     	Yes, it's an archive.
    	You need the LHARC program. I'm sure it's somewhere in WJG::AMIGA:
    or TAPE::USER2:[AMIGA]. Make sure you get the latest version (2.0 I
    believe)

    And a darn good one at that too, I wanted to pack 11 IFF pictures on a
    single floppy, about 1.1 meg worth, ZOO got it down to 850K (or about 10%
    compression on average) LHARC got it all the way down to 650K (or about
    30% compression).  The only drawback, is that it takes a looong time to
    compress but with an Amiga, this can just be done in the background
    while you do something else.

Here is another plea for a VMS version so I can check out the archive before
downloading. Anybody working on one?
Dave

    There are several tools on VMS for doing Lempel-Ziv compression/
    decompression (LZCOMP/LZDCMP).  However, they are incompatible 
    with the LHARC utility used on the Amiga.
    
    It might be possible to backwards engineer a VMS LHARC using
    archives, and the algorithms from LZCOMP/LZDCMP, but... who's
    got the time?   Has anyone contacted the LHARC author with
    this request.

ZIP compresses to about the same size as LHARC, but does so much faster.
ZIP also has an intuition interface (sorry, no CLI) that makes it pretty
easy to use and straight forward. Many BBSs are now using ZIP. There
might even be a VMS version of ZIP.

    Has anyone tried LHWARP from FF295 (also on TAPE::)?
    
    Where is ZIP?? - can it please be uploaded by someone.
    
    regards and thanks

    ZIP really does have a sharp looking GUI.  Real smooth.  If they'd
    added a command line option, I'd have used it for my archives.  I'm in
    the process of re-compressing my archives and chose Lharc because I
    could use it from a shell script.

    re: pleas for VMS LHARC
    
    Somewhere over in the MS-DOS archives (arrgh! nodename flees my
    memory!) is source in C and 8086 assembler for the composite 
    Lempel-Ziv-Huffman coding used by LHARC.  This program only compresses
    one file at a time, similar to VMS Compress.  However, its power
    comes from the combination of two encoding schemes.  The compression
    scheme it uses is NOT compatible with straight Lempel-Ziv compression.
    
    Recent articles on Usenet have discussed the structure of LHARC
    archives.  So it is possible that some enterprising soul could create
    a VMS LHARC.
    
    Looks like LHARC may turn into more than just the
    archiver-of-the-month, eh?  :-)

Here is a script for automatically converting a zoo file to an lzh file.
Change the lock and unlock commands to suit your needs. Your drives
might be different. Use the protect command to set the S protection so
you can run this as a command. Also, be sure to specify the entire path
for the zoo files like this example:

ZOOTOLZH DH0:downloads/*.zoo
Next reply contains one for ARC to LZH. Same rules apply.

Oh, BTW, the "re" command in those two scripts is my alias for "return
back to the top level directory."

    OK, I am still looking for the mysterious LHARC thingie.  Could someone
    point me to one, so I can look at the WB20PICS.LZH thing?
    
    Thank you.

look in WJG::AMIGA:LHARC10.ARC;1

Now does anyone have either a VMS version OR the source code so that
I could make one if I had to?

See note 3734!

    Has there been any further releases of LHARC.EXE for VMS since the
    first FT release?
    
    Still looking for wildcard support.

    
    Steve, has not yet put the wildcard extract into lharc, but the
    wildcard add does function.
    
    The latest/current version is kept in CGFSV3""::amnew:lharc.exe.
    
    Apparently Steve has not kept up with putting the latest version in
    amnew: but assures me that it is now current.
    
    LHARC V1.0 is the current version and supports the wildcard add.
