/ NOTES:

/ N. A. MEANS NOT APPLICABLE TO SOURCE FILES AS ARE USED BY PAL,
/ FOCAL, ETC. AND ARE NOT CONVERTED BY THE PREVAILING INTER-
/ SYSTEM CONVERSION PROGRAMS.

/ LOWER-CASE LETTERS ARE FOLDED TO UPPER-CASE LETTERS FOR P?S/8
/ SIX-BIT FILES.

/ A) CHARACTERS ARE GENERALLY IGNORED BY ALL SYSTEMS
/ AND ARE KNOWN TO BE USED AS PAD CHARACTERS BY VARIOUS OS/8
/ PROGRAMS ONLY TO BE DELETED BY MOST OS/8 UTILITIES.

/ B) WHILE RUNNING SYSTEM PROGRAMS: , <^A>,
/ <^B>, AND <^C> RETURN TO P?S/8 MONITOR (GENERALLY).
/ RETURNS TO OS/8 (USUALLY) AND RETURNS TO P?S/8 MONITOR
/ ALSO CANCELLING BATCH OPERATIONS (IF RUNNING UNDER P?S/8 BATCH).

/ C) <^A> IS THE "SEARCH AGAIN" CHARACTER IN THE P?S/8 "EDIT"
/ COMMAND.

/ D) <^C> TERMINATES ALL PRINTOUT WITHIN THE ENVIRONMENT OF THE
/ KEYBOARD MONITOR, AND CAN ALSO TERMINATE AUTO-SEQUENCED INPUT
/ (EQUIVALENT TO _{<^Z> IN THIS ONE CONTEXT). <^C> ALSO
/ TERMINATES ALL BATCH OPERATIONS AS WELL AS ABORTING ALL SYSTEM
/ PROGRAMS, AND WILL PRINT "^C" ON THE SYSTEM CONSOLE WHEN USED FOR
/ THIS PURPOSE.

/ E) <^D> WAS FORMERLY THE PERMANENT "END OF SEQUENCED-INPUT"
/ CHARACTER IN THE P?S/8 LINE EDITOR PRIOR TO VERSION 8Y. IT IS NOW
/ SUPERSEDED BY _{<^Z>.

/ F) <^F> IS THE "FINISH LINE" CHARACTER IN THE P?S/8 "EDIT"
/ COMMAND.

/ G) <^G> IS THE "ENTER SEARCH" CHARACTER IN THE P?S/8 "EDIT"
/ COMMAND.

/ H) <^J> IS CONVERTED FROM OS/8 TO P?S/8 SIX-BIT DIRECTLY. OS/8
/ CARRIAGE RETURNS ARE DELETED. P?S/8 EDITING INSERTS <^J> INTO
/ FILES WHEN <^M> OR IS STRUCK, THUS INTERNALLY
/ <^J> IS USED AS "END OF LINE" CHARACTER (SEPARATE CARRIAGE-
/ RETURN AND LINE-FEED CHARACTERS DO NOT EXIST IN P?S/8 SIX-BIT FILES).
/ P?S/8 TO OS/8 CONVERSION OF <^J> INSERTS <^M> FOLLOWED
/ BY <^J> INTO THE OS/8 FILE. LAP6-DIAL FILES USE 43 AS
/ BUT IMPLY "END OF LINE" AS IN P?S/8 FILES AND ARE TRANSLATED
/ ACCORDINGLY. LAP6-DIAL FILES SELDOM CONTAIN 37 OR
/ BECAUSE LAP6-DIAL'S EDITOR USES THIS CHARACTER AS A
/ VISUAL TO ENTER COMMAND MODE. LAP6-DIAL FILES CAN ACTUALLY
/ CONTAIN THIS CHARACTER IF A CONVERSION PROGRAM OR "TRICKED" LAP6-DIAL
/ SYSTEM CREATES IT.

