^^NOTICE: T\\HIS MEMORANDUM DESCRIBES A PROGRAM WHICH
^DIGITAL ^EQUIPMENT ^CORPORATION HAS NO COMMITTMENT
TO OFFER OR SUPPORT AT THIS TIME. ^THIS MEMORANDUM
IS, HOWEVER, BELIEVED TO BE AN ACCURATE 
DESCRIPTION OF ^^RUNOFF\\.
.CHAPTER INTRODUCTION
.ID -5
.HEADERLEVEL 1 <INTRODUCTION
^^RUNOFF\\ IS A ^^PDP\\-11 PROGRAM RUNNING UNDER ^^RSX\\ 
TO FACILITATE THE
PREPARATION OF TYPED OR PRINTED MANUSCRIPTS, SUCH AS MEMOS,
MANUALS, ETC.  ^THE USER PREPARES HIS MATERIAL ON ANY
REGULAR ^^PDP\\-11 TERMINAL, AND WRITES IT ONTO A FILE USING
^^EDIT11\\.  ^THE USER INCLUDES NOT ONLY
TEXTUAL MATERIAL, BUT ALSO CASE AND FORMATTING INFORMATION.
^^RUNOFF\\ THEN TAKES THE FILE AND REPRODUCES IT ONTO THE
LINE PRINTER, TELETYPE OR OTHER FILE TO PRODUCE A FINAL COPY
OR FINAL FILE IMAGE.  ^IT PERFORMS THE FORMATTING AND
CASE SHIFTING AS DIRECTED, AND WILL ALSO PERFORM LINE
JUSTIFICATION, PAGE NUMBERING AND TITLING, ETC.,
AS DESIRED.
.SKIP
^THE PRINCIPAL BENEFIT OF SUCH A PROGRAM IS THAT FILES
PREPARED FOR USE WITH IT MAY BE EDITED AND CORRECTED EASILY.
^SMALL OR LARGE AMOUNTS OF MATERIAL MAY BE ADDED OR DELETED, AND
UNCHANGED MATERIAL NEED NOT BE RETYPED.
^AFTER A SET OF CHANGES, THE PROGRAM MAY BE OPERATED TO
PRODUCE A NEW COPY WHICH IS PROPERLY PAGED AND FORMATTED.
^DOCUMENTATION MAY THUS BE UPDATED AS NECESSARY WITHOUT
REQUIRING EXTENSIVE RETYPING.

^^RUNOFF\\ IS A PROGRAM MUCH LIKE MOST ^^PDP-11\\
^^RSX\\ SYSTEM PROGRAMS. ^IT IS ACCESSED BY THE USUAL "^^MCR\\" COMMAND
"^^MCR>RNO#---#\\"

.SKIP
^AS STATED ABOVE, THE SOURCE FILE CONTAINS THE TEXTUAL MATERIAL
WHICH WILL APPEAR ON THE FINAL COPY, PLUS INFORMATION TO
SPECIFY FORMATTING.  ^MOST IMPORTANTLY, UPPER AND LOWER CASE
INFORMATION MAY ALSO BE SUPPLIED SO THAT COPY CAN BE PREPARED ON
THE TELETYPE OR OTHER SUCH DEVICE WHICH CAN NORMALLY INPUT ONLY
UPPER CASE LETTERS.  ^ALL COMMAND INFORMATION CONSISTS
OF REGULAR ^^ASCII\\ PRINTING CHARACTERS SO THAT A LISTING OF
THE SOURCE FILE MAY BE EXAMINED IF THE FINAL COPY IS NOT
EXACTLY AS DESIRED.
.SKIP
^ALL MATERIAL IN THE SOURCE FILE IS TAKEN TO BE SOURCE TEXT
EXCEPT THOSE LINES BEGINNING WITH A PERIOD.  ^A LINE BEGINNING
WITH A PERIOD IS ASSUMED TO BE A COMMAND,
.INDEX ^COMMAND FORMAT
 AND MUST MATCH ONE
OF THOSE LISTED BELOW.  ^THE COMMANDS PROVIDE THE FORMATTING
INFORMATION, AND CONTROL VARIOUS OPTIONAL MODES OF OPERATION.
.SKIP
^USUALLY THE TEXT IS FILLED
.INDEX ^FILLING OF TEXT
 AND JUSTIFIED
.INDEX ^JUSTIFICATION OF TEXT
 AS IT IS PROCESSED.
^THAT IS, THE PROGRAM ^^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 ^^JUSTIFIED\\ BY
MAKING THE WORD SPACINGS LARGER UNTIL THE LAST WORD IN THE LINE
EXACTLY MEETS THE RIGHT MARGIN.
.SKIP
^THE USER MAY OCCASIONALLY WISH TO REPRODUCE THE SOURCE TEXT
EXACTLY, WHICH IS DONE BY
DISABLING ^^FILLING\\ AND ^^JUSTIFICATION.  T\\HE PROGRAM MAY BE SET
TO ^^FILL\\ BUT NOT ^^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 ^^JUSTIFY\\ BUT NOT ^^FILL\\, 
ALTHOUGH THIS WOULD PROBABLY PRODUCE PECULIAR RESULTS AND
IS NOT RECOMMENDED.

