Hello,<br>
I once found in the wiki a page explaining how to "substring" a channel<br>
variable,<br>
something like<br>
<@[intra]lanman> 12345 would be 345 if you do ${var:2}<br>
<br>
I can't find that page on the wiki anymore, any hint on were it could<br>
be? :-)<br>
<br>
Also do you think it could be useful to extend this functionality with a<br>
sort of Java indexOf() to extract a specific substring from a variable<br>
(but without knowing its size like in the example above)?<br>
<br>
Regards,<br>
Claudio<br>
