C  ADVENTURES

C  CURRENT LIMITS:
C      9650 WORDS OF MESSAGE TEXT (LINES, LINSIZ).
C	750 TRAVEL OPTIONS (TRAVEL, TRVSIZ).
C	300 VOCABULARY WORDS (KTAB, ATAB, TABSIZ).
C	150 LOCATIONS (LTEXT, STEXT, KEY, COND, ABB, ATLOC, LOCSIZ).
C	100 OBJECTS (PLAC, PLACE, FIXD, FIXED, LINK (TWICE), PTEXT, PROP).
C	 35 "ACTION" VERBS (ACTSPK, VRBSIZ).
C	205 RANDOM MESSAGES (RTEXT, RTXSIZ).
C	 12 DIFFERENT PLAYER CLASSIFICATIONS (CTEXT, CVAL, CLSMAX).
C	 20 HINTS, LESS 3 (HINTLC, HINTED, HINTS, HNTSIZ).
C	 35 MAGIC MESSAGES (MTEXT, MAGSIZ).
C  THERE ARE ALSO LIMITS WHICH CANNOT BE EXCEEDED DUE TO THE STRUCTURE OF
C  THE DATABASE.  (E.G., THE VOCABULARY USES N/1000 TO DETERMINE WORD TYPE,
C  SO THERE CAN'T BE MORE THAN 1000 WORDS.)  THESE UPPER LIMITS ARE:
C	1000 NON-SYNONYMOUS VOCABULARY WORDS
C	300 LOCATIONS
C	100 OBJECTS

