indents were discovered since the last NIA message.
.P; ?RNFNID NO INPUT DEVICE
.SK1; The user has failed to specify either an input
device or file.
.P; ?RNFODE OUTPUT ERROR xxxxxx
.SK1; The output file has an I/O error whose octal code is
included in the message.
.P; %RNFSPO SUBPAGE OVERFLOW
.SK1; While incrementing the subpage counter, it got
larger than 26. This probably indicates that the
end subpage command is missing.
.P; %RNFTFE TOO FEW END COMMANDS
.SK1; When the end of the input was reached there were not
the same number of end (or end list or end note)
commands as there had been list and note commands.
This probably indicates that an end command is
missing.
.P; ?RNFTMI INSUFFICIENT CORE FOR COMMAND
.SK1; The user has specified so many input file
specifications that RUNOFF could not fit them into
core. The command should be split into several
commands.
.P; ?RNFTMR TOO MANY RANGES
.SK1; The user has specified too many IRANGE or ORANGE
pairs to fit in the storage space assigned (20 pairs
each). Fewer ranges should be specified.
.P; ?RNFTMV TOO MANY /VARIANTS
.SK1; The user has specified too many VARIANTS in the
command. Only 20 variants can be specified in one
command.
.P; %RNFTNN TOO MANY NESTED NOTES
.SK1; More than 6 nested notes and lists has occured.
This probably indicates that one or more end
commands is missing.
.P; ?RNFUKV UNKNOWN VARIABLE: ".command"
.SK1; On an if, ifnot, else, or endif command a variable
was referenced which was not declared in a variable
command. This usually indicates a spelling error or
a missing variable command.
.P; %RNFUME UNMATCHED END COMMAND
.SK1; More end commands have occured than list or note
commands.
.P; ?RNFVVZ /VARIANT VALUE ZERO
.SK1; In a VARIANT switch, the value was null or zero.
Variants always have names.
