It also is not a loop... so in order for a [break] to show *any* speed improvement in switch.. you'd have to type out one heck of a long manual switch context... and if you are going to do that, you might as well use [loop].. which already has a break. Something like: [loop start=1&end=10000000] [showif [url][interpret][var[index]][/interpret][/url]=somvalue]
[break] [/showif] [/loop] I suppose if we ever replicate a PHP-like switch, [break] would make more sense. Donovan -- Donovan Brooke WebDNA Software Corporation http://www.webdna.us **[Square Bracket Utopia]**
