I had a program that is either PD or ShareWare, called "Mash", which was a
UN*X compress compatible program, and would either compress or expand files.
Unfortunately, I don't know where it is anymore (I am about 6 months behind
in cataloging my various download disks; one of these days, for sure .. :-)

Also, if my memory serves me correctly, MRBackup (which is on at least one
Fish disk) compresses its files via the same format that UN*X compress uses,
and even uses the .Z extensions (at least an older version that I once looked
at did this, I don't know about the current version, which I haven't looked
at.)

BTW, I have no idea whether either of these Amiga programs supports all of
the possible options that UN*X compress does, especially relating to the
number of bits of Ziv-Lempel codes (i.e., 14 vs. 15 or 16, which require more
memory).
