 <p>To separate multiple keyword=value pairs, use <code>;</code> (semicolon). Since the shell normally eats <code>;</code>, the recommended usage is to write the assignment inside qoutes, e.g. <code>JTREG=&quot;...;...&quot;</code>. This will also make sure spaces are preserved, as in <code>JTREG=&quot;VM_OPTIONS=-XshowSettings -Xlog:gc+ref=debug&quot;</code>.</p>
 <p>(Other ways are possible, e.g. using backslash: <code>JTREG=JOBS=1\;TIMEOUT=8</code>. Also, as a special technique, the string <code>%20</code> will be replaced with space for certain options, e.g. <code>JTREG=VM_OPTIONS=-XshowSettings%20-Xlog:gc+ref=debug</code>. This can be useful if you have layers of scripts and have trouble getting proper quoting of command line arguments through.)</p>
