PFXpak 1.7e
Please distribute this program only with its documentation.
Please forgive me any errors in this readme: As I am a german, I use
my english only once in a while.
1. Features
This program is used to pack other programs. It uses the older version of
the LHarc-compression-routine, therefor it is compatible with LHarc.
The code produced by this method is aprox. 5% larger than standard LHarc
1.13-code, but it is still bettern than ARC. After compression a verry small
decoder is added to the code. The decoder will start its work automatically
after starting the program. It will do its work at a rate of aprox. 100KB
per second.
Theoretically, it is possible to extract pfxpak-archives with all versions
of LHarc (even under MS-DOS), but due to a mistyped constant, it will work
at 1.13.04.
2. Compresion.
If your program is able to work with the fastload-bit set, click on
fastload first. This will set the bit in the original program. (If it
is already set, PFXPAK will recocnize this).
After clicking at the [Compress], select the program. A dialogbox will
show you the status of compression. The first number is the process-
indicator, it will count up to 100%, the second line shows the ratio.
At the end, the fileselectorbox reappears to give you the chance of
changing the name or path for the compressed program. You may, of
course, just hit [Return] to let the name and path unchanged. The
number of bytes reduced is shown on the last dialog-box.
2. Decompression
Normally the programms decompress themselvs. If it doesn't work, you
may decompress it either with LHarc or with PFXpak. If you use LHarc,
you only have to rename your program to programm.LZH and treat it as
a normal Archiv. If you use PFXpak, you have to select the compressed
file in a fileselectorbox.
3. Shareware
This is not free software. If you paied a public-domain vendor for
this program, you paid for the service of copying and shipping the
program, not for the program itself. This means that nothing ever
get to the autors from this sale.
You are allowed to copy PFXPAK and to give it to your friends or a
PD-Library. It is not allowed to sell this program. It is not allowed
to copy this program without its documentation or without the
registration-form.
If you register, you will receive
- A newer and better version of PFXPAK. This version includes:
- recusive collecting of executable files. This mean you are able
to pack your whole disk with a few mouseclicks.
- A virus tester. The idea behind this is that every PFXpacked
program has the same code. The registered version of PFXPAK
knows every byte of all version of the decoder. Therefor if
a virus infects a PFXpacked program, it MUST change one of the
well known bytes of the decoder.
- The registered version runs as an accessory.
- A free copy of LZS2PFX. This enables you to add other files to
your programs (for example the readme).
- A free copy of fortune. This program knows about 250KB of nonesens
and reads it in compressed form. If you put it into your auto-
folder, you will get up to 5 jokes every time you restart your
system.
- A free version of AFX. This is the same as PFX, only it works
on data-files.
If you like to register, or if you have any questions, please write to

The decoder was designed by Markus Fritze.
4. Commercial use of PFXPAK
If you like to deliver your software in compressed and runnable form,
you have to
- register your copy of PFXPAK ($US 15)
- send 2 copys of your program (including manual etc.) to me.
It is also possible to pack you data-files with a linkable version of
AFX. The linkable version of AFX is availabe for $US 50 (please tell,
wich compiler you are using).