 AND CARRIAGE RETURNS 
OCCURRING IN THE SOURCE TEXT ARE TREATED ONLY AS WORD
SEPARATORS.  ^MULTIPLE SEPARATORS ARE IGNORED.
.SKIP
^SOME OF THE COMMANDS CAUSE A ^^BREAK\\
.INDEX ^BREAK
 IN THE
OUTPUT.  ^A ^^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.

DESIRED, AND MAY INHIBIT THE OCCURRANCE OF A PAGE ADVANCE
WITHIN SPECIFIED MATERIAL.

.HEADERLEVEL 1 ^^CASE INFORMATION\\
.INDEX ^^CASE INFORMATION\\
^SPECIFICATION OF CASE FOR FILES PREPARED ON THE TELETYPE IS
DONE WITH TWO CHARACTERS, UP-ARROW
(_^, SHIFT-^N), AND BACK-SLASH (_\, SHIFT-^L).
^THE APPEARANCE OF AN UP-ARROW CAUSES THE LETTER IMMEDIATELY
FOLLOWING TO BE TRANSMITTED IN UPPER CASE.  ^THE APPEARANCE
OF A BACK-SLASH CAUSES THE LETTER IMMEDIATELY FOLLOWING TO
BE CONVERTED TO LOWER CASE.  ^ANY LETTER NOT PRECEEDED BY ONE OF
THESE CHARACTERS IS TRANSMITTED IN THE CURRENT MODE.  ^THE MODE
IS INITIALLY LOWER CASE, AND IS CHANGED BY THE OCCURRANCE
OF TWO SUCCESSIVE CASE CONTROL CHARACTERS.  ^TWO 
UP-ARROWS (_^_^) CAUSE THE MODE TO BE SET TO UPPER CASE,
AND TWO BACK-SLASHES (_\_\) CAUSE THE MODE TO BE SET TO
LOWER CASE.
.SKIP
^THE USE OF THE ABOVE CORRESPONDS TO THE USE OF THE SHIFT AND
SHIFT-LOCK KEYS ON A TYPEWRITER.  ^USUALLY, TYPING APPEARS
IN LOWER CASE. ^TO TYPE ONE LETTER IN UPPER CASE, THE SHIFT
KEY IS USED.  ^THE SHIFT-LOCK IS SET TO TYPE A SERIES OF
UPPER CASE LETTERS, AFTER WHICH IT IS RELEASED.
.SKIP
.X ^LESS-THAN
^IN ADDITION, THE LESS-THAN (_<) CHARACTER CAUSES SUBSEQUENT CONVERSION
TO UPPER CASE UNTIL A WORD TERMINATOR (SPACE, QUOTED SPACE, <CR OR <TAB)
CHARACTER OCCURS, EFFECTIVLY CAPITALIZING THE FOLLOWING WORD.
.SKIP
^THE FOLLOWING SHOWS THE USES OF THE CASE CONTROL CHARACTERS:
.SKIP 1
^^_<HERE IS A _^SAMPLE _^SENTENCE IN _^_^UPPER CASE_\_\ AND
LOWER CASE.
\\
.SKIP 1
BECOMES:
.SKIP 1
<HERE IS A ^SAMPLE ^SENTENCE IN ^^UPPER CASE\\ AND LOWER CASE.
.SKIP
^NOTE: ^CASE CONVERSION TAKES PLACE ONLY ON ^^ASCII\\
CODES 101 TO 132 OCTAL, THAT IS, THE UPPER CASE LETTERS.  ^ANY
ACTUAL LOWER CASE LETTERS (CODES 141 TO 172 OCTAL) APPEARING
IN THE SOURCE WILL BE TRANSMITTED UNCHANGED.  ^IF THE SOURCE
IS PREPARED ON A DEVICE SUCH AS A FLEXOWRITER
OR MODEL 37 TELETYPE WHICH PRODUCES
LETTERS OF THE PROPER CASE, THE MODE SHOULD BE SET TO
UPPER CASE AT THE BEGINNING OF THE FILE AND LEFT UNCHANGED FOR
THE REMAINDER.

