Remove whitespaces from $args (no replies)

Hi,
Tell me please, how can I remove all spaces from $args ?

I create solution, it remove up to 5 spaces. But it not best way i think.

if ($args ~ (.*)\s(.*)$) { set $args $1$2; }
if ($args ~ (.*)\s(.*)$) { set $args $1$2; }
if ($args ~ (.*)\s(.*)$) { set $args $1$2; }
if ($args ~ (.*)\s(.*)$) { set $args $1$2; }
if ($args ~ (.*)\s(.*)$) { set $args $1; }
