                          =======================


-------------------
  Whatz that for?  
-------------------

XorCopy changes the name and CRC of a .COM file randomly. 
This is to avoid their deletion by Boomlab and other
BBS-Ad-Killing upload prozessors.

C:\>XORCOPY file.com
This command will crypt the file with XOR-for-COM by using a random key.
The crypted file will be written to a random filename, like HXSZJHQL.COM.
XorCopy will also generate a file called VAR.BAT. If you run this file, 
it sets the enviroment variable ADNAME to the random filename
[SET ADNAME=HXSZJHQL.COM for example].
I coulden't write the enviroment variable directly from XorCopy, coz
MS-DOS doesn't allows accessing the enviroment-table of higher programs than
the current one, like COMMAND.COM. [I could do it anyway, but this would just 
be a very dirty method.]
Use this variable to automaticaly do things with the newly created file:
Run it:				%ADNAME%
Kill it:			DEL %ADNAME%
Copy it to a floppy disk:	COPY %ADNAME% A:
Upload it:			HSLINK -P4 %ADNAME%
Add it to a ZIP-File		PKZIP TRASH.ZIP %ADNAME%
Move it online to download	MOVE %ADNAME% D:\ZIP\UPLOAD
...and so on....

  How to install for PCBoard:
-------------------------------- 

1)  Put XORCOPY.COM in your \PCB directory. [or \PCB\NODE1...]

2)  Edit your PCBTEST.BAT file.
    Insert something like:      

    XORCOPY INTRO.COM      ; INTRO.COM is your BBS-Ad!
    CALL VAR.BAT           ; This batchfile is created by XorCopy. 
                           ; It sets a enviroment-variable called ADNAME 
                           ; to the name of the scrambled COM file.
    PKZIP %1 %ADNAME%      ; %1 is the name of the ZIP-File to add the
                           ; BBS-Ad to. PCBoard provides this name.
                           ; %ADNAME% is the name of the scrambled BBS-Ad 
                           ; from the enviroment.
    DEL %ADNAME%           ; Cleaning up...



I hope you understand now how this works. If not, call Trioptimum and 
ask me. 
And tell me if you know a way to improve this confusing documentation
or the useless XorCopy.
