03700 ^^SOS\\ VERSION 23(220) IS THE ^^DEC\\-DISTRIBUTED
03800 VERSION 21(122) WITH ALL KNOWN BUGS FIXED AND MANY USEFUL IMPROVEMENTS.
03900 ^THIS VERSION INCORPORATES FIXES TO ALL PROBLEMS REPORTED IN OUTSTANDING
04000 ^^SPR\\S, ALL FIXES MADE IN THE CURRENT ^^DEC\\ IN-HOUSE VERSION OF
04100 ^^SOS\\, AND OTHER FIXES DEVELOPED BY THE ^UNIVERSITY OF ^ILLINOIS, THE
04200 ^NATIONAL ^INSTITUTES OF ^HEALTH, AND ^BROOKINGS.
04300 ^IMPROVEMENTS WERE MADE TO PROVIDE ADDITIONAL FEATURES AS REQUESTED
04400 BY VARIOUS ^^SOS\\ USERS, TO MAKE ^^SOS\\ MORE EASIER TO USE AND MORE
04500 EFFICIENT TO RUN, AND TO INCORPORATE USEFUL FUNCTIONS FROM OTHER
04600 VERSIONS OF ^^SOS\\.
04700 ^ALL IMPROVEMENTS WERE CAREFULLY DESIGNED TO BE CONSISTENT WITH THE
04800 ^^SOS\\'S DESIGN PHILOSOPHY AND TO PROVIDE THE MAXIMUM BENEFIT FROM
04900 THE MINIMUM AMOUNT OF CORE.
05000 ^THIS VERSION HAS BEEN TESTED ON ^^KA\\ AND ^^KI\\ ^^DEC\\SYSTEM-10'S,

06800 2.4 ^THE ^ALTER COMMAND ("^A") HAS BEEN IMPROVED IN A
06900 NUMBER OF USEFUL WAYS:
07000
07100 .LEFT MARGIN 12
07200 .TAB STOPS 12
07300 .BLANK 1
07400 .INDENT -6
07500 2.4.1 ^IN ^ALTER MODE, THE COMMAND "_^^R" TYPES
07600 OUT THE CURRENT LINE FROM THE LEFT MARGIN TO THE CURRENT POSITION.
07700 ^THIS TYPE-OUT CLOSELY APPROXIMATES THE NORMAL _^^R OUTPUT.
07800 ^NOTE THAT _^^R MAY BE TYPED ANYTIME IN ^ALTER MODE, EVEN WHILE
07900 INSERTING TEXT INTO A LINE WITH THE ^ALTER-MODE "^I" OR "^R"
08000 COMMANDS, OR WHILE TYPING ARGUMENTS TO THE ^ALTER-MODE
08100 "^C", "^S", OR "^K" COMMANDS.
08200
08300 .BLANK 1
08400 .INDENT -6
08500 2.4.2 ^SIMILARLY, THE COMMAND "_^^U" WILL ALWAYS BE TAKEN IN
08600 ^ALTER MODE TO RESTART THE CURRENT LINE, EVEN FOLLOWING
08700 A "^I", "^R", "^C", "^S", OR "^K" OPERATION.
08800 .BLANK 1
08900 ^NOTE THAT "_^^U" WILL PRODUCE AN UNEXPECTED EFFECT WHEN TYPED
09000 IN AS TEXT FOR THE ^EXTEND ("^X") COMMAND.
09100 ^BECAUSE THE "^X" COMMAND IS IMPLEMENTED AS AN ^ALTER MODE
09200 OPERATION WITH AN AUTOMATIC INSERTION AT END OF LINE, TYPING
09300 "_^^U" TERMINATES THE INSERTION AND THEN PUTS YOU IN ^ALTER
09400 MODE AT THE BEGINNING OF THE LINE.
09500
09600 .BLANK 1
09700 .INDENT -6
09800 2.4.3 ^THE ^BACKSPACE CHARACTER (_^^H) IS NOW COMPLETELY EQUIVALENT
09900 TO THE ^RUBOUT CHARACTER (ALSO KNOWN AS THE ^DELETE OR ^DEL CHARACTER,
10000 177 OCTAL, SOMETIMES WRITTEN AS "_<^^RO\\_>") IN ^ALTER MODE.
