Two alternatives that involve no coding:

1.   SAVLIB LIB(YOURLIB) DEV(*SAVF) SAVF(YOURLIB/YOURSAVF) DTACPR(*YES)

This uses OS/400's own built-in compression.  I've found it reasonably
good.  It is not the default.

2.  If you don't like #1 for some reason, there's another way.
(Assumes Java installed -- you don't need to program in Java for this)

   First, FTP

   ftp to your own machine.
   namefmt 1
   lcd /somewhere/in.your/ifs
   put /qsys.lib/yourlib.lib/yourfile.file  yourfile.savf

   Then, under QSH:

   cd /somewhere/in.your/ifs
   jar -cf yourzip.zip yourfile.savf

The Java "Jar" command does zip files (a Java Jar file is nothing more than
a zip, really).  I haven't done both, but I doubt if you get much
improvement over doing both for doing just the first one.  It might even
get larger.