.HEADERLEVEL 1 ^^SPECIAL CHARACTERS\\
.INDEX ^^SPECIAL CHARACTERS\\
^THE CHARACTER AMPERSAND (_&, SHIFT-6) IS USED TO SPECIFY
UNDERSCORING.
.INDEX ^UNDERSCORING
^THE AMPERSAND WILL CAUSE THE CHARACTER FOLLOWING IT TO BE
UNDERSCORED, E.G. _&F_&O_&O BECOMES ^&FOO\&.
.SKIP
^UNDERLINING OF A STRING OF CHARACTERS CAN ALSO BE SPECIFIED,
SIMILAR TO THE USE OF THE SHIFT LOCK OPERATIONS DESCRIBED ABOVE.
 ^AN
APPEARANCE OF AMPERSAND PRECEDED BY UP-ARROW (_^_&) WILL
CAUSE UNDERLINING OF ALL FOLLOWING CHARACTERS EXCEPT SPACE. ^AN
APPEARANCE OF AMPERSAND PRECEDED BY BACKSLASH (_\_&) WILL
DISABLE THIS MODE.
.SKIP
^THE PRESENT VERSION OF ^^RUNOFF\\ USES THE ^^ASCII\\ CHARACTER
137 FOR AN UNDERLINE.
^THIS CHARACTER MAY BE CHANGED BY A REASSEMBLY OF ^^RUNOFF\\
IF NECESSARY.
.SKIP
.INDEX ^SPACE
.INDEX ^QUOTED ^SPACE
^IT IS OCCASIONALLY NECESSARY TO INCLUDE SPACES IN THE TEXT
WHICH SHOULD NOT BE TREATED AS WORD SEPARATORS. ^FOR
THIS PURPOSE, ^^RUNOFF\\ TREATS ^&NUMBERSIGN\& (_#) AS A
QUOTED SPACE; I.E. IT WILL PRINT AS EXACTLY ONE SPACE IN THE
OUTPUT, WILL NEVER BE EXPANDED NOR CHANGED TO A CARRIAGE RETURN.
.SKIP
^TO ALLOW THE APPEARANCE OF THE SPECIAL CHARACTERS (AMPERSAND,
NUMBER-SIGN, UP-ARROW, LESS-THAN, OR BACK-SLASH) IN
THE OUTPUT, THE CHARACTER LEFT-ARROW (__, SHIFT-^O) IS USED
AS A QUOTE 
.INDEX ^QUOTE CHARACTER
CHARACTER.  ^THE CHARACTER IMMEDIATELY FOLLOWING
A LEFT-ARROW WILL BE TRANSMITTED TO THE OUTPUT WITH NO
FORMATTING EFFECT.
^THE LEFT ARROW ITSELF IS THUS ANOTHER CASE REQUIRING
QUOTING. ^THE FOLLOWING SIX CASES OCCUR: ___&,
___^, ___<,  ___\, ____, AND ___#.

.INDEX ^COMMAND FORMAT
.SKIP
^THE FOLLOWING COMMANDS WILL BE RECOGNIZED IF THEY ARE AT THE
BEGINNING OF A LINE STARTED WITH A PERIOD.  ^MOST COMMANDS
HAVE AN ABBREVIATED FORM HERIN SPECIFIED BY "[^X^X]". ^ANY LINE IN THE
SOURCE FILE BEGINNING WITH A PERIOD IS ASSUMED TO BE ONE OF
THESE COMMANDS.  ^IF IT IS NOT, AN ERROR DIAGNOSTIC WILL BE
TYPED AND THE LINE WILL BE IGNORED.  ^SOME COMMANDS TAKE 
A TEXT OR NUMERIC ARGUMENT(S) FOLLOWING THE COMMAND. IN THIS CASE
THE ARGUMENT MUST BE SEPERATED FROM THE COMMAND BY A '<SPACE'.
.PARAGRAPH 0
^ANY COMAND OF THE FORM <'.;#XXXXXXX' WILL DEFAULT TO A "^^COMMENT\\"
COMMAND. ^IT WILL HAVE NO EFFECT ON RUNOFF AND WILL NOT BE OUTPUT. ^ITS SOUL
PURPOSE IS TO ENABLE ENTRY OF COMMENT LINES INTO THE SOURCE TEXT.
.X ^COMMENT
.X ;
.PP 0
^MULTIPLE COMMANDS CAN BE CONCATENATED ON ONE LINE. ^FOLLOWING TWO
<RUNOFF STANDARDS THEY MAY BE SEPERATED BY A ";" (.XXXX;.YYYY) OR
MAY JUST BE SUCCESSIVLY TYPED (.XXXX.YYYY). NOTE THAT DUE TO THIS, A "<COMMENT"
COMMAND CAN NOT CONTAIN A PERIOD, INASMUCH AS THIS LOOKS LIKE A NEW COMMAND.
^ALSO COMMANDS SUCH AS <PARAGRAPH, <CENTER, ETC WHICH ARE EXPECTING A LINE
OF OUTPUT TEXT DIRECTLY FOLLOWING MUST BE THE LAST COMMAND IN THE LINE.