/ I) <^K> IS THE "KILL FROM BEGINNING" CHARACTER IN THE P?S/8
/ "EDIT" COMMAND.
/ J) <^L> IS CONVERTED OPTIONALLY FROM OS/8 TO P?S/8 SIX-BIT AS
/ "EJECT" TO CONFORM TO RULES OF THE PAL LANGUAGE "EJECT"
/ PSEUDO-OP. THIS IS TOTALLY LANGUAGE COMPATIBLE EXCEPT WHERE THE
/ ORIGINAL FORM-FEED WAS WITHIN A MULTIPLE PAGE AREA OF FAILING
/ CONDITIONAL ASSEMBLY (WHICH IS BEING PRINTED WHILE BEING IGNORED
/ BY THE ASSEMBLER) WHICH IN OS/8 WILL PRINT ON A NEW PAGE AND WILL
/ BE SEEN AS "EJECT" ON A P?S/8 PAL LISTING. N.B.,
/ EXECUTED "EJECT" STATEMENTS (NOT FAILING CONDITIONAL ASSEMBLY)
/ WILL ALWAYS DO THE EQUIVALENT FUNCTION. "EJECT" IS
/ CONVERTED OPTIONALLY FROM P?S/8 SIX-BIT TO OS/8 AS .

/ K) <^O> IS USED TO INVERT PRINTING STATUS BY NUMEROUS P?S/8
/ AND OS/8 PROGRAMS. GENERALLY OS/8 PROGRAMS USE <^O> TO
/ EITHER JUST TURN PRINTING OFF OR PERHAPS WAIT FOR ANOTHER
/ (DIFFERENT) CHARACTER TO RESTORE PRINTING. THE PREVAILING P?S/8
/ CONVENTION IS TO USE <^O> AS A PRINT/NO-PRINT FLIP-FLOP
/ (AS IN PDP-10 TOPS-10).

/ L) <^P> IS USED TO ABORT AND RESTART MANY P?S/8 AND OS/8
/ SYSTEM PROGRAMS.

/ M) <^Q> AND <^S> ARE USED TO UN-FREEZE AND FREEZE,
/ RESPECTIVELY, ALL P?S/8 SYSTEM OUTPUT (AT USER OPTION, OR AS REQUIRED
/ BY THE SYSTEM CONSOLE (DEC VT-100 OR LA-120, ETC.)). THIS IS SOMETIMES
/ KNOWN AS "XON/XOFF" PROTOCOL.

/ N) <^R> AND <^T> ARE USED TO REWIND AND UNLOAD THE CURRENT
/ SYSTEM DEVICE UNIT.

/ O) <^U> IS USED TO CANCEL COMMAND INPUT IN ALL P?S/8 AND OS/8
/ KEYBOARD COMMANDS.

/ P) _{<^Z> IS THE P?S/8 LINE EDITOR "END-OF-SEQUENCED-INPUT" CHARACTER
/ AND ALSO THE OS/8 (AND VARIOUS OTHER SYSTEMS') END-OF-FILE CHARACTER.

/ Q) IS USED AS IN THE KEYBOARD MONITOR ( IS
/ INSERTED AS END OF LINE). WHEN PRINTED BY THE KEYBOARD MONITOR,
/ IS PRINTED AS "$" WITH NO , . THE
/ CODE IS SOMETIMES FOUND ON VARIOUS TERMINALS TO BE 175 OR
/ 176 (AS WELL AS 033). THE "SET" COMMAND CAN BE USED TO VARY
/ THE DESIGNATED INPUT CODE FOR AS WELL AS THE ACTION
/ TAKEN ON ITS DETECTION.

/ R) (OR ON NEWER TERMINALS) IS USED AS A
/ RUBOUT FUNCTION IN THE P?S/8 KEYBOARD MONITOR. IT IS A VALID
/ CHARACTER WITHIN A LAP6-DIAL FILE. SEE NOTE H.

/ S) IS USED IN THE P?S/8 KEYBOARD MONITOR TO DO A RUBOUT
/ FUNCTION. OS/8 FILES SOMETIMES PAD SOURCE FILES WITH EXTRANEOUS
/ CHARACTERS AS PARTIAL FILLER CHARACTERS NOT
/ NECESSARILY FUNCTIONAL ON MODEL 35 TELETYPES, ETC. WHICH ACTUALLY
/ REQUIRE VARIABLE FILLERS (0-2 FILLER CHARACTERS AS NECESSARY).

$ /THAT'S ALL FOLK!}}}}