10100 ^THIS MEANS THAT ^BACKSPACE, LIKE ^RUBOUT, DELETES THE PREVIOUS
10200 CHARACTER AS AN "^I" OR "^R" COMMAND CHARACTER, TERMINATES THE
10300 "^C", "^S", OR "^K" COMMAND OPERATION, OR AS AN ^ALTER
10400 COMMAND BACKS UP THE CURRENT CHARACTER POSITION.
10500
10600 .BLANK 1
10700 .INDENT -6
10800 2.4.4 ^THE ^ALTER-MODE COMMANDS "_^", "_<", AND "_>" HAVE
10900 BEEN IMPLEMENTED.
11000 ^THESE COMMANDS MODIFY THE CASE OF THE CURRENT CHARACTER, IF IT
11100 IS A LETTER, AND THEN MOVE THE CURRENT CHARACTER POSITION
11200 ONE SPACE TO THE RIGHT.
11300 ^THE "_^" COMMAND INVERTS THE CASE, "_<" SETS IT TO UPPER CASE, AND
11400 "_>" SETS IT TO LOWER CASE.
11500 ^IF A REPEAT COUNT HAS BEEN SPECIFIED, THESE COMMANDS OPERATE ON
11600 THAT NUMBER OF CHARACTERS.
11700 ^IF A NEGATIVE SIGN ("-") HAS BEEN SPECIFIED, THESE COMMANDS OPERATE ON
11800 THE PREVIOUS CHARACTER AND THEN MOVE THE CURRENT CHARACTER
11900 POSITION ONE SPACE TO THE LEFT.
12000 ^A NEGATIVE REPEAT COUNT IS ALSO LEGAL.
00100 .BLANK 1
00200 .INDENT -6
00300 2.4.5 ^THE ^ALTER-MODE COMMAND "^B" IMMEDIATELY POSITIONS YOU
00400 TO THE BEGINNING OF THE CURRENT LINE.
00500 ^THIS COMMAND DIFFERS FROM "^L", WHICH ALSO POSITIONS YOU
00600 AT THE BEGINNING OF THE CURRENT LINE, IN THAT IT DOES NOT
00700 TYPE THE REMAINDER OF THE LINE BEFORE REPOSITIONING.
00800
00900 .BLANK 1
01000 .INDENT -6
01100 2.4.6 ^AN ^^ALTMODE\\ (^ESCAPE, OR ^^ESC\\ CHARACTER) IN ^ALTER
01200 MODE NOW CLEARS THE ACCUMULATED REPEAT COUNT AND NEGATIVE SIGN, IF
01300 ANY, WITHOUT RINGING THE TERMINAL'S AUDIBLE ALARM (BELL).
01400
01500 .BLANK 1
01600 .INDENT -6
01700 2.4.7 ^A GREATER NUMBER OF ^ALTER-MODE COMMANDS MAY BE
01800 USED WITH NEGATIVE REPEAT COUNTS. ^THESE INCLUDE "#" (SPACE FORWARDS),
01900 ^RUBOUT OR ^BACKSPACE (SPACE BACKWARDS),
02000 "@" (EXECUTE COMMAND FORWARDS - SEE 2.4.15, BELOW),
02100 "^D" (DELETE FORWARDS),
02200 "^R" (DELETE FORWARDS AND THEN INSERT), "^S" (SEARCH FORWARDS),
02300 "^K" (KILL NEXT CHARACTERS), "_<^H^T_>" (SPACE
02400 TO END OF LINE), AND "^X" (INSERT AT END OF LINE).
02500 ^WHEN A NEGATIVE SIGN ("-") OR NEGATIVE REPEAT COUNT ("-NN") IS GIVEN
02600 THE DIRECTION IN WHICH A COMMAND OPERATES IS REVERSED, E.G., "-^D"
02700 DELETES BACKWARDS INSTEAD OF FORWARDS, "-^X" INSERTS AT THE START OF
02800 THE LINE, ETC.
02900 ^NOTE IN THE PREVIOUS VERSION "_^^U" WAS ILLEGAL FOLLOWING A
03000 MINUS SIGN, WHICH PREVENTED THE USER FROM RESTORING THE ORIGINAL
03100 LINE UNDER CERTAIN COMMAND SEQUENCES.
03200
03300 .BLANK 1
03400 .INDENT -6
03500 2.4.8 ^AS FOR OTHER ^^SOS\\ MODES, TYPING TWO ^BELL CHARACTERS
03600 IN SUCCESSION ("_^^G_^^G") WILL NOW TERMINATE ALTER MODE AND RETURN
03700 YOU TO ^^SOS\\ COMMAND MODE (I.E., A "*" WILL BE TYPED).
03800 ^THE LINE CURRENTLY BEING ALTERED WILL REMAIN INTACT.
