Part 12 - The End Game

To decide what indexed text is the encryption of (x - an indexed text):

let keyw be {5, 3, 15, 22, 24, 18, 13, 19};

let outw be an indexed text;

let uinws be 0;

let usum be 0;

let inw be a list of numbers;

let i be 1;

let j be 1;

now outw is "[8 spaces]";

let len be the number of characters in x;

let a be character number 1 in x; [ to appease scoping rules ]

while i is at most 8 begin;

all, dispelling the darkness of ignorance and danger. One such as

yourself is fit to join even the Implementers!' He then raises his

laughter fading in the distance.".

It is difficult to see through the smoke and flame which fills the pit, but it seems to be more or less bottomless. It also extends upward out of sight. The pit itself is of roughly dressed stone and circular in shape. It is about two hundred feet in diameter. The flames generate considerable heat, so it is rather uncomfortable standing here.

There is an object here which looks like a sundial. On it are an indicator arrow and (in the center) a large button. On the face of the dial are numbers 'one' through 'eight'. The indicator points to the number [dial number in words]."

[5 spaces]There are chests here containing precious jewels, mountains of

zorkmids, rare paintings, ancient statuary, and beguiling curios.[paragraph break]

[5 spaces]In one corner of the room is a bookcase boasting such volumes as

'The History of the Great Underground Empire,' 'The Lives of the

Twelve Flatheads,' 'The Wisdom of the Implementors,' and other

informative and inspiring works.[paragraph break]

[5 spaces]On one wall is a completely annotated map of the Great Underground

[5 spaces]On a desk at the far end of the room may be found stock

Last every turn rule:

if the player is in Treasury of Zork begin;

award 35 points;

say "[5 spaces]As you gleefully examine your new-found riches, the Dungeon

Master himself materializes beside you, and says, 'Now that you have solved all the mysteries of the Dungeon, it is time for you to assume your rightly-earned place in the scheme of things. Long have I waited for one capable of releasing me from my burden!' He taps you lightly on the head with his staff, mumbling a few well-chosen spells,

and you feel yourself changing, growing older and more stooped. For a moment there are two identical mages staring at each other among the treasure, then you watch as your counterpart dissolves into a mist and disappears, a sardonic grin on his face.";

end the game in victory;

end if.

if the player is in Prison Cell, move the player to PCell;

now every thing in Prison Cell is in Limbo;

if the cell number of the player is dial number and the player is in PCell or the player is in NCell, move the player to Prison Cell;

if the player is in PCell and the cell number of the thingy is the cell number of the player, move the thingy to PCell;
