Uncompress utility

[James N. Petersen]

I know that this is not a question that will challenge the wizards, but
perhaps someone can help.  I am using AT&T System V/386 R3.2.2  I have
obtained some files that have been compressed, using zcomp, I assume
since the last part of the file name is .Z  My system, unfortunately, does
not seem to have uncompress or zcomp in its base UNIX.  Does anyone know
how I could get the source of this utility?  An anonymous FTP site
would be preferable.

Thanks.
