  I'm sorry I'm not good at writing in English.
I hope you to understand the followings.

  The schedule file is "STATIC\SCHEDULE.DAT".  I am going to introduce
you about the structure of this file.

  ===[ Think as Header ]===

  Offset  Length    Description
  ------  --------  ---------------------------------------------------
     00H        4    256 in Ultima 7 & 7.5.   NPC num.
                     (Next header item size(byte) is affected by this.)
     04H    NUM*2    Same as the SUM of each NPC's schedule amount.
                     (Because NUM is 256 in Ultima 7 & 7.5,
                      the size is 512 bytes in Ultima 7 & 7.5. )

  ===[ Think as Body ]===

   Each schedule size(byte) is 4 byte.

   XX XX XX XX
   |  |  |  +------ SuperChunk Number
   |  |  +--------- Y coordinate in the SuperChunk.
   |  +------------ X coordinate in the SuperChunk.
   +--------------- Schedule number & Match time.

   You can see the real X, Y location in cheat mode.
      SuperChunk Number = (Real-Y / 256) * 12 + (Real-X / 256)
                      X = (Real-X % 256)
                      Y = (Real-Y % 256)
      *. '%' is the same keyword as in C.
   You can get them(SuperChunk Number, X, Y) easily by hex.

   The followings are about Schedule number & Match time byte.
     7  6  5  4  3  2  1  0 Bit
   +--+--+--+--+--+--+--+--+
   |  |  |  |  |  |  |  |  |
   +--+--+--+--+--+--+--+--+
    [============] [======]
     Schedule num   Match time
      ( 5 bit )     ( 3 bit )

     Match time: 000= 0 AM,    100= 0 PM
                 001= 3 AM,    101= 3 PM
                 010= 6 AM,    110= 6 PM
                 011= 9 AM,    111= 9 PM
     Schedule num:
        0= Combat       9= Hound        18= Bake       27= Duel
        1= Hor. Pace   10= Stand        19= Sew        28= Preach
        2= Ver. Pace   11= Loiter       20= Shy        29= Patrol
        3= Talk        12= Wander       21= Lab        30= Desk Work
        4= Dance       13= Blacksmith   22= Thief      31= Follow Avt
        5= Eat         14= Sleep        23= Waiter
        6= Farm        15= Wait         24= Special
        7= Tend Shop   16= Major Sit    25= Kid Games
        8= Miner       17= Graze        26= Eat at Inn

   Avatar has no schedule.  And each NPC must have 1 schedule at least.
 Surely 8 is max amount for one NPC.

  If you are not able to understand above, run Ultima 7 or 7.5 at cheat mode
 and check the NPC schedule.

-- End.
