<tt>Hi Jan,<br>
<br>
Of course you can, but you need to evaluate the variables before
passing it to the route (as param)<br>
<br>
<span style="font-size: 10pt;"><tt><tt>$<tt>var(msg<tt>) = </tt></tt></tt></tt>rm
+ "received on " + $var(hostname);</span><br>
<span style="font-size: 10pt;">route(logger, $var(msg));</span><span
style="font-size: 10pt;"></span><br>
<span style="font-size: 10pt;"></span><br>
<span style="font-size: 10pt;">Regards,</span></tt><br>
