FWIW, I installed the package on my Windows machine to see what happens.
-gzsave- works admirably; the 55MB file I tested it with was compressed to
3MB.  Unfortunately -gzuse- couldn't handle the extraction of the dataset;
the compressed file has a stata temporary name with a .tmp extension which
didn't get renamed to .dta during extraction, so Stata delivers an error
message.

r610: file C:\DOCUME~1\jwalla\LOCALS~1\Temp\ST_0500000e.tmp not Stata format

I manually extracted and renamed the file and stata worked with it just fine
however, so if someone wants to make a Windows port of the package it
shouldn't take much work.  I'll use it anyway as an archiving tool for the
moment.

I should note that my system has WinRAR on it, which is gz capable.  It may
be that a Windows computer without WinRAR (or something like it) wouldn't
work with the gzsave package.

Dear statalist,

Thanks to Kit Baum, a new package called 'gzsave' can now be downloaded 
from the SSC archives. To install just type:
	
	ssc install gzsave

The package is aimed at Unix/Linux/MacOSX-users (Kit made me aware that 
gzip is installed by default on MacOSX, thanks!), and is described as 
follows in its abstract:

	Use these routines to save and use datasets compressed by gzip on 
Unix/Linux/MacOSX. They share syntax with Stata's save and use commands.
