OK, in DRL terms this would be something like this (I've not checked the syntax, but it gives you an idea):-<br><br><span style="font-family: courier new,monospace;">function boolean isTooOld(Calendar usd, Calendar crd, int age) {</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> crd.add(Calendar.DAY_OF_YEAR, age);</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> return crd.after(usd);</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">}</span><br style="font-family: courier new,monospace;"><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">rule "old claims"</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">when</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> Parameters( $usd : userSpecifiedDate, $param : maxAge )</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> Claim( $crd : claimRequestDate )<br> eval(isTooOld( $usd, $crd, $param ) )</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">then</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> System.out.println("that's an old claim");</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">end</span><br style="font-family: courier new,monospace;">

<br>
lets say instead of =now() I am using a user-specified date(usd). I want to<br>
calculate (usd - claimRequestDate) in the Condition something like <usd -<br>
ClaimREquestDate) > "$param"<br>
<br>
I the data for that condition I want to put an integer say 65 - the rule<br>
should fire when the condition is met<br>
