     To quote the Commodore folks, "It's in there!"

     Compress *is* the uncompressor.  It will vary its behaviour
depending on what its name is, or what command line switches it is
given.  Compress does just what is says.  Copy compress to uncompress,
and you get the decompressor.  Copy compress to zcat and you get a
decompressor that goes to stdout instead of a file, for use in pipes. 
Here's the command line switches:

    Compress:
    -c  Compress file and send data to stdout, without writing to a
        file.  Nondestructive.

    -f  Force compression, even if file does not shrink, or <filename>.Z
        already exists.

    -v  Verbose.  Print (un)compression stats to stderr.

    -b  Set maximum size of common substring codes, in bits (ranges
        from 9 to 16).

    Uncompress:

    -c  Uncompress file and send data to stdout, without writing to a
        file.  Equivalent to zcat.

    -v  Verbose.  Same as above.


     Note that setting bits to 16 will chew up *large* amounts of
contiguous ram.  You need at least two meg of Fast Ram to use compress
at that setting.  Setting -b 13 seems to be the largest size that will
work reliably in a one megabyte Amiga, in my experience.

     You're welcome.  I hope this helps.