03900
04000 .BLANK 1
04100 .INDENT -6
04200 2.4.9 ^CONTROL CHARACTERS TYPED DURING ^ALTER MODE WILL
04300 NOW BE ECHOED AS SUCH (AS "_^_<CHAR_>").
04400
04500 .BLANK 1
04600 .INDENT -6
04700 2.4.10 ^FOR THE "^C", "^S", AND "^K" COMMANDS, THE ^CARRIAGE ^RETURN _<^C^R_>
04800 CHARACTER WILL NOW TERMINATE THE ^ALTER-MODE
04900 OPERATION ON THE CURRENT LINE, JUST AS ^CARRIAGE ^RETURN NOW
05000 TERMINATES OPERATIONS ON THE "^I" AND "^R" COMMANDS.
05100 ^SIMILARLY, THE ^^ALTMODE\\ (^ESCAPE, OR ^^ESC\\ CHARACTER) WILL TERMINATE
05200 THE "^C", "^S", OR "^K" OPERATION, JUST AS ^BACKSPACE OR ^RUBOUT
05300 DOES, BUT LEAVES YOU IN ^ALTER MODE ON THE CURRENT LINE AT THE CURRENT
05400 POSITION.
05500
05600 .BLANK 1
05700 .INDENT -6
05800 2.4.11 ^FOR THE "^S" AND "^K" COMMANDS, THE INITIAL CHARACTER POSITION
05900 MAY BE THOUGHT OF AS BEING BEFORE THE FIRST CHARACTER POSITION
06000 ON THE LINE, SO THAT AN ^S COMMAND FOR THE FIRST CHARACTER IN
06100 THE LINE WILL FIND IT, AND A ^K COMMAND FOR THE FIRST
06200 CHARACTER WILL NOT KILL ANY CHARACTERS.
06300 ^THIS MAKES ^ALTER MODE OPERATIONS MORE CONSISTENT SINCE, FOR
06400 EXAMPLE, IN A ^^FORTRAN\\ PROGRAM, A SEARCH FOR A HORIZONTAL
06500 TAB CHARACTER (E.G., TYPING "^S_<^H^T_>") AT THE BEGINNING OF THE LINE WILL ALWAYS
06600 PUT YOU AT COLUMN 7, WHETHER OR NOT THE LINE HAS A ^^FORTRAN\\
06700 STATEMENT NUMBER.
06800
06900 .BLANK 1
07000 .INDENT -6
07100 2.4.12 ^THE "^T", "^W", "^U", AND "^X" ^ALTER-MODE COMMANDS HAVE
07200 BEEN CHANGED FROM PRIOR VERSIONS TO PROVIDE GREATER WORD-HANDLING
07300 CAPABILITY AND TO MAKE ^ALTER MODE MORE CONSISTENT WITH OTHER ^^SOS\\
07400 COMMANDS.
07500 "^W" RETAINS ITS PRESENT MEANING OF "SKIP NEXT WORD";
07600 A WORD IS DEFINED AS ANY COLLECTION OF LETTERS,
07700 NUMBERS, AND THE THREE SEPARATOR-TYPE SPECIAL CHARACTERS ".", "%",
07800 AND "$".
07900 ^IN VERSION 23(220), "^T" MEANS "DELETE NEXT WORD AND INSERT TEXT";
08000 _"^U" MEANS "DELETE NEXT WORD";
08100 "^X" MEANS "SKIP TO END OF LINE AND INSERT TEXT", ANALOGOUS TO THE
08200 NORMAL "^X" (^EXTEND) COMMAND.
08300 ^NOTE THAT "-^X" IS A LEGAL COMMAND MEANING "SKIP TO BEGINNING OF
08400 LINE AND INSERT TEXT".
08500 ^FOR BOTH "^T" AND "^X" TEXT IS INSERTED UNTIL AN ^ALTMODE" OR _<^^CR\\_>
08600 IS TYPED.
08700 .BLANK 1
08800 ^THIS IMPLEMENTATION REPLACES THE PRIOR VERSION IN WHICH "^X" MEANT
08900 "DELETE WORD AND INSERT TEXT" (CURRENT "^T" FUNCTION ) AND "^T"
09000 AND "^U" WERE ERRORS.
09100
09200 .BLANK 1
09300 .INDENT -6
09400 2.4.13 ^IN ^EXPERT MODE, TEXT BACKSPACED ACROSS (IN RESPONSE TO A "_<^^RO\\_>",
09500 "-_<^^SP\\_>", OR "-^S" COMMAND) IS NOT TYPED WHEN THE RESULT WOULD
09600 BE THAT THE CHARACTER POINTER WILL BE AT THE START OF THE LINE.
09700 ^INSTEAD, THE LINE NUMBER IS AGAIN TYPED TO INDICATE THIS RESULT.
