Core Wars Pro Instruction
-------------------------

Your task in this game is to write a program (virus) that will fight
against the other ones. Of course it is supposed to win!

You have a special language called 'Redcode' and 10 instructions that
you are able to use. Such a 'warrior' you can save on the disk in two
ways:

-source code (you can edit it anytime, etc.)
-compiled code (the program is ready to fight).

Other Rules:
------------

-The war is played in the computer's memory (numbered from 0 to 7999).
-Addresses 3999 and 4000 are the same!
-In every turn only one instruction out of each program is being executed.
-Every byte that's situated in the game area is composed of 3 parts: 
  -order's code
  -argument a
  -argument b
-Arguments might be labels,still (whole numbers from -7999 to 7999)
 and expressions.

Redcode Language Instructions:
------------------------------

 CODE INSTRUCTION ARGUMENT ITS MEANING

  0       DAT       B      You can't execute this instruction, any try
                           to do this will destroy the whole prog.
  1       MOV       A B    Send contents of cell A to B
  2       ADD       A B    Add arg. A to B and put its result in arg's
                           B area.
  3       SUB       A B    Substract arg. A from B and put its result in 
                           arg.'s B area.
  4       JMP       A      Jump where A will show.
  5       JMZ       A B    Jump, but only when B is equal to 0 (zero).
  6       DJZ       A B    Jump, but only when B is bigger than 0 (zero).
  8       CMP       A B    Compare A with B and if the arguments are 
                           different,skip the next instruction, then.
  9       SPL       A      When this inst is found, the program gets 
                           parted into 2 programs, working alone. If you
                           wanna win, both parts ought to be detected 
                           and destroyed!
 10       PCT       A      The cell that A pointed out is protected! 
                           When tried to destroy, it does, but after the
                           2nd attack after the 1st, only the 'protected 
                           status' gets removed!

These are all the instuctions that you might use.

How to handle the program:
--------------------------

You can use either Commodore mouse (1351) in the port 1 or joystick in
port 2.  in the main menu you can choose:

*EDITOR*

After picking up this option the editor part gets loaded. You can 
choose, then:

-LOAD SOURCE TEXT
-SAVE SOURCE TEXT
-REDCODE EDITOR (you enter the editor, pressing run/stop makes you go
 back to the menu)
-COMPILE (you can compile your source code,then it's ready to fight)
-MENU
-DIR

*TRACE*

You can trace your program while its works. The available options are:

-DIRECTORY
-LOAD FIGHTER (you load a compiled prog)
-TRACE
-BACK TO MENU

*WAR* 

This window looks exactly the same as the previous one. the only 
difference is:

-LOAD FIGHTER (you load two fighters, yours one and the other you
 want to fight with).

Also trace option is shown as -WAR-. When chooing it,the fight begins.
Every coloured point on the screen shows one instruction. Later on 
horizontal lines are seen... built out of the points! The rest of the 
available commands are:

-DIRECTORY
-DOS COMMAND

No comment about these.

And that's it. Enjoy playing this game (if you ever do, what I doubt,
:-)).
