[Note: This program is majorly awesome and massively cool, not to mention
 intensely radical.  It effectively DOUBLES your available RAM!  For an
 impressive example of it in action, check out MAPD and MAPD2 in the
 WORK directory on this disk.  -jkh-]

Hi there!

This is my first attempt to publish one of my programs to anything other than
FidoNet sites.

It is a rather small but interesting one: Redundance Fighter V1.2, an object
packer for the 48sx written in ML.

Try it out - it shortens RPL programs typically to about 60% of their size, ML
programs about 70-80%, and graphics become smaller approximately like when you
use the "GraphicObject compresser" published in the past.  [Note: Lutz is
referring to PGROB and UPGROB by Erik Bryntse.  Note that the bugs associated
with PGROB and UPGROB are not found in PF, which seems to be totally safe to
use.  -jkh-]

The instructions are rather brief:

RF . . . a RPL program for more comfortable compression of either an object in
         level 1 or an object named in level 1.  Allows conversion of the
         packed file into three formats: 

         .RFF  the original string created by RFP
         .RFE  a self-uncompressing object (uses RFU)
         .RFP  a self-uncompressing and evaluating object

         After the compression is complete, these three options will appear on
         menu keys.  Press the one you want.

RFP . . . compresses an object in level one     (ML)

RFU . . . uncompresses a string created by RFP (ML)

That's the whole thing!

[Note: Do not be alarmed if the display turns off and the annunciators blink
 fitfully while RF is running.  RF turns the display off on purpose (it can
 run faster that way) and uses the annunciators for scratch memory (which
 also provides you with something to look at while waiting).  -jkh-]

It's a good idea to put RFU in your HOME directory, so any program can unpack
itself without problems.

Hope to stay in contact,
                          Lutz Vieweg.
