PLAYING THE GAME



In an adventure game, you play by typing commands that describe what you want

to do.  Unfortunately, the game isn't as smart as you are, so it can't

understand nearly as many sentences as a person could.  In this section,

we'll describe most of the types of commands that you will need to use while

playing the game.



Each time you see the prompt, ">", you type a command.  Your command should

be a simple imperative sentence, or a series of imperatives separated by

periods.  Press the RETURN (or ENTER) key when you are done typing your

command; the game doesn't start interpreting the command until you press RETURN.



You can use capital or small letters in any mixture.  You can use words such

as THE and AN when they're appropriate, but you can omit them if you prefer.

You can abbreviate any word to six or more letters, but the game will pay

attention to all of the letters you type.  For example, you could refer to

a FLASHLIGHT with the words FLASHL, FLASHLIG, and so forth, but not with

FLASHSDF.





TRAVEL



At any time during the game, you are in a location.  The game desribes your

location when you first enter, and again any time you type LOOK.  In a given

location, you can reach anything described, so you don't need to type commands

to move about within a location.



You move from place to place in the game by typing the direction you want to

go.  The game will always tell you the directions that you can go from a location,

although it usually doesn't tell you what you will find when you go there.  You

will probably find it helpful to make a map as you explore the game.  The

directions the game recognizes are NORTH, SOUTH, EAST, WEST, NORTHEAST,

SOUTHEAST, UP, and DOWN.  You can abbreviate these to N, S, E, W, NE, SE, NW,

SW, U, and D.  In some locations you can also use IN and OUT.



Generally, backtracking will take you back to where you started.  For example,

if you start off in the kitchen, go north into the living room, then go south,

you will be back in the kitchen.



Most of the time, when the game describes a door or doorway, you don't need to

open the door to go through the passage; the game will do this for you.  Only

when the game explicitly describes a closed door (or other impediment to travel)

will you need to type a command to open the door.





OBJECTS



In the game, you will find many objects that you can carry or otherwise

manipulate.  When you want to do something with an object, type a simple

command that tells the game what you want to do; be explicit.  For example,

you could type READ THE BOOK or OPEN THE DRAWER.  Most of the objects in the

game have fairly obvious uses; you shouldn't have to think of any obscure or

unrelated words to manipulate the objects.



You generally don't have to specify exactly where you want to put an object

that you wish to carry; you can just type TAKE (followed by the object's

name) to carry an object.  We didn't think it was particularly interesting

to force you to specify which object you wish to put in your left pocket,

which you wish to carry in your right hand, and so forth.  However, there

is a limit to how many objects you can carry at once, and to how much weight

you can handle.  You can carry more objects (but not more weight, of course)

by putting some items inside containers (for example, you may be able to put

several objects into a box, and carry the box), since this reduces the number

of objects you actually have to juggle at once.



Some basic verbs that you will use frequently are TAKE (to pick up an object),

DROP (to drop an object), OPEN and CLOSE, and EXAMINE (which you can abbreviate

to X).  You can PUT an object IN or ON another object when appropriate.  The

game recognizes many other verbs as well.  We tried to make all of the verbs

obvious; if you find a knob, you will be able to TURN it, and if you find a

button, you will be able to PUSH it.  By the same token, you probably won't

need to turn the button or push the knob.



Some examples of commands that the game recognizes are shown below.  These

aren't necessarily commands that you'll ever type while playing the game, but

they illustrate some of the verbs and sentence formats that you may use.

    ASK WIZARD ABOUT WAND





OTHER CHARACTERS



You may encounter other characters in the game.  You can interact in certain

ways with these characters.  For example, you can GIVE things to them, and you

could try to attack them.  In addition, you can ask characters about things:



    ASK WIZARD ABOUT WAND



Some characters will tell you quite a bit in response to such queries, while

others will be more taciturn.



TIME



Time in the game passes only in response to commands you type.  Nothing happens

while the game is waiting for you to type something.  Each turn takes about

the same amount of time.  If you want to let some game time pass, because

you think something is about to happen, you can type WAIT (or just Z).





SCORE



The game assigns you a score while you play, indicating how close you are to

finishing it.  At certain points in the game, you will be awarded points

when you solve some puzzle or obtain some item.  The score is intended to

provide you with a measure of your progress in the game, and increases as

you get further in the game; you never lose points once they are earned.





