according to wiki page, sip-router has improved while and switch syntax, but how about if condition syntax? can i write, for example, if (script_function() == 2) ... of do i still need to do script_function(); if ($retcode == 2) ... by the way, i didn't quite understand the case example (first case expression): switch($var(x)){ case / "^[abc]" : what is the meaning of /? -- juha