C DESCRIPTION OF THE DATABASE FORMAT
C
C
C  THE DATA FILE CONTAINS SEVERAL SECTIONS.  EACH BEGINS WITH A LINE CONTAINING
C  A NUMBER IDENTIFYING THE SECTION, AND ENDS WITH A LINE CONTAINING "-1".
C
C  SECTION 1: LONG FORM DESCRIPTIONS.  EACH LINE CONTAINS A LOCATION NUMBER,
C	A TAB, AND A LINE OF TEXT.  THE SET OF (NECESSARILY ADJACENT) LINES
C	WHOSE NUMBERS ARE X FORM THE LONG DESCRIPTION OF LOCATION X.
C  SECTION 2: SHORT FORM DESCRIPTIONS.	SAME FORMAT AS LONG FORM.  NOT ALL
C	PLACES HAVE SHORT DESCRIPTIONS.
C  SECTION 3: TRAVEL TABLE.  EACH LINE CONTAINS A LOCATION NUMBER (X), A SECOND
C	LOCATION NUMBER (Y), AND A LIST OF MOTION NUMBERS (SEE SECTION 4).
C	EACH MOTION REPRESENTS A VERB WHICH WILL GO TO Y IF CURRENTLY AT X.
C	Y, IN TURN, IS INTERPRETED AS FOLLOWS.	LET M=Y/1000, N=Y MOD 1000.
C		IF N<=300	IT IS THE LOCATION TO GO TO.
C		IF 300<N<=500	N-300 IS USED IN A COMPUTED GOTO TO
C					A SECTION OF SPECIAL CODE.
C		IF N>500	MESSAGE N-500 FROM SECTION 6 IS PRINTED,
C					AND HE STAYS WHEREVER HE IS.
C	MEANWHILE, M SPECIFIES THE CONDITIONS ON THE MOTION.
C		IF M=0		IT'S UNCONDITIONAL.
C		IF 0<M<100	IT IS DONE WITH M% PROBABILITY.
C		IF M=100	UNCONDITIONAL, BUT FORBIDDEN TO DWARVES.
C		IF 100<M<=200	HE MUST BE CARRYING OBJECT M-100.
C		IF 200<M<=300	MUST BE CARRYING OR IN SAME ROOM AS M-200.
C		IF 300<M<=400	PROP(M MOD 100) MUST *NOT* BE 0.
C		IF 400<M<=500	PROP(M MOD 100) MUST *NOT* BE 1.
C		IF 500<M<=600	PROP(M MOD 100) MUST *NOT* BE 2, ETC.
C	IF THE CONDITION (IF ANY) IS NOT MET, THEN THE NEXT *DIFFERENT*
C	"DESTINATION" VALUE IS USED (UNLESS IT FAILS TO MEET *ITS* CONDITIONS,
C	IN WHICH CASE THE NEXT IS FOUND, ETC.).  TYPICALLY, THE NEXT DEST WILL
C	BE FOR ONE OF THE SAME VERBS, SO THAT ITS ONLY USE IS AS THE ALTERNATE
C	DESTINATION FOR THOSE VERBS.  FOR INSTANCE:
C		15	110022	29	31	34	35	23	43
C		15	14	29
C	THIS SAYS THAT, FROM LOC 15, ANY OF THE VERBS 29, 31, ETC., WILL TAKE
C	HIM TO 22 IF HE'S CARRYING OBJECT 10, AND OTHERWISE WILL GO TO 14.
C		11	303008	49
C		11	9	50
C	THIS SAYS THAT, FROM 11, 49 TAKES HIM TO 8 UNLESS PROP(3)=0, IN WHICH
C	CASE HE GOES TO 9.  VERB 50 TAKES HIM TO 9 REGARDLESS OF PROP(3).
C  SECTION 4: VOCABULARY.  EACH LINE CONTAINS A NUMBER (N), A TAB, AND A
C	FIVE-LETTER WORD.  CALL M=N/1000.  IF M=0, THEN THE WORD IS A MOTION
C	VERB FOR USE IN TRAVELLING (SEE SECTION 3).  ELSE, IF M=1, THE WORD IS
C	AN OBJECT.  ELSE, IF M=2, THE WORD IS AN ACTION VERB (SUCH AS "CARRY"
C	OR "ATTACK").  ELSE, IF M=3, THE WORD IS A SPECIAL CASE VERB (SUCH AS
C	"DIG") AND N MOD 1000 IS AN INDEX INTO SECTION 6.  OBJECTS FROM 50 TO
C	(CURRENTLY, ANYWAY) 79 ARE CONSIDERED TREASURES (FOR PIRATE, CLOSEOUT).
C  SECTION 5: OBJECT DESCRIPTIONS.  EACH LINE CONTAINS A NUMBER (N), A TAB,
C	AND A MESSAGE.	IF N IS FROM 1 TO 100, THE MESSAGE IS THE "INVENTORY"
C	MESSAGE FOR OBJECT N.  OTHERWISE, N SHOULD BE 000, 100, 200, ETC., AND
C	THE MESSAGE SHOULD BE THE DESCRIPTION OF THE PRECEDING OBJECT WHEN ITS
C	PROP VALUE IS N/100.  THE N/100 IS USED ONLY TO DISTINGUISH MULTIPLE
C	MESSAGES FROM MULTI-LINE MESSAGES; THE PROP INFO ACTUALLY REQUIRES ALL
C	MESSAGES FOR AN OBJECT TO BE PRESENT AND CONSECUTIVE.  PROPERTIES WHICH
C	PRODUCE NO MESSAGE SHOULD BE GIVEN THE MESSAGE ">$<".
C  SECTION 6: ARBITRARY MESSAGES.  SAME FORMAT AS SECTIONS 1, 2, AND 5, EXCEPT
C	THE NUMBERS BEAR NO RELATION TO ANYTHING (EXCEPT FOR SPECIAL VERBS
C	IN SECTION 4).
C  SECTION 7: OBJECT LOCATIONS.  EACH LINE CONTAINS AN OBJECT NUMBER AND ITS
C	INITIAL LOCATION (ZERO (OR OMITTED) IF NONE).  IF THE OBJECT IS
C	IMMOVABLE, THE LOCATION IS FOLLOWED BY A "-1".	IF IT HAS TWO LOCATIONS
C	(E.G. THE GRATE) THE FIRST LOCATION IS FOLLOWED WITH THE SECOND, AND
C	THE OBJECT IS ASSUMED TO BE IMMOVABLE.
C  SECTION 8: ACTION DEFAULTS.	EACH LINE CONTAINS AN "ACTION-VERB" NUMBER AND
C	THE INDEX (IN SECTION 6) OF THE DEFAULT MESSAGE FOR THE VERB.
C  SECTION 9: LIQUID ASSETS, ETC.  EACH LINE CONTAINS A NUMBER (N) AND UP TO 20
C	LOCATION NUMBERS.  BIT N (WHERE 0 IS THE UNITS BIT) IS SET IN COND(LOC)
C	FOR EACH LOC GIVEN.  THE COND BITS CURRENTLY ASSIGNED ARE:
C		0	LIGHT
C		1	IF BIT 2 IS ON: ON FOR OIL, OFF FOR WATER
C		2	LIQUID ASSET, SEE BIT 1
C		3	PIRATE DOESN'T GO HERE UNLESS FOLLOWING PLAYER
C	OTHER BITS ARE USED TO INDICATE AREAS OF INTEREST TO "HINT" ROUTINES:
C		4	TRYING TO GET INTO CAVE
C		5	TRYING TO CATCH BIRD
C		6	TRYING TO DEAL WITH SNAKE
C		7	LOST IN MAZE
C		8	PONDERING DARK ROOM
C		9	AT WITT'S END
C	COND(LOC) IS SET TO 2, OVERRIDING ALL OTHER BITS, IF LOC HAS FORCED
C	MOTION.
C  SECTION 10: CLASS MESSAGES.	EACH LINE CONTAINS A NUMBER (N), A TAB, AND A
C	MESSAGE DESCRIBING A CLASSIFICATION OF PLAYER.	THE SCORING SECTION
C	SELECTS THE APPROPRIATE MESSAGE, WHERE EACH MESSAGE IS CONSIDERED TO
C	APPLY TO PLAYERS WHOSE SCORES ARE HIGHER THAN THE PREVIOUS N BUT NOT
C	HIGHER THAN THIS N.  NOTE THAT THESE SCORES PROBABLY CHANGE WITH EVERY
C	MODIFICATION (AND PARTICULARLY EXPANSION) OF THE PROGRAM.
C  SECTION 11: HINTS.  EACH LINE CONTAINS A HINT NUMBER (CORRESPONDING TO A
C	COND BIT, SEE SECTION 9), THE NUMBER OF TURNS HE MUST BE AT THE RIGHT
C	LOC(S) BEFORE TRIGGERING THE HINT, THE POINTS DEDUCTED FOR TAKING THE
C	HINT, THE MESSAGE NUMBER (SECTION 6) OF THE QUESTION, AND THE MESSAGE
C	NUMBER OF THE HINT.  THESE VALUES ARE STASHED IN THE "HINTS" ARRAY.
C	HNTMAX IS SET TO THE MAX HINT NUMBER (<= HNTSIZ).  NUMBERS 1-3 ARE
C	UNUSABLE SINCE COND BITS ARE OTHERWISE ASSIGNED, SO 2 IS USED TO
C	REMEMBER IF HE'S READ THE CLUE IN THE REPOSITORY, AND 3 IS USED TO
C	REMEMBER WHETHER HE ASKED FOR INSTRUCTIONS (GETS MORE TURNS, BUT LOSES
C	POINTS).
C  SECTION 12: MAGIC MESSAGES. IDENTICAL TO SECTION 6 EXCEPT PUT IN A SEPARATE
C	SECTION FOR EASIER REFERENCE.  MAGIC MESSAGES ARE USED BY THE STARTUP,
C	MAINTENANCE MODE, AND RELATED ROUTINES.
C  SECTION 0: END OF DATABASE.
C  READ THE DATABASE IF WE HAVE NOT YET DONE SO