REFERRING TO MULTIPLE OBJECTS



You can usually use multiple objects in your sentences.  You separate the

objects by the word AND or a comma.  For example:



    TAKE THE BOX, THE FLOPPY DISK, AND THE ROPE

    PUT DISK AND ROPE IN BOX

    DROP BOX AND BALL



You can use the word ALL to refer to everything that is applicable to your

command, and you can use EXCEPT (right after the word ALL) to exclude certain

objects.



    TAKE ALL

    PUT ALL EXCEPT DISK AND ROPE INTO BOX

    TAKE EVERYTHING OUT OF THE BOX

    TAKE ALL OFF SHELF



The word ALL refers to everything that makes sense for your command, excluding

things inside containers that are used in the command.  For example, if you

are carrying a box and a rope, and the box contains a floppy disk, typing

DROP ALL will drop only the box and the rope; the floppy disk will remain in

the box.





"IT" AND "THEM"



You an use IT and THEM to refer to the last object or objects that you used

in a command.  Some examples:



    TAKE THE BOX

    OPEN IT

    TAKE THE DISK AND THE ROPE

    PUT THEM IN THE BOX





MULTIPLE COMMANDS ON A LINE



You can put multiple commands on a single input line by separating the

commands with periods or the word THEN, or with a comma or the word AND.

Each command still counts as a separate turn.  For example:



    TAKE THE DISK AND PUT IT IN THE BOX

    TAKE BOX. OPEN IT.

    UNLOCK THE DOOR WITH THE KEY. OPEN IT, AND THEN GO NORTH



If the game doesn't understand one of the commands on the input line, it will

tell you what it couldn't understand, and it will ignore the rest of the

commands on the line.





AMBIGUOUS COMMANDS



If you type a command that leaves out some important information, the game will

try to figure out what you mean anyway.  When the game can be reasonably sure

about what you mean, because only one object would make sense with the command,

the game will make an assumption about the missing information and act as

though you had supplied it.  For example,



    >TIE THE ROPE

    (to the hook)

    The rope is now tied to the hook.  The end of the

    rope nearly reaches the floor of the pit below.



If your command is ambiguous enough that the game doesn't feel safe making

assumptions about what you meant, the game will ask you for more information.

You can answer these questions by typing the missing information.  If you

decide you didn't want to bother with the command after all, you can just type

a new command; the game will ignore the question it asked.  For example:



    >UNLOCK THE DOOR

    What do you want to unlock the door with?



    >THE KEY

    Which key do you mean, the gold key, or the silver key?



    >GOLD

    The door is now unlocked.





UNKNOWN WORDS



The game will sometimes use words in its descriptions that it doesn't understand

in your commands.  For example, you may see a description such as, "The

planet's rings are visible as a thin arc high overhead, glimmering in the

sunlight."  If the game doesn't know words such as "rings," you can assume

that they're not needed to play the game; they're in the descriptions simply

to make the story more interesting.  For those objects that are important,

the game recognizes many synonyms; if the game doesn't understand a word you

use, or any of its common synonyms, you are probably trying something that is

not necessary to continue.





SAVING AND RESTORING



You can store a snapshot of the game's state in a disk file at any time.

Later, if your character is killed or you find that it has become impossible

to finish the game (due to a lost or broken object, for example), you can

restore the state of the game exactly as it was when you saved it to the

disk file.  You can save your position as many times as you like, using

different disk files for each position.  Saving the game also allows you to

play the game over the course of many days, without having to start over from

scratch each time you come back to the game.



To save the game, type SAVE at any prompt.  The game will ask you for the

name of a disk file to use to store the game state.  (You will have to

specify a filename suitable for your computer system, and the disk must have

enough space to store the game state.  The game will tell you if the game

was not saved properly for some reason.)  You should give the file a name that

does not exist on your disk.  If you save the game into a file that already

exists, the data previously in that file will be destroyed.



When you wish to restore a game, type RESTORE at the command prompt.  The

game will ask you for the name of a disk file that you specified with a

previous SAVE command.  After reading the disk file, the game state will

be restored to exactly the position when you saved it.





SPECIAL COMMANDS



The game understands several special commands that you can use to control it.

You can use these commands at any prompt.



AGAIN or G:  Repeats your last command.  If your last input line was composed

of several commands, only the last command on the line is repeated.



INVENTORY or I:  Shows the list of items you are carrying.



