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