Ĵ PROGRAM PURPOSES 
 

This  program  is  intended  to protect OPL written programs or games from
being decompiled with RevTran v3.3.

It is of use to programmers that does not want other users to hack his own
program by decompiling it, especially to shareware programmers who want to
protect  their  programs  or  games  from  being  illegally  registered by
hackers.

It is simple to use, as nothing has to be modified in your source code.


Ĵ COPYRIGHT 
 

This manual and the program here  described  are  copyrighted  (c)1995  by
Marco Aicardi.

This program has been  completely  devised  and  written by Marco Aicardi,
Genoa, Italy, hereby referred  as  Author.  All  rights  reserved  by  the
Author.

It is a violation to copyright laws to try to reverse compile the program,
to  hack it or to study the methods which it is based on. If you want, you
can ask the Author the general methods on which his work is based.


It is considerated a violation of copyrights to release programs that make
users able to reverse compile OPO/OPA modules protected with OPL Prot.


Thanks to Steve Litchfield for some beta testing.


Ĵ HOW TO OBTAIN IT 
 

OPL  Protect  is not a Public Domain software. It shall not be distributed
by anyone other than the Author.

Contact the Author by e-mail to obtain a limited demo version of OPL Prot.
The  demo  version  will  let you check if OPL Prot fits your purposes. It
will protect only programs with a  maximum  of 3 procedures and the source
code should not exceed 100 lines. It will have only  1  protection  method
and  the  protected  modules  will  display  a  nag screen with your name.
Modules protected with demo version of OPL Prot *MUST* not be distributed.


I do not succeed in contacting me by e-mail, please ask  Steve  Litchfield
for my new e-mail address writing to: slitchfield@cix.compulink.co.uk


If you will think OPL Prot will fit your own purposes, you  will  have  to
register  it.  OPL  Prot  has  no  royalties and will be usable on as many
programs as you wish.

The registration fee is $50 or 30 with 5 different protection methods.

Shipping  OPL  Prot by uuencoded e-mail is free. Add 2 or $3 for 3" disk
shipping. Add other 2 or $3 if you send a bank check.

As  the  Protect efficiency will be based on the program diffusion, I will
*ONLY* register users who will send me a test  version  of  his  work  (or
screen shots by fax) or who have already published shareware programs.

I will *NOT* register programmers which are all over the  world  known  as
decompiler makers. I am  very  sorry  about  this,  as  I think Mike Rudin
(RevTran maker) is a great coder, but I can't let anybody have in his hand
a way to hack my Protector.


Ĵ WHY REGISTERING 
 

After  paying  the  registeration  fee,  you will receive OPL Prot package
containing:

* Your own last OPL Prot version
* 5 different protection methods user-selectable
* Upgrade information at minimum fees
* Complete documentation

You  will  be  granted  the  authorization  to  spread  your  own programs
protected with OPL Prot, as long as you insert a OPL Prot copyright notice
as reported in the documentation you will registered version.


Ĵ USE 
 

OPL Protect Registered  has  command  line  arguments  not stated here but
explained in the package documentation.

Simply start PROTECT.EXE giving it  your  source  file name on the command
line, like this:

PROTECT MYPROG.OPL

You can supply an .OPL or an .OPP extension only (this to  avoid  possible
mistakes).

You will get your protected file (i.e. MYPROG.OPA or  MYPROG.OPO)  in  the
directory you are working in.

You must have  S3ATRAN.EXE  v1.62F  (23/02/94,  100426  bytes long) in the
current directory when you start PROTECT.

S3ATRAN is supplied with both the demo version and the registered package.
It  is  a  freeware  program  from  Psion  Plc.  Copyright  (c)  Psion Plc