LOOK or L:  Shows the full description of your location.



OOPS:  Allows you to correct the spelling of a word in the last command.

You can use OOPS when the game displays this complaint:  "I don't know the

word <word>."  Immediately after this message, you can type OOPS followed by

the corrected spelling of the misspelled word.  You can only type one word

after OOPS, so this command doesn't allow you to correct certain types of

errors, such as when you run two words together without a spce.



QUIT:  Stops the game, and returns you to your operating system.



RESTART:  Starts the game over from the beginning.



RESTORE:  Restores a position previously saved with the SAVE command.



SAVE:  Stores the current state of the game in a disk file, so that you can

come back to the same place later (with the RESTORE command).



SCORE:  Shows you your current score, the maximum possible score, and the

number of turns you have taken so far.



SCRIPT:  Starts writing everything you see on the screen (your commands and

the game's responses) to a disk file.  The game will ask you for a filename

to be used for the transcript; you should select a filename that does not yet

exist on your disk, because if you use an existing filename, data in the file

will be destroyed.  Use the UNSCRIPT command to stop making the transcript.



TERSE:  Tells the game that you wish to see only short descriptions of

locations you have already seen when you enter them.  This is the default

mode.  See also the VERBOSE command.



UNSCRIPT:  Turns off the transcript being made with the SCRIPT command.



VERBOSE:  Tells the game to show you the full description of every location

you enter, whether or not you have seen the description before.  By default,

the game will show you the full description of a location only when you first

enter it, and will show you the short description each time you enter the

location thereafter.  Of course, you can get a full description at any time

by typing LOOK.  See also the TERSE command.



VERSION:  Shows you the current version of the game.



WAIT or Z:  Causes game time to pass.  When the game is waiting for you to

type command, no game time passes; you can use this command to wait for

something to happen.





COMMAND EDITING AND RECALL



On most computer systems, the game has a special feature that allows you to

use your keyboard's editing keys to modify an input line as you are typing

it, and to recall commands that you have previously typed for editing and

re-entry.  The specific keys you use vary depending on your system, and some

systems don't support this feature at all; see the system-specific

documentation for more information.



While you are typing a command, the game allows you to go back and change

part of the line without "backspacing" over the rest of the line to get there.

Simply use your left and right cursor-arrow keys to move the cursor to any

point in the command line.  The BACKSPACE key deletes a character to the left

of the cursor, and the DELETE key deletes the character at which the cursor

is located.



You can insert new text at the cursor simply by typing the text.  You can

press the RETURN (or ENTER) key with the cursor at any point in the line (the

cursor need not be at the end of the command line).



You can recall the previous command that you  entered by pressing the up

cursor-arrow key; pressing the up-arrow key again recalls the command before

that, and so forth.  Using the down cursor-arrow key reverses this process,

until you get back to the original command that you were typing before you

started pressing the up-arrow key.



Once you have recalled a prior command, you can re-enter it by pressing the

RETURN key.  In addition, you can edit the command, as described above, before

entering the command.



The exact number of commands the game retains depends on the lengths of the

commands, but more than a hundred of the most recent commands are generally

retained at any given time.





REVIEW MODE



Another special feature that the game supports on many computer systems is

called "review mode."  The game remembers text as it "scrolls" off the screen;

by invoking recall mode, you can go back and look at text that is no longer

visible on the screen.  On most systems, review mode is activated by pressing

the function key F1.



Once in review mode, the status line that is normally at the top of the

screen will be replaced by the review mode help line.  This line shows the

keystrokes you use to view previous screenfuls of text, and also shows you the

key that exits review mode and resumes normal game play (this is generally the

game key that you used to activate review mode).



While in review mode, your screen becomes a window onto the text that the

game has stored away.  When you first activate review mode, you are looking

at the very bottom of this text, which is the screenful of text that was

just displayed.  Use the up and down cursor-arrow keys to move the window up

and down.  Pressing the up cursor-arrow key moves the window up one line,

showing you one line of text that has scrolled off the screen.  Most systems

also provide keys to move up and down by a full screenful (also called a

"page.")



To resume game play, press the same key that you used to activate review

mode.



The number of screenfuls of text that the game stores away for review depends

on how much text is actually on each screen, since the game has a limit on the

number of characters it can store, not on the number of lines.  Normally, more

than twenty of the most recent screens of text are saved and available for

review at any given time.