09800
09900 .BLANK 1
10000 .INDENT -6
10100 2.4.14 ^FOR THE "^K", "^S", AND "^C" COMMANDS, THE ^LINE-FEED CHARACTER
10200 ("_<^^LF\\_>") HAS BEEN GIVEN A SPECIAL MEANING "END OF LINE".
10300 ^THUS, "^K_<^^LF\\_>" KILLS ALL CHARACTERS TO END OF LINE (BEGINNING OF
10400 LINE IF "-^K"); AND "^S" SEARCHES TO THE END OF LINE (BEGINNING OF LINE
10500 IF "-^S").
10600 ^CHANGING A CHARACTER TO A LINE FEED WITH "^C_<^^LF\\_>" NOW INSERTS AN
10700 _<^^CR\\_>_<^^LF\\_> AND COPIES THE REMAINING TEXT TO A NEW LINE,
10800 ANALOGOUS THE INSERTION OF A _<^^LF\\_> WITH THE "^I", "^R",
10900 "^T", OR "^X" COMMAND.
11000
11100 .BLANK 1
11200 .INDENT -6
11300 2.4.15 ^AN IMPORTANT EXTENSION TO THE ^ALTER MODE COMMAND
11400 FACILITY HAS BEEN IMPLEMENTED.
11500 ^THIS IS THE "^EXECUTE THROUGH" COMMAND ("_@"), WHICH HAS THE SYNTAX

11700 .INDENT 6
11800 _[-_]##_[NN_]##@##_<CMD_>##_<CHAR_>
11900 .BLANK 1
12000 AND SPECIFIES TO EXECUTE THE ^ALTER MODE COMMAND "_<CMD_>"
12100 THROUGH THE "NN"TH OCCURRENCE OF "_<CHAR_>".
12200 ^THE COMMAND SEARCHES BACKWARDS IF THE MINUS SIGN HAS BEEN
12300 SPECIFIED AND IF MINUS IS LEGAL FOR THE SPECIFIED "_<CMD_>".
12400 ^THIS COMMAND SUPPORTS THE FOLLOWING COMMAND CHARACTERS:
12500 _"#" ("@#<CHAR>" IS EQUIVALENT TO "^S<CHAR>"),
12600 _"^C", "_^", "_>", "_<", "^D" ("@^D<CHAR>" IS EQUIVALENT TO "^K<CHAR>"),
12700 AND "^V" (SEE 2.4.19, BELOW).
12800 ^ALL COMMANDS EXCEPT "^C" AND "^V" MAY SEARCH IN EITHER DIRECTION;
12900 ONLY THE "#" COMMAND MAY BE USED WHEN SEARCHING A _/^^READONLY\\
13000 FILE.
13100 ^THE "@" COMMAND FOLLOWS THE NEW CONVENTION FOR INITIAL CHARACTER
13200 POSITION DESCRIBED IN 2.4.11 AND OBEYS THE ADDED SPECIAL-CHARACTER
13300 CONVENTIONS FOR ^CARRIAGE ^RETURN, ^ALTMODE, ^BACKSPACE, ^RUBOUT,
13400 ^LINE ^FEED, _^^R, AND _^^U DESCRIBED IN 2.4..1, 2.4.2, 2.4.3,

14000 THE "^S", "^K", AND "@" COMMANDS, HAS BEEN IMPROVED.
14100 .BLANK 1
14200 ^FIRST, LETTER COMPARISONS WILL BE EITHER EXACT (UPPER CASE
14300 DISTINCT FROM LOWER CASE) OR FOLDED (UPPER CASE AND LOWER CASE
14400 ARE EQUAL) DEPENDING ON THE SETTING OF THE "_/^^EXACT\\" SWITCH

14700 ^SECOND, ALL PATTERN MATCH SPECIAL CHARACTERS AS DESCRIBED IN
14800 ITEM 2.29, BELOW, EXCEPT "ANY NUMBER OF" AND "ONE OR MORE OF",
14900 MAY BE USED AS TARGET CHARACTERS.
15000 ^THIS MEANS, FOR EXAMPLE, THAT THE COMMAND "^K_?_:" WHEN IN