C  CAVE CLOSING AND SCORING


C  THESE SECTIONS HANDLE THE CLOSING OF THE CAVE.  THE CAVE CLOSES "CLOCK1"
C  TURNS AFTER THE LAST TREASURE HAS BEEN LOCATED (INCLUDING THE PIRATE'S
C  CHEST, WHICH MAY OF COURSE NEVER SHOW UP).  NOTE THAT THE TREASURES NEED NOT
C  HAVE BEEN TAKEN YET, JUST LOCATED.  HENCE CLOCK1 MUST BE LARGE ENOUGH TO GET
C  OUT OF THE CAVE (IT ONLY TICKS WHILE INSIDE THE CAVE).  WHEN IT HITS ZERO,
C  WE BRANCH TO 10000 TO START CLOSING THE CAVE, AND THEN SIT BACK AND WAIT FOR
C  HIM TO TRY TO GET OUT.  IF HE DOESN'T WITHIN CLOCK2 TURNS, WE CLOSE THE
C  CAVE; IF HE DOES TRY, WE ASSUME HE PANICS, AND GIVE HIM A FEW ADDITIONAL
C  TURNS TO GET FRANTIC BEFORE WE CLOSE.  WHEN CLOCK2 HITS ZERO, WE BRANCH TO
C  11000 TO TRANSPORT HIM INTO THE FINAL PUZZLE.  NOTE THAT THE PUZZLE DEPENDS
C  UPON ALL SORTS OF RANDOM THINGS.  FOR INSTANCE, THERE MUST BE NO WATER OR
C  OIL, SINCE THERE ARE BEANSTALKS WHICH WE DON'T WANT TO BE ABLE TO WATER,
C  SINCE THE CODE CAN'T HANDLE IT.  ALSO, WE CAN HAVE NO KEYS, SINCE THERE IS A
C  GRATE (HAVING MOVED THE FIXED OBJECT!) THERE SEPARATING HIM FROM ALL THE
C  TREASURES.  MOST OF THESE PROBLEMS ARISE FROM THE USE OF NEGATIVE PROP
C  NUMBERS TO SUPPRESS THE OBJECT DESCRIPTIONS UNTIL HE'S ACTUALLY MOVED THE
C  OBJECTS.

C  WHEN THE FIRST WARNING COMES, WE LOCK THE GRATE, DESTROY THE BRIDGE, KILL
C  ALL THE DWARVES (AND THE PIRATE), REMOVE THE TROLL AND BEAR (UNLESS DEAD),
C  AND SET "CLOSNG" TO TRUE.  LEAVE THE DRAGON; TOO MUCH TROUBLE TO MOVE IT.
C  FROM NOW UNTIL CLOCK2 RUNS OUT, HE CANNOT UNLOCK THE GRATE, MOVE TO ANY
C  LOCATION OUTSIDE THE CAVE (LOC<9), OR CREATE THE BRIDGE.  NOR CAN HE BE
C  RESURRECTED IF HE DIES.  NOTE THAT THE SNAKE IS ALREADY GONE, SINCE HE GOT
C  TO THE TREASURE ACCESSIBLE ONLY VIA THE HALL OF THE MT. KING.  ALSO, HE'S
C  BEEN IN GIANT ROOM (TO GET EGGS), SO WE CAN REFER TO IT.  ALSO ALSO, HE'S
C  GOTTEN THE PEARL, SO WE KNOW THE BIVALVE IS AN OYSTER.  *AND*, THE DWARVES
C  MUST HAVE BEEN ACTIVATED, SINCE WE'VE FOUND CHEST.
