<A NAME="IDX6"></A>
<P>
The environment variable <CODE>GZIP</CODE> can hold a set of default options for
<CODE>gzip</CODE>. These options are interpreted first and can be overwritten by
explicit command line parameters. For example:
<PRE>
for sh: GZIP="-8v --name"; export GZIP
for csh: setenv GZIP "-8v --name"
for MSDOS: set GZIP=-8v --name
</PRE>
<P>
On Vax/VMS, the name of the environment variable is <CODE>GZIP_OPT</CODE>, to
avoid a conflict with the symbol set for invocation of the program.
